I've used "rust mort" waaaaay back ...before ospho....its the only other rust treatment product I've used...the ospho is so much better I forgot about that stuff...but ,by all means try them both...
Thanks Dinger, I never would have thought of splitting this in to two threads.Great idea!!! This way we can save EVERYTHING....
I'll get back to this just as soon as I can,I got caught up in some unexpected remodeling at a rental property and it'll take a few days to finish but I have three more tests to do that wont take much time coming right up..
.One involves 1/8"quares insted of 1'' squares
then bondo on both 1" and 1/8" squares and knocked off.
if that dont do it. I'll try to scrape it off with a razor scraper but,
One way or another that primer is coming off the hood even if I have to sand off ....That way we can see which side feathers better,treated or untreated...Either way it works out, I gotta say that dang epoxy is a lot tougher than I thought...I really dont think the others I've used would have made it this far......You guys have been great...Thanks.....Mike O.

my best advice,,,contact SEM who makes Rustmort for how to remove the white stuff...
no it is not zinc phosphate,,,it's the result of the acid reacting with the good steel and the white stuff is not bonded well to the steel....
to zinc phosphate surface coat something there has to be zinc mixed in with the acid (like PPG 520)
Rustmort msds says it is just acid and alchohol:
been awhile,,,hope all is well with you!!!

Keep going Deadbodyman! I'm waiting for the part on heavy rust.
I'm using a product called Rustmort, which is a mix of phosporic acid and alcohol. Directions say to wait 24 hours and rinse with water.The product is sold as a rust converter, not a remover, which Ospho also advertises itself as, as far as I can read. Am I wrong?
I'm using it on the bottom of my pickup box, which was heavily rusted. It left a sticky residue on what paint was left. I also found it left a heavy white residue, which I'm thinking now, that the metal had a zinc coating, and the acid made zinc phospate. It's proving a b...ch to get off. I just spent 3 hours wire wheeling it and not finished yet. Any help there?

If you CAN still get it, you might want to get more than you think you need, in case the next time you need it, it's been outlawed.

Great thread, despite (or is that because of?) the animosity...
I wonder if I can get that stuff here?

Like it or not it your name always comes up as soon as the word ospho is brought up.... I tried not use your name or your company ,even covered the SPI label with tape.
But when you make statements like, do not not use ,you bring it on yourself.
I was hoping you would chime in and help me with an aheasion test.I thought you would be the best one for advice...After all it is SPI epoxy I'm using...
I'll post any links or old threads I like and at will, to make my point....Like I said before I was using this stuff twenty years before you even read the directions*************and take the good with the bad your epoxy is my second favorite product and everyone knows that too.
Anyone can pm me. I give my number to anyone that wants it...always have

No things don't change Cobalt, first read what I said follow instructions, I used it under lacquers years ago and it stated rinse with water, don't anymore.
Also see the statment, "rinse with water", It was stated in other post I use it for small parts and use 2 rinse buckets like the e-coaters do.
I still tell peopel it will work if nutalised.
Learn to read!

The following was asked on 11-15-05:
Having read most if not all the threads here about ospho and similar rust conversion treatments, I have seen a lot of “learning” has been done; those who would say one thing at one time, have changed their minds due to their having “learned” ‘things’. Exactly how this “knowledge” has been attained, and how that "knowledge" has affected the veiled endorsements- I know not. I seem to remember that there was something said to the effect that things change over time.
I would have thought that the partial, conditional "endorsement" of the product would have been sufficient. Apparently, the "knowledge" that was gained in the interim has negated the proviso-laden statements, to the point that ospho has now been relegated to the "don't use" category.
It is interesting to see how the positions have morphed over time. At least DBM's position on the subject- right or wrong- has been steadfast throughout. No waffling.

Please, do not use my name in your tests and please do not quote me unless you use the whole statement I made.
A while back in the other threads I posted what the acid film will do to three different chemicals, related to just three different products, it was lost and buried with bs add ons, so no need for me to bring it up again as it gets proven over and over again here that facts tend to get buried for other personal gains.
None of your test addressed the factual chemical reaction and most important in that companies own tech sheet it says—Works best under oil based paints—who uses oil based paints? That should sum the stuff up right there.
I have posted elsewhere that I get over 100 failure calls a year related to acid film and all but about a half dozen of these were other products because if they used SPI, they would have seen all the warnings and called for directions first.
I help these people best I can as usually they worked two years on their project and killed the family budget to buy the paint and it kills me, to tell them, start over and it’s really not my problem, since they used another brand.
Do all the homemade tests you want but do not associate me in anyway.
SO post your phone number and I will send these people to you, just keep my name off this stuff.

