Here is a reply I got back from 3M regarding filling with SMR 39009
3M PN 39009 Perfect-It Swirl Mark Remover used with a rotary buffer and a
foam polishing pad removes imperfections such as mild oxidation, very fine
scratches, or the swirls left from compounding using a rubbing compound
such as 39001, 39002, or 39004. However, buffing using a rotary buffer
with any product will always leave some level of swirl. Typically the
swirls from 39009 will only be seen in the sunshine. They will very in
severity based on the type of paint, the color of the paint, and the skill
of the technician doing the buffing. A wax such as PN 39526 Perfect-It
Show Car Paste Wax will fill these fine swirls but needs to be applied
periodically to maintain this appearance. Other 3M Car Care products
designed to fill swirls or other fine imperfections include PN 39026 -
Perfect It Show Car Liquid Wax, and PN 39007 - Imperial Hand Glaze.
Thank You for your interest in 3M products
I hope this answers you question.
