A couple months ago I decided to give the UV finish thing a try. I was pretty impressed with the finishes Mike DaSilva and Joe Souza are getting with the stuff. Plus it's plenty hard and tough. And goes on thin. The topper was that, being pretty new to this craft, I wanted to be able to string one up and hear it, before starting the next one, instead of the 6 weeks it takes me to do a lacquer finish. Last year I made one change, and built that mistake into four ukes before I realized it. I figured UV would be a great finish, and fast, and easy. You know, like *the* answer.
So I ordered the CureUV system, with the light, filler, gloss and safety equipment. I followed their directions to the letter, but just couldn't get it to work for me. I tried a few suggestions from the interwebs, they didn't work for me either. I set the light aside for the time being until I felt like really getting into the learning curve.
Fast forward about a month to the Healdsburg Guitar Festival. Cardinal had a booth there and I stopped by and talked to their chemist, Mac, for about an hour. Mostly about their UV finish. He told me they formulate theirs with a solvent base so it would flash over and you could spray several coats before hitting it with the light. They use a pre cat vinyl sealer so the gel filler doesn't seep in farther than the light can reach. Then he told me they were offering free samples if I signed up for them at the show. So of course I signed up.
After a few emails and phone calls over the last week or two, when I got home this afternoon there was the box from Cardinal on my front porch. I built a little concert pineapple out of sapele and spruce to use as a platform to try this stuff out, and it was ready for finish. Oh, and he threw in a trial size of their lacquer, too. I like this company already.
I sprayed two coats of precat about a half hour apart and let it dry for an hour or so. Wiped on the filler and lit it up. Leveled it with 220. sprayed 2 coats of gloss on the top and 3 on the back and sides, lit and leveled it. Sprayed one more coat on the whole thing. Spent less than a half hour to wetsand with micromesh from 1500 to 6000. Then buffed it with Mezerna medium and fine. The cheap Chinese belt on my buffer has stretched a bunch so I couldn't really put much pressure on it before it slips. I'll fix that tomorrow and rebuff.
This stuff sprays so well, so easily. No dust or nibs stuck in the uncured finish. It's like what I had hoped UV would be like. I can't think of words to describe how happy I am with this. I have all day tomorrow to finish a koa tenor that was going to get lacquered.
I put 2 ounces of finish in the cup, and with overspray and solvent gassing, I'd guess maybe 15 grams tops of finish before sanding, and I'd bet the top has no more than .002 on it. I'll weigh and try to measure it tomorrow.
No dust, no nibs, no learning curve..... here's a couple pics.... four hours from box to buffer
