Re: Lexan/polycarbonate vs acrylic

Guys, Dow's data sheets say that 795 is suitable for use on GLASS and aluminum. It is not stated anywhere on their data sheet that it can or should be used on acrylic or fiberglass. It is a silicone rubber sealant, and traditionally those ALWAYS peel off acrylic and release after they've worked for a while.

So...Try 3M's 4000 adhesive, which is designed for polycarbonate and acrylics. Or something else. If the data sheet does not expressly say you can use it with acrylic--it will fail.

VHB tape was just on the history channel, as "one of the world's ten strongest products". But again, that's subject to following the directions.
