Hey Barry,
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

Great thread, despite (or is that because of?) the animosity...

I wonder if I can get that stuff here?

There was a time not too long ago, that I'd have said, "Hell yeah you can get it!" Unfortunately, I hear from my pyro buddies Down Under, that the government's consumer "protection"-type laws there (depending on the state) are getting more Draconian every day.

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.

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?

crownover,,,
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:

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.
