wow amazing work!
i have a space invaders myself, game is gorgeous, except for touch up that was done on the playfield before i got it.
touch up was done (i guess, pretty sure) with testor paint, not a bad job but no clear on top of it.
so you know what gonna happen.
from what i can see (touch up) mine was in a bad shape before the touch up, but damn... why not protect it? fools!
anyway, still looking for a playfield maybe with less work to do.
as for the clear, i work in a body shop so not a problem for me and won't be my first clear job on a playfield.
again, very well done sir!
