<satisfied sigh>
So, I've been trying, literally, for years to get a nice sprayed on finish. I've started over so many times, changed techniques/finishes and started over again so often, I figured it would never, ever happen and that I was doomed to wipe-on or brush-on.
Boy, did I surprise myself.
I have 15 Christmas boxes made up, and opened up the 18-month-old pre-cat that was in the nice Graco gun. There were beautiful green crystals all over everything in the gun. After a good 30 minutes of cleaning every pore of the gun, and then spraying 1/2 cup of lacquer thinner through it, I started playing in earnest with the knobs on the gun. Guess what?! They have a PURPOSE! Each of them does something different!
So, after getting a nice mild aerosol-ish pattern I liked, I cleaned and dried the gun one last time, filled it with a filtered well-mixed 1/2 Deft Gloss from a gallon can and 1/2 lacquer thinner. I sprayed some test pieces, slowly, with light overlap, (way more finish than I would have expected) and was stunned.
I grabbed one of the boxes and went to town. With all the spray practice I've had, it was a breeze. I layed down two coats on inside/out of each of the boxes, (with full respirator and plenty of open-air venting) and they look incredible.
So, what was it? Am I really that stupid? My guess is a number of things. One - thinning. Way thinner than I've ever tried (and way, way heavier coats than I thought). Two - Clean equipment. Never cleaner. And filtered mixture. Three - NEW finish - none of that old stuff that's been laying around. It's all going to the recycling center tomorrow. Four - correctly adjusted gun - this is the biggie. I was always hesitant to go over about 35 PSI, as this is a "HVLP" Graco gun. I ran it this time at 90 psi, cranked down a bit on the gun side with the lowest control knob to what I'd guess is 60 or 70. So my attempts before led to orangepeel, too light a finish, too much spattering, runs, sags...there was always something.
I knew that someday, all these techniques you guys teach would come together into one happy juncture, and that day has come. I'm hooked on spray finishes, and now am going to shoot a couple of coats on the car, the deck, the pool, and that deer eating my grapes.
Thanks, guys!
