Hi Bigbill....I have been reading all the painting and preping info and have a question for you? When you refer to D/A is that a disc sander? I am getting ready to start preping my 66 Aristocrat and the paint is extremely chaulky and oxidized. I really don't want to use a chemical stripper. I have a disc sander/polisher and was wondering if that can be used to take the paint off.
D/A (dual action) sanders are disc sanders. The disc rotates and oscillates simultaneously. I prefer to remove the siding and chemical strip so cannot comment on sanding beyond what has already been said.
I wouldn't use a disk sander. It can be very aggressive and the skin is soft. To remove the paint completely, chemical stripper is the way IMO. If you just want to buff the paint to rough it up, hand sand or a palm sander.
if you go with stripper make sure you clean it really well before painting.
So if you use a chemical stripper are the certain ones that affects the aluminum more than others? We used the citri-strip because we were afraid of the reaction that occurs with other products, is this true or am I wrong?
I have "aircraft paint remover" on the way. I plan to power wash as I remove small areas. An aircraft mechanic, I fly RC planes with, told me to NEVER let the remover dry. He says it hardens and is like glue. I plan to do the firest striping with the skin on the trailer and "restrip" spots post skin removal. The plan is to reuse the old skins even though are a bit rough.
Is there a kind of soap or detergent that works well on stripper?
My Shasta Airflyte ( in my avitiar) is PROLY a 58 to 62 ...Do you think it needs stripped? The house paint camo job on two of four sides is kinda retro Bwahahahaha

I think that unless you are trying to remove all of the paint (as if to polish the aluminum)...it is not necessary to "strip" off all of the old paint. Our's had very faded original paint. I just wet sanded with various grit sandpaper ( by hand ) finishing with 220 grit. I figured that if after 50 + years there was still paint attached, I might as well just paint right over it. I did use sanding primer. Almost 5 years later there has been fading (red is notorious for that) but the paint is still intact. It all depends on what your expectations are. We just wanted a fresh, clean look...not showroom shiny. We camp in places where we expect scratches and dings to happen.
