Fiberglassing mat over cloth

[T-Bucket Bob]

Can you fiberglass mat over cloth? I did some fiberglassing with some cloth over
foral foam. I would like to strengthen it up with some mat. Can it be done?

Sure. Just scuff up the previous glass really well. Like with 36 grit to put some good scratches in it.

I do combinations of different weaves all the time.
