ABS Renewing Spray
by jasonwelsh, published
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 ;)

My brother makes things from various plastics on his lathe (I have some pens from him). He goes through a process starting at 400 grit and finishes with 12000 grit sanding paper on soft back (foam core). There are NO MARKS after he's done. Another method is to use Brasso or Simichrome paste. For small parts I would use Simichrome. I use Brasso to finish my wood rifle stocks and people think I have coated them with glass.
Have you tried with a first layer of prime before giving colour, it can also make the abs look shinny.
