The question is, what is the quickes drying 2K or epoxy primer out there? Not having a spray booth or heater system. Is there anything on the market that drys like laquer primer? The temp here is 50 to 65 degees.

I don't know who has the fastest, but what really does it matter? Prime it, leave the thing to cure (2K doesn't "dry") and when it is ready sand it. It isn't like clear or something, if it gets dirt in it or something because of it being wet, who cares. What is the issue you have?

Martin,
I am just curious. Back in the 70's I did some painting and we used laquer primer, sealer and enamel single stage or laquer paint. Now getting back into doing some painting alot has change. The only thing I don't like about the new paints out there is the primer takes to long to cure. The last coat of primer took four days to cure.
I went and talk to the paint rep. about it, found the problem, I am putting to much on it at one time. So I was just curious if there was something out there that had a faster cured time.
Buy the way, I have read most of your post and I just want to thank you for spending the time to help us.

Pat, thanks for the kind words, glad to be of help. Primer taking four days is way off and your rep was right that build up of the material is certainly going to do that.
I remember the first thing I painted with (my ....my..Darn if I can remember the name right now) one of my first HVLP guns. It has a "atomize control" unlike any gun I have ever seen. You can turn this thing down so the paint literally "falls" out of the gun producing zero overspray. I figured this was perfect, it was a vintage gas pump, it didn't have to be glass smooth, orange peel was fine. I'll save some paint and not make a mess of the area with red acrylic enamel. Well, the same thing happened as your primer, it took DAYS to cure. It is simple, it was FULL of solvent. How long would the primer in a can take to cure hard if you just took the lid off? It needs to be atomized and layed in neat little layers on the surface allowing them to flash off and "dry" (that is sort of "drying" as it flashes before "curing") before applying the next coat. Applying the primer too fast between coats, too slow of a reducer, too cool temp in the shop, too slow gun travel, ALL of these things are EXACTLY the same as a poorly set up gun, they are all trapping solvents in the film.

Go back and read the "Basics of Basics" on atomzation/gun set up. Not so much to learn how to set it up, I'm sure you got that. But to get a FULL understanding of what it really is to have a properly atomized film. Read it five or six times slowly without interruption. WHY you need to set up the gun properly and apply the product properly is explained and the WHY is much more important to get out of the article than "how". "How" you can figure out, you need to understand "why" first.

It would blow you away how curing can be sped up by taking your time applying it. No, it will not cure or dry as fast as lacquer, it just isn't going to happen. But the end product is SOOOOO much better it is worth the wait.

Martinsr, Your gun set-up help me alot on laying out the paint. I have read you basics of basics about 5 times. I think the problem is not understanding how the paint works, applying the primer to fast. So I will rethink my process and go from there.
Thanks, Pat
