Quoted from dmacy:Here’s where we are. Started with 220 and then to 320. This makes a mess so wonder how those do this in their homes. You will need to pull the wide and rear rails as the hardtop fits under.
At this point it’s still less work than a playfield swap but prepare for a mess for the sanding.
You need a random orbit sander that has a hookup to a dust extractor, like this one I bought explicitly for my FG restoration.

This absorbs 98% of the dust, basically eliminating the dust issue.
