on my aluminum mast
is flaking off - mostly under improperly bedded stainless steel hardware
, but also under other hardware
, and in general. I figured once I had all the hardware stripped off anyway, I should give serious thought to repainting it all. As far as I can tell, the metal wasn't properly prepared before the paint
went on - I haven't found any zinc chromate looking stuff under the paint. There appears to be a layer of grey stuff under the off white paint, but that's it. Same is true of the boom.
Of course, though a good deal of the paint is coming off, and I have little hope that the rest won't consistently follow suit, some of it is on there tenaciously enough that I have to put work
into getting it all off. I understand trying to simply (re)paint the mast
without po is a pointless half measure.
So my question is, how to get the paint off? I tried some random hardware store stripper that said safe for metal and removes epoxies and polyurethanes, among other things. That was about as effective as smearing mayonnaise over the paint. I didn't have much hope it would work
. I'm finding many things online in the 80-100 price
range, twice as much as a gallon of this stripper, but don't want to lose the time (not to mention money) of ordering something else ineffectual.
I'm not sure what kind of paint it is - from my limited experience, I'd guess it's polyurethane
. It's a pain to sand off - and though I suppose they're pretty thick, it kind of makes me nervous to be removing aluminum
from a 1/5" thick spar. Besides, I have very little hope of sanding
the paint off in the little nooks and crannies in the mast and boom tracks, masthead, etc. I'd really like to strip the stuff chemically if at all possible.
Has anyone any suggestions for stripping the stuff off? I know methylene chloride is potentially unsafe and serious stuff. But would it even remove this paint? If so, I'd be willing to give it a try, if it's safe for the aluminum - at least there isn't any gelcoat
to worry about. But is there something better? Something safer, or more effective? Is methylene chloride even going to do the job?
Fingers crossed there's a good solution to this problem. Thanks for your thoughts!
