[Public-list] That brown goo from weeping blisters

[Janet Kirk]

I had the same thing in the main cabin, so you're not unique. I was told 
it's deteriorating "bondo" (auto body filler) that the builder used to 
fillet the sharp cabin angles.

At any rate, I tried a couple of things including aluminum engine paint to 
reseal it without success. What finally worked was sanding and painting 
with Kilz primer.  That was 7 or 8 years ago and it's still ok. I notice 
the same thing starting in the forward cabin now, so one of my winter 
projects will be to repeat  the process there.

As a separate issue, I get mildew breaking out in the cabin interior every 
couple of years, which, again, I've been told is caused by a previous owner 
painting the interior with latex over the original paint. It comes off 
easily enough by wiping with a bleach/tide solution, but is a chore, 
getting bleach in your face, etc. I'll probably continue doing that though 
because I hate the thought of trying to sand the interior to bare 
fiberglass and repainting. Painting over the latex probably wouldn't  work
