Order of things
I have read a lot of threads as to what material to lay first, everyone's opinions on etch vs epoxy etc. I think I understand for the most part. The question I have is... are there general rules as to what materials can be laid on top of previous materials? For example, I read that some preferr to use epoxy to seal the bare metal... Ok so now that you have sealed with epoxy, is it ok to lay a 2k urethane build primer or should you use a polyester filler? I mean is it a no no to put urethane on top of epoxy? For another example, I read another post where someone stated to shoot bare metal with etch, then follow it up with epoxy, then follow with a 2k build primer, block and base etc... why would you follow the etch with epoxy, or if you use etch is urethane ok on top of it? what about polyester? Sorry, I'm just confused...
Thanks
Bill
