UV Sealant

I am trying to seal a sun-roof with clear poly panels - ongoing problem. I used FLEX rubber membrane, but then noticed it was not UV resistant. Any suggestions on what to do to topcoat it?

thanks (primarily a paint contractor, so roofing is a bit outside my normal area!)

Re: UV Sealant

You most likely can't. Is this a polycarbonate panel?

Only thing I have found that is compatible is silicone.

Are you just sealing the leaking holes or trying to coat the whole thing?

The problem is that most sealants will burn the polycarbonate and it will fail sooner.
