I need some advice, help, or maybe just Reassurance.
I'm in the process of painting my 24' Argosy M.H.
I have taken your advice on painting as Gospel, as nothing beats experance!!
The problem that I have is that the paint manufacturers strongly recommend that aluminum must be prepped with acid etch or etch primer.
I explained to any and all who would listen, the concern with rivets and corrosion, they say that it isn't a problem.
WELL---- You say it can be a problem, and I totally AGREE!!
the acid will stay in the cracks and crevices/rivets etc.
It just makes good sense and your experence backs this up.
I have posed the question many times on internet body shop forums such as our forum here, they say the paint will not adhear to the alu. properly if not chemically eched one way or another.
I explained that I have stripped with aircraft stripper and will SAND thourghly
with 150-180 grit then apply epoxy primer then topcoat,
their feeling is do what you want, but be fore warned that it may not bond well and "peel" if not chemically cleaned.
Their help is and experance is well appreciated.
SOOO, where does that leave me?
I have stopped work till I get some sense of direction.
I ALSO have the galvenized end cap to deal with, do I etch it only??
I don't believe this has been addressed in your procedure.
Some how, California seems to be getting closer to Michigan as these problems arise
