Select sander and grit for painted doors

this is basically a Shaker door with a profile inside so with the Shaker door that's perfect for the 3x4 because that means I can get in corner to corner right the fastest way that I found to be able to do this is with the 10 mm right the 10 mm is nice because it keeps me up above the wood if I bump the sander into the wood I don't do any damage versus the 5 mm and this the 5 mm is is fine on flights but this is just a better situation for the 10 mil but what we want to do is we want to sand the 10 mil and with a a painted door you want to start with a a fine right we want to start around a 220 grit 180 to 220 grit scratch and the reason being is a factory cabinet usually has a clear coat on over the the paint so we're going to again we need to take that back down we need to get that shiny surface look off of it and we need to put a scratch in it so that our next coat will adhere so
