Have any of you ever used a product called "Seal-All"?
It comes in a small tube. It's made by a company called Eclectic Products Inc. out of Pineville, LA.
I thin it down with acetone and brush it on, giving three coats and drying in between.
I had used it before to seal gas tanks so I figured if gas won't hurt it whats a little heat. Works great and sells for a couple of bucks(even better)
