how smooth

[nebraskaz71]

Sanding some big interior pieces and I started with 80grit to get rid of most the texture then 120 then 220 I also have 400 and 800 if i need it? There are still a few random spots in small crevices and such that have some texture but I just can't get my hand right to sand it all out without making a mess. How smooth and how much of all this texture really need to be gone for a good body shop to paint this smooth? I mean its like almost complete smooth right now but I just wasn't sure if those few low spots with texture is gonna be hard to cover with some high build or something when they paint? thanks

paint will fill some crevices, as long as you paint, sand, paint, sand it will eventually level out, I can't imagine your dash being that rough, it must be pretty smooth by now.
Just paint a light thin coat, dry, sand, repeat till you're happy
then one more time for good measure.

thats how I would do it anyway...mind you i've never painted a dash, just cabinets for an expensive condo.
my point is I'm not an expert
