Sanding?????

Ok, so I'm gonna start getting my plastic under the hood ready to take by Rich for some airbrushing. I have to sand the clear coat of my existing pieces that are airbrushed so I can put a new base coat on them. What kind of sand paper should I use, and should I wet sand or dry sand my pieces. Like I said I only need to get the existing clear coat off, I dont need to sand of the airbrushing on there now. I can paint over that once I get the clear coat removed.

Thanks bro, I'll give that a shot

And make sure you keep it wet during the sanding process.

Will do, how do I know if I got the clear coat off? Will it be real dull looking?
