flexseal in sealed box?

[jeepguylv]

I was going to build my box today and was wondering if anyone had tried flexseal inside on the seams. I haven't worked with fiberglass before and didn't want to make a mess .

any thoughts ?

thanks.

fiberglass is better. it seals and makes the box alittle stronger as well because it hardens. But honesty with a sealed box flex seal should be fine

yea it's a small 1.5 cube box with single 12" . so if you did the fiberglass would you use just the resin and spread it or do you use the fiberglass cloth then resin over that. I figure I might as well learn, I know a lot about everything else so I guess i'll give it a shot.

$2 tube of caulk is all you need...if your glue joints are good then you don't even need that.
