I finally got a pin...RESTORED AND LOVING IT.
shardian:
I have let the playfield sit for several days before sanding, and still got very minor rolling on the sandpaper when sanding down the playfield with a block. It was minor though, so I didn't get any tearing. I also filled all the inserts with poly. I got a little impatient this morning before work and tried to sand one down. I tore a chunk of the insert clear off almost immediately. Patience is a virtue with this crap. I think the main problem is that the weather is finally changing and it is getting cold (40-50 degrees) at night. My dry times are gonna have to get much longer I suppose.

I also won 6 more CPU boards off of ebay last night. It was a whim purchase of course, but they all appear to have chips intact and were less than $10 a board shipped. Fingers are crossed that I get a few good boards out of the deal. It might end up being a profitable venture.
shardian:
Okay, I have almost all the inserts smooth and level. There are a few that have given me fits, and still have a slight lip. I'll give them another go once the 4th coat of clear dries for a week.
A problem I encountered with the 4th coat was tiny air bubbles in the finish. I never saw them in previous coats, but I had quite a few this time. I figured they would 'pop' after a few minutes, but most did not. I figure I can address these with a stick pin, then spray a bit more when spraying the final coat? I wasn't too concerned this time since I still have another thick coat to go. I still do not like the way polycrylic sprays on. If I had a do-over, I would have used standard polyurethane since it sprays heavier.
shardian:
Oh, I know. I spray really, really thick. I use the light glare to tell when a pass is 100% doused. Just looking straight down doesn't tell you anything - you have to look at an angle to see the reflections to judge full coverage. I still got those pinhead size bubbles here and there though.
shardian:
Sand, then tack cloth, then alcohol with lint free rag, then Naptha right before spraying.
