you're right about the skull area, although I found a better way in doing it. Mind you because I haven't done it for a long time, I've forgotten, so it'll be fiddley and then when its all over, I'll figure the easy way again. Always the case. Although I may have it on video, gotta try and track it down.
I will remove as much as possible, but you are right about worrying to remove the playfield. I figure its a major job, however, I'll have a careful look at it now seeing you reckon it's not that major. Since being on these sites I've done things that scared me shitless before and now they don't bother me.
I think its the "how much will it cost to fix the stuff up" or even worse can it be fixed after I've screwed it up. I've found most things aren't that tragic, parts seem to pop up here and there etc etc.
BTW the shellite, is it used to remove the residule glue? I read people in the US use GOO GONE then do a final clean with napthane/shellite. Did you ise only shellite and elbow grease?
Goo gone can eat into the paintwork if let on for too long, some people apparently use it without any dramas, but shellite works fine, is cheaper, and no risk.
