So I got the quart of "Fawn" lacquer paint for my interior (Dash, doors, etc.) I've never used lacquer before. The paint is dupont and I had to order it. I need to no how to thin it % wise and with what do I thin it with. Any tips on using this stuff or just jump in and paint. I've read that it is sensitive to humidity.

Old School. thin 1-1 to 1.50(thinner)-1
must be thinned with lacquer thinner. easy to paint with, go with thin coats. will dry very fast but if any other type of paint is down can have a reaction. In 64 GM only used Lacquer, if this has been repainted you may want to use a sealer. Do not make to thick will get very hard with age and will crack if to thick. They use to use numerous coats but would sand between each coat.

The dash and trim has never been repainted, I did however sand and spray them with epoxy. The epoxy has been sanded down with 600 grit.

Dupont's laquer was always thicker than most and required a 150% reduction. If possible use a paint grade laquer thinner- some of the primer and gun wash stuff isn't as good and will flash too fast. As already mentioned apply the paint in thin smooth coats and give it plenty of time to dry between coats. Laquer has an infinate window for recoating. You could apply 3-4 coats then wetsand with 800 and apply 3 more for a really smooth finish. You'll need to rub this stuff out for a good shine when it has dried.

Laquer is sensitive to humidity, the higher the heat and humidity the faster the stuff will skin over. If this happens it will trap solvents causing the paint to blush. In extreme cases black cars will turn white while spraying because the paint is drying way to fast holding solvents within. In the old days we would add retarder to slow the drying long enough for the solvents to escape. In extremely hot and humid conditions you just had to wait for a better day to spray :D You won't have any problems if the temperature isn't high even if humidity is 100%

Laquer is forever soluable so be a little carefull applying paint to your dash which was primed with epoxy. If your dash had some original laquer on it under the epoxy the thinner from the new paint might work it's way into the old stuff if you have any cut throughs in the epoxy or if it is thin. If this happens the old original paint will absorb the thinner and wrinkle the epoxy over it. Keeping the coats thin and letting it dry good between coats should keep you out of trouble. Bob

You guys are great! Thanks...

Ive been sanding on the dash and have a few cut throughs to metal and some to old paint. Can I paint over this or should I prime and sand again?

On the bare metal spot you need to reprime them. You can apply a light coat right before you paint the color. Give it about 10 minutes to flash off before spraying color.
On the spots cut to the old paint you can spray new color without repriming.

Ok, so do I need to prime with epoxy? Im out of 2k primer so can I use some rattle can. The spots are very small. Maybe the size of a quarter. About 5 or six in different places. I really appreciate everyones help.
