I have a gouge on the bottom of my cougar boat by arrow glass of memphis, I think the previuous owner hit a rock , the gouge is about 2 feet long, I sanded the area about 2 inches away from the gouge in all directions and smoothed down the edges in the gouge,I'm using "PROFESSIONAL Fiberglass Resin 4104" from AutoBody Master It Contains Polyester Resin, I layed three layers of evercoat Sea-Glass Fiberglass Mat it says .84m then the little 2 in the corner for squared is after the m, I am getting air bubbles in spots I will try to post pic's, and I was also wondering If I am doing it right with the right stuff I thought I reseached the problem but after doing a search on the site I am starting to second guess.
