Hi all,
I have a 2008 Four Winns H220 with a scratch (gouge) in the hull. The gouge is about 18 inches long, 1/4" wide at the worst, and about 1/8" - 3/16" deep (maybe a little more). It is definitely into the gray fiberglass under the gel coat. It is located about 12" above the water line on the side of the hull.
I would like some advice on how to properly repair this. My thinking is this:
Use 80-100 grit paper with my DA sander to sand down to the bottom of the scratch and feather it out to maybe 2-3" wide.
Apply the appropriate fiberglass in layers working from the middle (deepest) out to the edges.
Once the fiberglass cures I can block sand the entire area down (including the adjacent gell coat) and reapply new gel coat.
Does this sound about right. I do have some questions though:
Where do I get the appropriate fiberglass and resin? What brand and part number?
Do I build the new fiberglass all the way up to the level of the existing gel coat or do I leave it a little shallow and allow the new gel coat to be about 1/16 - 1/8" thick?
Thanks for any help you can provide!
