Hope I don't get jumped on. I too have shot PPG for a long time. I have done a bunch of fibergl*** cars as well as metal. Just throwing this out there in case anyone cares. When I do a gl*** car I shoot DP epoxy on it, wait 20 or so minutes, go right back in and nail it with as many coats of K-36 as I want. Block it, reprime as necessary, finish blocking wet or whatever. And paint. I flew to the coast and did this car in a week. By myself. Oh yeah, I had a little time left so I did this body also.
Lippy, you said yourself you are spraying K36 and blocking it. That's urethane primer. You didn't stay with epoxy as I'm explaining. Nothing wrong with what you are doing, its what most people do. But's its not epoxy, K36 is urethane.
Slammed, are you serious???? wow . . I went into my explanation based on something that was asked in this thread. Didn't you see it? I started off listing Kirker as a possibility for black epoxy, as the ORIGINAL post asked. No hijack buddy. Then was aksed this . . and went and explained it. wow
I have asked this question before but did not or could noy get thr answer I wanted. Can epoxy primers be tinted ? Case in point I would like to int a grey green closer to a dark green. Also with epoxy once its applied and cured it doesnt matter what is applied latter, correct ?
WIlly, I'm not a chemist, but the only way I'll tint DP is with another color DP. Take that with a grain of salt as I do 80% collision repairs, and don't need comebacks. And yes, almost anything can go over epoxy(DP anyway)--except DP doesn't like etch primer(PPG) Other brands, like...say...Kirker, for instance...you may be able to put anything over that.
The instruction sheet for DP primer covers using it as a high build primer. If you do that on a critical job it should be allowed to FULLY cure before sanding and painting. The heavier it is applied, the longer that takes to fully cure. Yes Correct, but if not done withing the time specified by the manufacturer the primer must be sanded before proceeding.
Not trying to add to the drama but HOK has epoxy that is also a high build primer. Sprays nice, sands nicely, about the same price as DP.
I never put an etch over Kirker, not sure why you would. Basically etch primer is DTM anyway. I have tinted some epoxy for myself, but as said, not worth the comebacks so be careful. I doubt there would be a problem, but when turning a job back to a customer, you don't want trouble. A call to the tech line of the paint manu usually can answer those questions. My suggestions are based on years of doing something, so I'm comfortable with what I suggest. I have sprayed lacquer over Kirker and I know you are getting no chemical bond, so it has to be all mechanical. I recently saw a Vette I did about 7 years ago and it still looks the same as it did when I painted it. I don't use lacquer primers, too much swelling. Good to hear that HOK has a buildable, sandable epoxy. I know there are others out there.
The original question on Sunday was if there was a black PPG primer. I was told there wasn't by FinishMasters, only gray. So thanks to the person who said finishmasters and to the others that gave me the lead. I asked specifically about PPG, not Kirker, which I am sure is a good brand.. as you have gloated about for the last 10 of your posts. There are about 10 other threads pertaining to a discussion of which is better and which is the right way to paint a car, which is not what I asked. I asked about primer only. If you want to yack about how great Kirker is then make your own thread and stop hijacking mine. You aren't really to blame in this, but yes... it is my thread asking about if there was a black PPG primer or where to get it in Indiana/Indianapolis.... If anything else needs to be explained please read above; this is not a thread about how to do a paint job. The information is great, but this has gone so far OT that I barely got my question answered in 25+ posts. That is why I said what I said, not to inhibit your nerd rage
maybe the guy I was talking to on the phone didnt know what he was talking about. I will check into it again tomorrow, thanks
If you asked him for black primer, that's why he said no...cause AFAIK, the is no "black PPG primer".....but there IS black epoxy(DPLF90) Most people.....I say most.....think of primer in the primer-surfacer sense.....whereas DP isn't really a primer-surfacer--it's a primer-sealer. Don't forget the DP402. The mix ratio is 2:1 DPLF to DP402(or 401) Keep in mind it will turn charcoal gray probably by the end of the summer
