Great improvement Nino.
For the areas near the pop bumpers, there is the typical pitting in the paint from the years of downward hammering the ball from the pop bumpers. Will you be using the floating type of of mylar ring around the pop bumpers (as per Gottlieb standard), or adhesive type? I repaced mine on the Buccaneer with the latter, after touching up the playfield. I thought in that way, no more dirt getting under the ring.
