start with 80 grit, break it down fast, kind of smooth it out with like 120, ()then a smooth sanding block 320 id say. takes time, but looks sick when done. good luck, later

scuff the hell out of it with 80 grit, and spray it with poly primer to 'fill' the texture. block and primer as needed until its smooth. i typically block poly prime with 220 - 320 then block the final coat of primer with whats recommended from by the paint manufacturer. its a lot of work but its well worth it in the end. remember though, patience is where its at, if you rush through it keep in mind you'll have to look at your mistake. i have a minor imperfection in my dash (that no one has noticed but i know its there) and it pisses me off...its coming out so i can redo it now.lol.

thanks alot guys

I've done it with different grits. If you use 80 you might warm up the plastic and make it stick to the texture then you have a lot more work to do to get everything smooth again. Did that make sence? I just sanded down my air intake and I used 220 grit and it seem to work a lot better.

I worked my dash over until it was completely smooth! I wouldn't go with ruffing it up and then primering over what's left of the texture, I would try to get the best of it out.

2000 Dodge Ram. I shaved and relocated a few things too.

^^---thats really cool how you moved the center vents down in line with the outer vents.
nice dash!

lol sand primer sand is what i did with 220

i'd 180 it personally with a da, then adhesion promoter, then primer, then 320 the primer, then final sand it in 600, then paint.

Ive done lots of interior pieces and they all seem to have good holdout, and adhesion.

I am going to Have to agree with slammedcivic, it always helps to use adhesion promoter. Make sure you wipe your pieces down good with Prepsol(dupont 3919), and Final klean. Just do make sure you get all the grease,dirt,and n e thing used to clean them off... no one likes fish eyes...lol..

do i need to clean them with that prepsol before i start sanding. and when do i use the adhesion promoter?
