Touching up little knicks in the glass
So I picked up my boat from it's winter "berth" and apart from a really good cleaning, I couldn't help but notice a bunch of little knicks in the fibreglass. The are caused from the occasional bump when I'm landing on the rocks around these parts.
I intend to paint my hull later in the season when it gets a little warmer (we got 2" of snow here today, but the ice is out of the harbour, so going I'm diving!) but I'd like to touch up these little knicks first.
These are all just cosmetic, generally no bigger than an 1/8" in diameter, so I'm wondering about the best way to patch these up. Is there a sort of "Poly-Filla" type product that can just be smoothed in with a trowel and sanded smooth before painting?
I've not asked at my local chandlers, so I hope I'm not asking a really stupid question. It's just that you folks are so smart!
