- go over entire hull with polyester glaze (mix little at a time and spread thin)
- sand with 220, 320
- repeat untill satisfied (320 grit)
- sand all to 400 grit
Conclusion:
In the end it turned out real well. I probably added alittle more than I should have to some spots but... Im no pro and at most it might wiegh a pound or so more. Also I found it tricky to fillet filler in to cups on the sides, just be carfull not to put too much on there. It took a lot of sanding and sanding and sanding. It never looked perfect or good enought for me, but once I painted it it looks SWEET!!! Remeber its just the bottom and dosent have to be perfect. The main point of doing this it to get the protection and strenght back of a new hull.
