Little white dots? As much as they may offend your eye, this is not the time to deal with them. Paddle the boat now and enjoy it! Come autumn, when you are putting things away for winter, fix these spots and all the other dings and scuffs that a season of paddling will create.

While the spots are visible they will not compromise the strength of the boat.

The actual repair technique is fairly simple--sand away the glass over the affected area, sand a tapered area an inch or more into the glass around the spot, apply resin and a patch of glass cloth over all the area you sanded. Apply one or two more coats of resin to fill in the weave of the new cloth, waiting 8 to 24 hours between coats. Wait 2 days to 2 weeks for the resin to get good and hard, then sand the patched area flat, removing the edges of the patch which are higher than the surrounding area. Apply one more coat of resin. Let it harden, then sand it smooth with fine sand paper before varnishing.

Since you'll probably be giving the entire boat a light sanding and varnishing at the end of the season itt makes sense to wait until then t also do any fixes.

You'll have all summer to get a quart of ePoxy resin, a yard of glass cloth for patch material, and a fresh can of varnish.

Storing partly-used cans of varnish is a trick of its own. If you open a can of varnish now then there is no guarantee the stuff will still be good in the fall. Now you can patch thhese spots and not varnish them, but epoxy resin has not got any UV blockers in it so you run the risk of the repaired areas 'aging' or turning color at a different rate than the rest of the boat. That just makes small defects much more visible.

So enjoy the boat the way it is until you have to do the annual maintenance.
