Underside repair on strikes- ?

[Yanky Bob]

Any links or pics to show a good way to repair "rock rash" on under side of a bassboat? Everything I find on line is about repairing a flat surface or a hole.
My strake on one side has some bad surface damage, to fibergalss matting but, not through it. I think I can do my self but, not sure the best way to keep the contour of strake. I have about three 5-8 inch long area about 1 inch wide. Is it worth masking off or just fading/blending gel coat so, I will not have as much to sand? How do I know how much material to buy. I have done minor stuff on same boat before on keal but, not this big. I figure it on the bottom so I don't care if it is not a perfect color match but, do not want to loose any performance. Perhaps such links could be posted and kept at the top of this board?<br /><br />

I'd like to know this myself. I have some contact areas to the matting but not leaking either.

Reparing a " Strake " is the same as repairing a flat surface, only you will be building up the strake to match the contour, which is done by hand.

Is your gouge on the angled part of the strake ? If so you'll need to build it up in layers to match the original contour.
Easiest fix is using Marine- Tex.

One package on Marine-Tex should repair three 5" x 1 " gouges.

Thank you. The whole strake is gone for about 5-8 inches. Didn't know if there was a shaped tool for such a repair. Supose I could make one out of a pop can or something. Otherwise, I was thinking of using a long ruler length wise to help shape it.

Can I use white Maine-Tex with color and sand smooth and shiny or do need to color match a polyester gel coat to go over it for it to not be a noticable repair?
