Dash Paint Question

[Marshall V. Daut]

And it's not just the portion of the gas tank facing you that needs to be painted. The gas tank rolls underneath towards the firewall. This is a tough area to spray even when the body is off the car and without anything in the way, such as the steering column, shift lever, e-brake handle, and cowl panels. And as CT Jack states, you've also got a cloth interior and upholstery to protect from overspray. If spraying Model A and T Fords as a hobby since 1983 has taught me anything, I've learned that overspray is an insidious element that finds its way to any unprotected surface, even where you wouldn't expect it. Use a heavy mill plastic tarping, not the thin stuff because paint filters through that. Then cover the plastic with cloth drape lengths. You'll have to be creative in masking off the headliner. Keep the spray gun pressure as low as you can without creating orange peel in the paint. That can be sanded and rubbed out if necessary, but you also run the risk of sanding and/or buffing through the paint.
What you propose to do can be done, of course. Just take a lot of precautions and you will succeed.
