Gelcoat Repair?

[rrack]

We have an ancient Coleman tub that I've managed to keep going through the years.  I have a bunch of small cracks along the top edges and some under the water line in the gelcoat.  No leaks just ugly.  Is there a clear sandable repair that I can fill them with?

I've never done it, but there are gelcoat repair kits available at most marine boating shops...maybe try there?

Are you sure it's gelcoat, and not acrylic?
