Cleaning/Prep Tank Sealant

[Cholley6]

I'm in the process of building my tanks. I have a few spots on my first couple ribs I would like to touch up the fillet and a couple shop heads on the rivets. What is the best way to clean/prep the cured tank sealant before applying more? I'm just trying to get rid of any dust that may have settled on it, especially since I'm not applying a large amount. Should I just give it a quick wipe with acetone?

Acetone will clean it up. Just make sure to get good overlap and seal over the old with the new sealant.

Acetone plus a plastic serrated knife.

I'm not trying to remove any of what's there. Just clean it to touch up a few spots.

don't think acetone is going to take it off; Need MEK for that and even that will take a good bit of soaking to work. It will soften up the outer layer just a bit but won't hurt it.
