Hi.
I ordered the Mylar Playfield Inserts from eBay.
I am scraping off the bad inserts and prepping them for the Mylar version.
What grit sandpaper should I use to complete my prep? I used a razor knife to scrape off the old inserts. I believe my next step should be sanding the inserts. But I am not sure what grit is ideal.
Any suggestions?
