Anybody ever use this stuff?

I gotta fix a spider crack in my fender and was wondering if by coating the inside of the fender with that truck bed liner stuff if that would prevent a reoccurrence. Anybody ever use this stuff in that application and if so, how's it workin'?

I haven't tried it myself, but I have read that others have tried it with good results, on glass cars. There is some controversy about using it as a sound deadner or steel cars, because some people feels that it will hold moisture (from splashed up rainwater on the road) against the underside of steel cars and cause rust.

I know in the fishing community they rave about it for coating the inside of aluminum boats.
Not only does it help seal loose rivets, it provides a strong non slip surface with amazing sound deading qualities.
So my guess is that if it works for boats and doesn't let water in, it should have no problem keeping water out!(yogi berra speak):o :3dSMILE:
The key is to rough up the surface so it can get a good bite.

I use it on the inside of fiberglass fenders on "driver" cars. Sure does a good job of stopping star cracks from rocks and helps on sound deadening, too.

Thanks for the responses guys. I thought it sounded like a good idea when I first heard of it's impact resistance qualities when used in pick-up beds.
