I like to use 2 part epoxy to fill in bigger holes. My favorite is RepairitQuik. I got it at Home Depot but it looks like they don't sell it anymore, so I bought AquaMend, It's made by the same company. However to me, it doesn't seem to cure as hard. The trick is to use as little as possible, saves you from unnecessary sanding. This was the first time I used bondo glazing and spot putty to fill in the little holes. Worked nicely, and sanded easy.
The spray paint is Krylon Indoor-Outdoor Gloss Black. I had a can left over from a previous portable. Then to finish it off I used Krylon Acrylic Crystal Clear Gloss. They lied, it's not crystal clear. It leaves a textured finish on black paint. But I like the way it looks.
I have the caps "flattened" on the board and ports removed. This weekend I need to relocate the cart slot and everything should fall into place.... I hope.
Today I decided to wire up the controls. Used some 30 awg hdd cable. Scrap the traces to expose some copper. Tin it and then tin the end of the cable and use some light duty solder and you're good to go.
There's plenty of room in case so I'm gonna keep the original backing of the controls. Avoids using hot glue and the controls will be solid.
