Bondo Question

[Kickstand Premium Member]

So I have made the pods for my front doors.
Done the fiberglass and now I'm into the Bondo stage.
My question is how high of a grit of sandpaper do you use for the final sand and do you do a wet sand on it.
I read somewhere not to use over a 400 but that doesn't seem right.
I have 400, 600, 800, 1000, 2000, and 3000 here but right now I just finished smoothing it out before I put the second coat on.
If I never see another piece of sandpaper again it will be too soon.

I personally would finish sanding the bodyfill with a 150 to 180 grit. Add more if needed and then use a primer on it to fill in any imperfections and sand marks.
Don't wet sand your bodyfill as it will act as a big sponge and s uck the water down into it.
