Wetsanded the faceplate with 800 and repainted. Still not satisfied with the texture or finish. You can kind of see in the bottom left that there are some imperfections that were made by the epoxy/sanding process. Going to see if I can find some filler putty at a hobby shop to take care of that and a couple other small holes left by the epoxy.
Some more imperfections in the top left corner as well. Hoping filler putty and some sanding will take care of those. This pic also makes it look like there's something funky going on in the upper right hand corner, but that's just a glare
Edit: Supposedly Bondo plastic filler works real well for fabrications such as this. Might check that out tomorrow to make this piece perfect and something I can be proud of.
