Bottom job advice needed.
I bought yesterday 1994 Miracle. Upon inspection I found:
1. bottom of the hulls stripped off gel coat at about 1” wide
Probably don't need to add glass to that - it's just the gel coat worn off from dragging it on the beach. I'm assuming the "bare strip" extends aft from the centerboard trunk. A picture would help.
2. crack about 2”-3” long on stripped bottom of port hull
Where exactly is the crack? Is is extending aft from the CB trunk? A picture would help here, too.
3. edges of daggerboard’s wells chipped a bit
Edge of the wells, or the daggerboards?
Use polyester resin for repairs. It's what the boat is made of. Only use epoxy when obtaining good adhesion is a problem or where you absolutely need the extra strength. Polyester does not stick well to epoxy (don't try spraying gel coat over epoxy). For filling dings and fairing, Evercoat Formula 27 is a good, general purpose, polyester filling compound.
