Am currently using on a 1990 bumper pull trlr...u can imagine the dried out and leaking attachments on the sides and roof....so far it seems to be the ticket...and you can paint it if you want to.
This is a great product for outdoor furniture and as a primer for exterior doors and windows.
However, it seems like it will do what we want... to protect the new pan from sitting water that could rust it.
Had to use 4 coats of it to get a good seal so a little trial and error, or just be over cautious and do more than you think you need.
Used this to fix a leak in the metal roof of our sunroom.
I tried to close a gap in a strip of rubber.
It stopped a leaky pipe for a couple of weeks, but the leak has slowly started coming back and is getting worse and worse.
You can spray it, come back the next day, and it falls off.
This stuff does not work on gutters at all, very poor product that does not seal anything.
Does NOT sealBUY LLIQUID RUBBER don't waste your MONEY like I did.
