Last couple of days have been busy. First up was to clean off the backglass. I had removed the paint using a razor blade, but that didn’t seem to work on the gold layer that was right next to the glass. I started out trying to use common household cleaners, but it turn out that the scrubbing pad I was using was causing a haze on the glass. After trying every cleaner I had in the house, the winner was Cerama Bryte. It got rid of the gold without scrubbing. The trick was to spread it out, and let it dry. Then rub it off with a paper towel, and the gold fell right off. Reading the back of the bottle, the active ingredient is citric acid, so there are probably a ton of different cleaners that would work.
So at the same time I was working on the backglass, it was time to work on clear coating the playfield. I used an xacto knife to cut out all the holes in the playfield. I’m using the two part auto clear and brushing it on with a foam brush. Of course it has really nasty fumes coming off it so you need to wear a respirator and swim goggles. I ended up putting four coats of clear on it. I mixed up 3 oz at a time which is good for a single coat (2 parts of the clear, and 1 part of the activator). I followed Clay’s directions and went from the right side of the playfield to the left, then turned over the foam brush, and immediately went back. I worked from the top of the playfield to the bottom of the playfield. Each coat takes about 10 minutes all said and done, and then it cures for 4 or 5 hours before another coat can be applied. I did the four coats over a two day period. Clay warns that you can’t wait more than 24 hours because it cures so hard that the next layer can’t adhere to the previous layer.
I then applied the vinyl to the backglass (it is white vinyl that is normally applied to the inside of a window). Used the wet method again. I bought the vinyl from Banner Buzz and after shipping there were definitely some “crinkly” places in the vinyl because the backing paper being applied and rolled tightly into a tube. Even relaxing the vinyl for a full week didn’t help it. It might be that fact that the only way to get it perfect requires you to buy it locally. The price for a local print vs a print from India is pretty big. I paid about $65 for the art, and locally, I’m sure I would have paid about $200 for the same amount of vinyl. Finally the backbox and cabinet were reassembled. Here are pictures as it currently stands.
Tomorrow looks like it is time to wet sand out the clear coat, so reassembly of the playfield should be happening either Thursday or Friday. I really have to start coding some rules soon.
