Sounds like you can perform the operation... Its just more work then may want to do.Picture this....You block sand the whole boat and do repairs. Now you spray many coats of gel. And it looks like a "coble stone" street, now the work... You start blocking it down to a 1200 or even1500 grit, get your buffer out and polish it.... Here's a common prob, if you sand thru anywhere you start over or you will have a "Halo" arond the spot. I have only done a few in 20 years and "I" wont do another. Now I do regel the bottoms when I restore a boat. Then paint it the rest of the way up. Feel free to call if you want more "encouragement"
