almost nobody is allergic to pure chocolate, I'm told.

I'll take your chocolate, Alan, cockroach bits and all. :lol:

I'll skip the epoxy and continue to do my seal coat using a natural cage-free organic sealer. Straight from the chicken!

Old fashion paste wood filler between the first coats of shellac works very well. If you color the filler a shade or two darker than the wood I know you will like the results. Just make sure the filler has shrunk well before building up the surface finish. For the best finish I fill the open grain a second time before doing top coats. Filler on the top sounds like a lot of trouble with no return for the effort.

Would epoxy be one solution to make an ¨arm rest¨?
I mean if you paint a very thin layer epoxy (thinned with alcohol) 1/4 moon shape on lower bout bass side and then fp it over when doing the top?
Anybody done this?
This would add a little bit to stiffness but almost nothing to weight.

I'm I the process of pore filling with system 3 SB112 for the first time.When it begins to kick the fumes become brutal.Be sure to have a window open near by and a fan blowing behind the work aimed towards said window.I didn't upon first application and became quite dizzy.
Although it takes a while to harden the process starts fairly soon.I worked in the boat building industry for several years in the past and should have known better.best of luck!
