So, I'm going through the posts now. On page 3 and decided to use search function in thread for "Zaino". Showed 3 hits but the first 2 results had no mention of Zaino.
Anyway, thoughts on this product for the playfield? Put a few coats of this stuff on a car and it will last 6 months and still have water beading up. There are different versions some with no abrasives.
It's one of the most popular non-commercial waxes available, before the whole new ceramic coatings became the thing.
