Painted the dash today......right in the car. Here's how:
1. Masked all the surfaces, using a combination of painter's masking tape, brown paper, and plastic dropcloths. This is the whole job, in my view. As carefully as I did it, I still got some overspray on the windshield.
2. First coat. I am using a flat black, actually some high temp engine paint I had left.
3. Final result. Uneven gloss is from uncured paint, I expect it to even out in a few hours.
This ought to lower the glare some, since it was a faded grey-white to start with.