Hwy, It may be hard to believe, but that old Plymouth is the SOLE reason were having this discussion today.
My son came down to Ga. to live with me and had an interest in cars so I started searching for a cool looking one we could build from the ground up that was was in very rough shape because I hate chopping up a valuable rare car.
I saw an ad for a 48 ply biz coupe and thought we would go look at it (I always wanted a biz coupe)Well, from the road (1000') it looked Sooo cool I didn't think THAT was the one for sale.
Anyways when I saw the look on my boys face (a 15yr old future hotrodder ) he said : That cant be the one!!!! HE loved it too.
Well, it WAS the one... we bought it and the change in him overnight was simply amazing.
He went from sleeping till noon and getting waited on hand and foot to waking me up at 5:30 every morning and making breakfast for us,just to go to the shop and work on that hopeless rust bucket.We got very close that year ,we got it sub framed and running using junk yard stuff I had laying around (mostly camero stuff)(below is one of the first pics of the car after a years work)
well, his old girlfriend called and wanted to hook back up again, she called him every night and he got Love sick and moved back to NY.
I worked on that car every spare minute I could (in secret) to show him what can be done if you stick to your dream and don't give up.
two years later we were talking on the the phone and I told him I had been working on that car all this time and it was in primer now.I had just got a deal on a fresh 350 so I got in and started it up with the open headers.He got all excited ,he couldn't believe I was working on the car all this time and never told him.....
Well to make a long story a little shorter ..He wanted me to join the human race and get an email address to send pics and vids ,I did, but for some reason I wasn't able to send them (files to big) So he told me to join www.streetfire.net and I started learning how to use the computer.One day I pecked in "Hot rod" and stumbled onto this site...I joined and right off I got into an argument with Barry an a few other members about Ospho,got suspended for two weeks and the rest is history.that was a year ago
I saved the thread to remind me from time to time.http://www.hotrodders.com/forum/mast...ml#post1114939
keep in mind I had no idea who Barry was. I came onto this site recommending ,mainly two things SPI and Ospho...Shine told me who it was I was telling didn't know what heck he was talking about...LOL ...ONE thing's for sure Barry and Shine and I might just be the three most stubborned dinos here.at least NOW I can use this thing a little better ,,,no machine will ever get the best of ME,LOL....BTW, my wifes friend said it looks like the police were dragging a lake for a body and this was pulled up.thats when I got the unusual nickname DBM.....I hope Ya'll liked my little story,long in the tooth as it is...

Here's an old thread (5yrs ago).look at post#3 http://www.hotrodders.com/forum/comp...pho-74054.html
At the time of this thread I was already using Ospho for over twenty years...
He got so many complaints he just recommends NOT using it.(I asked him the same question a year ago)
I know Barry gets swamped with phone calls about this stuff,But if he so negitive with his comments on the subject I never would have wrote this.
It's just mt attempt to set the record straight...Hopefully this will help HIM as much as it helps the DIYs
As you guys can see its not that hard to use and adhesion is NOT an issue if used properly.
Personally,I believe the primer sticks BETTER with Ospho....But his primer is also very good....so far I just cant PROVE it sticks better...
But thats NOT why I use it... as you can see ..it does stick at least AS good.
Its very important to wipe off the excess and sand before primer....
The first thing you'll notice is how much more filth comes off the metal after you think it's clean (sanded with 80 gt) that alone amazes me every time I use it.
|04-10-2010 03:30 AM|
I can't speak for Barry but I would guess that most people don't use it properly and it has caused him much grief.
|04-09-2010 06:57 PM|
That's a cool ride you have there , what's the engine for it? RED was right, we probably should refrain from adding comments until you're finished; I couldn't resist. Should we have another thread called "ospho solution questions and comments"?.... Just a thought ...Anyway, Great job and a sincere thanks for your time....after all YOU already know how to make it work, lol.
