So recently I have been on a quest for a sealer that will make ABS look amazing after you file or sand the ever living crap out of it.

I like to sand harsh 90 degree corners on personal handheld products like the phone cases and Arduino labs. The problem is it leaves sanding marks.

Also ABS glue leaves behind a shinny look in areas that does not look pleasant.

I bring you more of a public service information than a Thing-A-Ma-jig.

Other clear coats just do not even cut it or feel sticky after awhile. These do not!

Both products work about the same except I like Valspar frosting much better.

It dries so fast! and covers the most aggressive tooling.

Valspar works on PLA also. Rustoleum FAILS on PLA.

See attached photos of test.
I hope you enjoy the tip ;)

Tool your product.

Spread ABS glue anywhere on it.

Wait till everything drys and spray the Renewing spray of your choice.
