It's not the cheapest, but it goes pretty far. Most importantly, it sands easily and it's a simple one to one mix. I found it at Boater's World.

If you were deeper in the glass I would say use a filler with glass in it but It does not look like you need that. Again two part fillers will stay. Single part auto fillers I am told will shrink over time. This is why people use the epoxy or two part fillers. I used the 3m filler on my 15 project over 5 years ago and it has held up great.

Filling spider cracks are for those who are not going to paint their boat, and only have a few. rich Rich
