FAQ:

Q: What to use as a seam sealer?

A: To protect seams on a vinyl tarp or cover, you can use HH-66 Vinyl Cement as a seam sealer . Just carefully brush the HH-66 right on top of the sewn seams on the underside of the fabric only. The glue will dry clear and after it has cured it won’t be sticky.

Q: How to apply auto seam sealer?

A: Press down lightly on the brush so the sealer is forced down into the seam. But not too hard, you want the edges of the sealer to be a little thick so it looks like a “bead” when you unmask. You could apply a smaller bead, press that in with your finger, then apply another bead and brush it lightly to build up a good bead.

Q: What is a seam sealant?

A: Seam sealant is a chemical coating material used to seal joints in fabric or metal. This product can be used to repair rips or holes, or to reinforce existing seams.
