I've used CA to finish about a 1000 pens and several bowls.
And one complete guitar body.
The finish can be polished as if it were an acrylic to an extreme gloss.
If applied thick it gives a very nice depth and seems to magnify the brilliance of the wood.
The finish is very hard and resists scratching, and it makes a good coating over softer wood.
This one I used CA to build up thick hard layer and then finished the surface with TruOil.
The most important thing to do before you start is to have a bottle of debonder in reach.
Surfaces with a curve are much easier than flat surface.
Apply a coat of thin CA to start, just flood it on.
This puts down a base coat that makes applying the main coats smoother.
For the majority of the finish.
Use medium gel CA and apply with a paper towel folder about 7 layers thick.
Believe it or not the best Paper towel to use is Kirkland brand from Costco. Whatever fibers they use say intact in the PT and dont fall off into the finish and the fibers have a slower reaction to the CA. Some PTs act as an excellarator to the CA.
Apply about a teaspoonful of CA to the surface and use the towel like a trowel. Work fast, maybe about 5 seconds and throw the towel away.
If you try to go one more pass you will stick the towel to the surface (bad)
Spray hardner and repeat on the next area. keep going until entire surface is covered.
Apply as many layers as you need to have enough thickness to sand it flat without sanding through...and that is hard to know when.
Wet sand level with 400g paper and then move up in grits through 2000. Then use micro mesh up to 15000g.
Then hand buff with an acrylic polish. Then finally finish off with a paste wax and it will look like shinny water.
Avoid power buffing as heat will melt the CA finish.
It's not easy but once you learn the technique you can finish a body with a high gloss finish in a days work. No drying time.
It takes about 6 ounces to finish a solid body.
Don't forget the debonder and don't panic if you finger gets glued down.
