Epoxy primer or SElf Etching - Team Camaro Tech
2000年4月12日 · The self etching primer really locks into the bare metal and gives it good corrosion resistant but it's not real tough - which was the reason for covering it with a layer of the primer surfacer. When the body work in an area was finished I sprayed the self-etching primer on all bare metal followed again by the primer surfacer.

Self etch primer over filler? - Team Camaro Tech
2006年6月24日 · I would use that U-tech epoxy. Etch primer is an old dead technology that belongs in the trash can. An urethane primer surfacer is what is referred by "2K" primer.

Epoxy Primer over etching primer - Team Camaro Tech
2012年2月19日 · DO NOT get confused between Epoxy Under Coat and Epoxy Primer Sealer. DO NOT use the Primer Sealer on metal. Primer Sealer on metal is, to say the least, garbage in my opinion. It hardens like brittle plastic, too hard to sand properly and easily chips. I recommend RM Epoxy Undercoat on metal. Once applied you can do about anything you want ...
How well do metal-etch and bondo get along? - Team Camaro Tech
2002年2月4日 · I personally use an etch primer like Variprime or PPG Dx1791 and never use a conditioner. Then the urethane primer over that. But that isn't the only way to do it and using a conditioner is fine. I just find that it is easier to spray an etch primer. The DP90 is a black epoxy primer made by PPG and a very good product. RandyB, Evercoat is ...
PPG DX1791 Self Etching Wash Primer - Team Camaro Tech
2002年5月21日 · It means that you have to apply your epoxy or urethane primer over it within 24 hours. If you wait longer than the 24 hours you must sand and re-apply the DX1791.
