I did a lot of body work a long time ago, when everything was lacquer based. My son now wants me to 'help' him do some body restoration work. I've read all the 'training' articles on the site and archived posts, but I'm still a bit unclear about the order of using the new materials.
First question: If I understand it correctly, the order of application is:
1. 'Bondo' Filler
2. Polyester Glazing/Spot Putty
3. Guide Coat
4. Epoxy Primer or Polyester Primer
5. Guide Coat
6. Repeat 4-5 until happy (unless you've really screwed up #1)
7. 2K Primer
8. Top/Color Coat
Have I gotten it right?
Back when I used lacquer, a primer coat as always applied before the spot putty, but probably because the spot putty was really just a very thick lacquer primer.
2nd question: Iis there a difference between Epoxy Primer and Polyester Primer, or are they same thing... Does the Epoxy/Polyester Primer or the 2K primer require a special gun, or can it be shot with a standard HVLP gun?
3rd question: At what point is the body work relatively water resistant? The paint shop said they will apply the 2K primer just before the top coat, so I'd rather not shoot it myself if the work will be relatively water resistant after the Epoxy/Polyester Primer, as it's gonna take us some time to work our way around the whole car.
I wanna get some info from the folks on this site before I go down to the Body Supply store and talk to a kid with no experience and only knows what the boss or the mfg TDS 'suggests'.
