    Default Red 3M Scotch brite..What Grit?

    I just dropped $$$ for sealer, BC/CC,Clear, cleaning solvent & Misc supplies.
    I'm out of 600 grit paper but have plenty of 3M red scotch brite. I saw it used on the 101 video. can I use that as final wet sand before painting?

    Picture to follow.

    Don't do it! The grit is 360 (US), way too rough for your use.

    I wouldn't unless it's in a jamb area or some other spot that not going to be seen. It's too inconsistent a scratch and may provide an opportunity to put waves back in your nice flat surface. If I knew you were close by I could lend you some paper, but you have no location on your profile.
