Dash Painting Tips?

Im not sure what exactly you have planned ,but what I did with mine is I stripped down to bare plastic letting it soak in oven cleaner,scuffed it with a gray scotch pad and primered it.I painted the inside (the gauge face) the best wood like brown color I could find,let it dry,and while it was drying,I polished the lenses.Then I masked off the gauge face(the brown)and painted the surrounding area satin black again.masked off the satin black and painted the trim area a rattle can chrome silver paint(i know im cheap,lol)then I took a fine brush,sprayed some of the rattle can chrome into a cup and brushed the raised areas around the gauges,then used a brush and some white and painted the lettering.It was pretty tedious to say the least,lol.I was going to put some carbon fiber film on it,but decided not to.Good luck
