Yep. It will have everything you need in it. Put the patch on the inside, overlap the damage with the cloth patch by 1" or so. Be sure the piece is positioned properly before glassing it in, I would hold it in position with some tape on the outside. Clean up with acetone or lacquer thinner.
Just to make sure I understand - use the original piece that broke out and tape it in place on the outside and put the patch on the inside? I feel a lot better about attempting this after hearing from you all. Thanks for that.
