  1. Re: Any issues with microballoons and talc for fairing? What ratio?

    I never mix anything else in with the balloons, vertical or not. I just use enough balloons to make a mixture that doesn't sag - find that ratio and mix carefully staying with it. Yes, you do cut...

    Yeah, we saw them out last weekend with the stern-steerer association but there wasn't much wind on Saturday when we were on the ice. The launch site was on the north side of Mendota, but the only...

    Re: Prohibition stripper

    In small quantities, the filler will be fine. You can often even out alcohol based stain with a second coat. It dissolves the first coat and allows you to move it around again.
