Just thought I'd start a new thread for this one. (I'm told those are the rules when you get off subject)
Searching through the forums I find different answers for this one. It's not a big arguement yet, so let's make it one! haha
Painting aluminum. Before I sink down the deck for good in my rebuild/hackup I'm going to paint the insides so she looks better. Everyone kind of says to use Rusto Self Etching Primer, then whatever the heck you want on top of that. After talking to a friend of mine that works on small airplanes, he says different.
Just to cover the basics before this gets to be a "look around on the forums dummy" subject, this is what I've found.
What I've found around iboats: You MUST use self etching in order for anything to stick to aluminum. period.
What airplane man states: If you use self etching on aluminum, then paint over it it will actually continue etching in the sealed in coat. Eventually it COULD do damage. His disclaimer... Aircraft have strict regulations, and everything you do or have done must be documented and be to code. BUT he has seen it in action, having to strip down newly painted pieces of a plane because etching primer was used, and finding that it affected the aluminum.
He says they have to (first strip it) then a seperate etching chemical, then a neutralize it with another chemical to STOP the process. Then paint it.
What are your thoughts. And what have you all done? and has it held up? Thanks in advance!
