Thanks for your reply, st3gamefarm. Anyone that has had DP-90 separate after applying to the car, or has noticed that DP-90 doesn't dry as quick as it's advertised and is causing problems... please encourage them to contact me. [email protected]

I had to toss the omini 2k primer and chalk up another one as junk not to buy. I should have known better but my guy that delivers my materials doesn't have qts just gallons of primer and about a qt got wasted because it was just too thick to use after a while. Now I take the time to clean the top of the can and seal the primer up well so it lasts longer.

I've had failure with Omni 2K PPG rep paid for the re-do. Paint comming off in sheets, with powder primer residue on it. Car had not even left the shop yet. Hadda strip, and re-prime, with something else. I chose to use Slick Sand on the second go 'round, paint has held up now for about 10 years.

I used DP for many years, it was the "Cat Daddy". DPLF OTOH is crap.
I used Sikkens Autobase for years, was good stuff, prime formula would match perfect. They took out my system, and replaced it with Autobase Plus. I was sorely disapointed with it, and went to Global. While Global is good stuff, It's kinda expensive. And sometimes it's more cost effective to order a pint of DBC, than to mix 8oz of BC.
I've been using 2002 clear since it came out, and just love it. But I tried SPI universal a couple years ago, and found that I like it as well.
I'm still up in the air about SPI epoxy, While it seems to be good stuff, I've had a couple of issues crop up recently, and I cannot say definitevly what the cause is, untill I get into the repair. Both issues, are on my own vehicles, so it will be a while before I get to that.
I will say this though, steer clear of Nason if you want a quality job that will hold up for a long time.

Rustyfender - Could you please contact me regarding this PPG epoxy from 2016? I'd like to ask you a couple questions if you don't mind as I'm having a major issue on a very expensive show car of mine where the painter used PPG epoxy. Please contact me if you can! 205-263-5102. [email protected]

Regarding user "Rustyfender"

I know this is a long shot here, but would anyone have the contact info for Rustyfender should you have had previous discussions with him? It is very important that I get in contact with him regarding his experience with this PPG epoxy failure as I'm having some major issues with the company as well and would like to speak with him to ask him a couple of questions regarding his experience with it.

Please let me know if any of you can. Would like to have Rustyfender give me a brief call to discuss if possible! 205-263-5102. - Terry H., Birmingham, AL

I just found this forum. I would love to talk to you about your issues with PPG. I have a very expensive show car where the paint has been coming off in sheets due to PPG and DP90 failure. Please give me a call to discuss if you don't mind. My number is 205-263-5102. I'm in Birmingham, Alabama.

Thank you! - Terry

But now even at that will pull loose from sandblasted metal, bondo, plastics and sanded metal. I'm even seeing cars at shows where this seems to be a problem any one else experience this as well ???

Rusty -

I am experiencing this same issue on a very expensive show car. Around the time that your post is dated is when this started occurring. This is not an isolated incidence. I have been looking for other people that have had this similar problem. I would LOVE to talk to you on the phone to discuss more. Would you be willing to give me a call at 205-263-5102. I'm in Birmingham, Alabama. I look forward to hearing from you soon! - Terry

I use the same products as Kelly for about 10 yrs. and loving it.

If you are concerned about compatibility, I use SPI epoxy and urethane primers, as well as SPI universal clear coat, all with PPG base coats and have not had any issues with any of the above combinations. I do recommend the SPI base coats if you have the chance to use one of their colors. For a general process, we 80 grit bare metal with a DA and then clean with waterborne then solvent based W&G remover and apply epoxy.

one of my old ppg tech manuals has k36 in it. it was in the kondar days. this manual is from around 84 .

Rustyfender

I believe its a combination of the DP not being what it was and the shrinkage of 36 but I don't believe ancient technology because these things used to work great. Newer tech seems to be the problem from what removed they claim EPA ? I am looking at the products ya'll have brought up and will try, I have been PPG tried and true so not schooled on these and the reason for the post. PPG said to use DX 1791 But P sheet says not to use on media blasted steel or on boy filler so that's stupid for restoration ! Thank for all input I really need it gonna have to swap to something.

i no longer use urethane primer but the turbo is good.

06-23-2016 07:43 AM

deadbodyman

You like the turbo primer? I never tried it. hows it compare to the standard 2k primer?

06-22-2016 07:42 AM

drop the dplf and k36 . switch to spi epoxy and the turbo primer. k36 is ancient technology anyway . primers from the 80's were horrible about shrinkage .
