Ok, I have this little project, and I need to apply a gloss coat to a painted surface with a brush - do I put it on thick or just enough to cover?
Thin, multiple coats are the way to go. Make sure the surface is absolutley clean as the gloss coat will show off every wart. [:)]
If you absolutely must brush, you probably should test your method on some scrap first, as which you should do will depend upon what paint you are using. Generally, repeated thin coats are probably what you’ll need. Heavy cpoats run the risk of “runs” in the paint, which are ugly. Let the paint dry thoroughly after each coat…
Gloss coat and a brush…Hmmm…Good luck! I know thin coats of varnish leave brush marks. Thicker coats are more self leveling and appear more glossy. (but that’s wood and varnish)
I have an airbrush and compressor if you want to make the drive up Garden of the Gods.
You didn’t say it you’re using a laquer [like Testors GlossCote] or an acrylic clear gloss.
If its laquer, you need to test it on the paint you want to cover, laquer dissolves paint quickly and will leave noticable brush streaks, or worse, ruin the whole paint job.
If it’s clear acrylic, use a nice soft wide brush for large areas and a small flat one for those smaller sections, but first …as in all things chemical, test first in an inconspicuous area for compatibilty![:)]
I know, I know, but between migranes keeping me from working on it most of the month and already having been back to the store twice this week because I bought the wrong stuff, I have untill 2:00 tommarow to have my sons pinewood derby done.
I suspect that it’s an acrylic gloss, as that came with the painting kit and can be washed out of the brush with nothing more than water.
I put one thin coat on already, and it crazed, so now I’ve sanded and back to applying a paint coat - I’ll see if I can get a can of stuff. I could go with a semi gloss made from thined glue ( works reasionably well, and hides smaller imperfections ), but the gloss would make the metalic paint look better.
Isn’t HE supposed to build that?[:D]
Well, when they teach the boys real wood working skills, and supply the equipment to do so in a reasionable amount of time, and the time to do so, then they might be able to say something about it, until then they don’t have the right to demand any kind of compliance.
30 yrs ago, woodworking skills might have been somewhat common in 8 yr olds, but, now the kids are lucky if it’s a part of Jr High school - in some places wood shop isn’t taught until high school.
But until then, my son picked out the shape of the car, and the color of paint, the rest is up to me - who might know just a little more about wood working than the he does.
If you’re going to buy a can of spray, Testors GlossCote comes in a spray can, as long as you spray it on and don’t use a brush it won’t hurt acrylics and won’t turn white like some clear acrylic overcoats. Walmart usually has them, if they don’t then your local arts and crafts store should.
Thank’s but, it makes me a bit nervous using someone elses equipment ( especialy when I never used it before ).
As it is, I figgured out a work around, and I may not need a gloss coat anyway.
I sanded the worst of the crazed gloss off, then sprayed the car with Model Master White Lacquer Primer, once dried it let me see the cracks that were left. I then carefully brushed some thinned down glue over it, and once dry, I sanded some more.
I then sprayed another coat of the white primer on it, once it was dry, I sprayed a coat of Rust-Oleum metalic finish ( shiny aluminum ) and called it a night ( about 4 this morning [:(] ).
After the son woke me up this morning ( about 8:30 [sigh] ) I put a coat of Testors spray enamel on ( Sapphire Blue Metal Flake 1639 ) and then put it in the sun to help speed the drying - once it’s dry, I’m attaching the weights and decals - I may not need a clear coat, but I have a can of Model Masters Ultra Gloss, just in case.
