Vid,
I so thank you for taking your time and giving us your professional tips.
I have encountered a Firepower playfield which was coated with Varathane from the get-go. Also, the previous owner had removed the 2 star rollover buttons but cracked maybe 2 fingers from each insert.
This can be a great candidate to practice clear-coating my first playfield.
Questions:
Can the Varathane be removed off the playfield ?
Using your "don't pop inserts out" option, can the broken rollover insert be salvageable ?
