I posted my response in a thread titled SPI Epoxy Primer Opinion.
AWESOME stuff so far. Sprays like paint, covers well, seems to stick like glue and the finish is smoooth and semi glossy. Like I have posted, the blitz black fans gotta look at this stuff. Outside temp was about 72-75 and went down to upper 60s a few hours later and down to upper 50s at night. The day before it was in the upper 80s raining and humid - Minnesota ya know. I have not sanded it as of yet, maybe tomorrow. I was around 30lbs psi with a conventional gun trigger pulled. It reminds me of some of the marine resin based products I have used, almost like a heavy bodied LPU at first glance. I cannot comment on how it holds up as that would take more time. At this time, I recommend this product without hesitation. I am not a professional, but of all the primers I have sprayed, this was the most user friendly. The mix is 1 to 1, easy! When I first opened the can, I had to mix the heavy solids from the bottom for a couple of minutes. After that mixing was a piece of cake. They also send you a tech manual on how to use of all their products as well as painting tips. The product arrived at my door in 3 days like they said. This is the stuff for me in future projects. I just wish everything worked out this well. By the way, a tad over a hundred bucks for 2 gallons of product!!!!

i am a big fan of souther poly's products. in my shop we strictly use only their primers and clears and find them to work great. i have used the epoxy primer and found it to be comparable to the top brands but the only thing i didn't like was that those solids in the bottom of the can you talked about we a little on the gritty side so when i sprayed it and it dried, if you look across the surface there would be thousands of small specks in it. if you are spraying a 2k surfacer over it then this doesn't matter but you could never use it as a sealer without having to sand it first to smooth it out. i was curious if you had the same results??? i also have this problem with the regular and high build urethane primers but they always get sanded. thier turbo primer doesn't have this problem, it spays wet and slick.

I went and looked at my car very carefully. I do have some small particles here and there, but for the most part, the finish is very level and smooth. From the DP I used to spray, it has a higher gloss and seems to be more of a resin base than the PPG. In my case it does not matter either way as I sand everything prior to finish. Just a habit or maybe saving grace for me.

I have had excellent results with R-M (EP series) epoxy. Sticks to bare metal like glue and is also an excellent sealer. Never had a failure.

Need to do some touch-up painting in the engine bay on my Mercury and the posts seem to really favor the Southern Poly Products paint. Could someone give me their web site address so I could see if maybe they have a dealer near here or are they a mail-order only? Also, do they sell the finish coats too?
Tks, Charlie

hi, the web address is www.southernpolyurethanes.com. you probably wont find a local dealer. you will need to goto www.bakerpbe.com. that is the main distribution warehouse. get the phone # off the site and give them a call and tell them what you need. be sure to use the part #'s. they usually ship the same day and i could be wrong but i believe the more you order the more they discount the shipping and even if they dont the shipping really isn't bad at all.

what would you need as far as grit to scuff cured and weathered epoxy?

Is epoxy primer the type that you can add filler(bondo) on top of?

Keith

Yes

Not sure what to use on other epoxies for roughing up, but on SPI's, I was told to use a red scothbrite pad and it seemed to work well.

Ron

I've been to Southern's site. Are using the 1 part epoxy primer or a two part system?

Two Part. = 1:1

Thanks Barry. Any idea exactly what it's called? Sound
decent.

Keith

#6600 series epoxy
Quart kit = 2 sprayable quarts
Gallon Kit =2 sprayable gallons

gray, white or black.

I'm contemplating Epoxy priming after all sheetmetals repairs are made, however will not do any additional surfacing or painting till the summer. Do you see a problem with that? Does the epoxy have to be painting within a certain window?
