Hooray for scrapers, even dull ones!

Spray paint is my mortal enemy. Especially spray paint drips. I’ve been finishing an electric guitar for months now, because every time I spray a new coat on, I get drips. When I get drips, my SOP is to sand through to the primer in a fatal attempt to level them. Then I swear, a lot. But I just got a set of scrapers the other day, and even though I haven’t managed to sharpen them satisfactorily, I decided to break ‘em out. I’d put another coat on my guitar a few days ago, and of course got some drips (I really, really suck at this whole aerosol lacquer game). Dull scraper to the rescue! With some careful scraping, I managed to rid myself of those pesky drips without scraping through to the primer! I’ll still wet sand until it’s ready for another color coat, but I think that dull scraper just saved me some sand-throughs. I might actually finish the guitar in this lifetime now. Now I just need to practice sharpening those glorious steel saviors….

Sounds like you are applying too much or holding the spray can too close. Stay 12” away and think many light coats.

Try a hunk of glass ( broken straight edge or cut) as well, curved for hollows and such.
BTW, I am a luthier and know what ya mean about rattle can spray, Stewart-MacDonald sells a good Laq WITH a decent nozzle on the can.

Mist first, I call it a tack coat, then go back and lay on a full wet coat, look at it from all angles for grainey-ness and STOP before it gets too wet. The grains will level out. And wet the floor and all area around ya so dust is not kicked up. I even shoot my sleeves and shirt front w/lac. to keep any dryer lint or dog hair from floating into the wet finish.

Good luck

Yeah, I need to work on my spray technique. It doesn’t help that my spray tent is only 4’x4’, so I’m pretty crowded in there. And I’m impatient to get a thick build so I can clear coat the sucker and start actually playing it. I’ll work on lighter coats. Sphere, that tack coat sounds like a great idea, I’ll try that with my next coat. And I hadn’t thought of using glass—good tip. All in all, after about 15 coats of sealer, primer, and color, I think I’m starting to learn some lessons. It’s about time…. :)
