Enamel, lacquer, urethane? Which paint?

[rbruno68]

I am in real need of paint advice from you guys that have painted your trucks. I am new to the painting and not sure exactly all the differences. If you are looking at my build series, I am getting ready to start to paint the cab of my 63. I called TCP Global yesterday to order the correct fawn for the interior. The guy was very nice and helpful, but unfortunately a lot of what he was telling me was going over my heard. I have basically two situations in painting. And, I want to do it all in single stage. My steps/plan are epoxy, body filler, high build, color. The question comes with types of high builds and color.

Situation 1. The interior
The interior of the cab has been complete media blasted and painted with Shop Line JP375 epoxy paint. I have a small area to body work and put on some filler. When I sand, I know I will break through to bare metal. I am looking for a high build that can go direct to metal. I looked at Shop Line high build but I don’t see that it is direct to metal. The guy at TCP Global has a DTM high build I could use, but he said I couldn’t use it on the exterior patches. More on that later. He also said I could use enamel or lacquer and recommended lacquer but also said I could use that on the exterior. What did you guys use for the fawn paint? Lacquer, enamel, or urethane?

Situation 2 Exterior patches paint blend
I have the cab corners and rockers that I need to paint. Same epoxy down first. But, I don’t plan to paint the entire cab. I want to try and blend the paint. Knowing the paint is not going to match aside, he said that the high build they had would not go over existing factory paint or at least the one he recommended. So, for those of you that have only painted your patches, what type of DTM high build primer did you use, urethane, polyester, etc and what type of color paint did you use to blend with the original paint? Again, this isn’t about color matching, it is about what is going to adhere to the overlap parts of the original paint.

Sorry this is a long post, but just need some solid advice and dumbed down for a beginner to understand.
Thanks
