Re: [RBW] cork grips - shellac vs. spar varnish
Spar varnish - is this for boat spars, aircraft wing spars, or both?

You want 5 coats, and wait a day between each coat to let it soak and cure. You apply thin coats and of course the cork sucks it right up. Wait a day and apply another. It won't be until the 4th coat that you can see the cork is sealed and you're apply a build-up. After the last coat, give it two days to cure, and it will still feel tacky - don't worry.

Re: [RBW] cork grips - shellac vs. spar varnish
any weathering application of a flexible fibrous material that will absorb the oils - bamboo fly rods, too - this one was made in 1915 of course the name came from spars on sailing ships http://img.photobucket.com/albums/v728/bulldog1935/estes/Chama/aP7050087.jpg On Tuesday, June 2, 2015 at 11:13:25 AM UTC-5, Jim Bronson wrote: Spar varnish - is this for boat spars, aircraft wing spars, or both? -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] cork grips - shellac vs. spar varnish
I feel a trip to the hardware store coming on... That makes cork grips far more appealing to me. I varnished some skateboard pedal decks, but the shellac whitened in the rain. Can I spar varnish right over the shellac, or do I need to strip the shellac off, first? This is to protect and shine up the bottoms of recycled skateboard squares that snap into clipless pedals to make a platform. Is that even a legitimate use of that material?
