More pics of build in progress.
Painting took way longer than expected, actually everything took longer than expected but that's kinda normal for my projects.
Unfortunately I don't have too many painting-in-progress pics but I followed the general consensus from these fine forums...
Little bit of wood filler, 2 coats of Kilz oil based primer over the MDF, left to dry for 2 days, sanded with 220 grit, 2 coats latex paint, left for 2 days, light sanding with 220 grit, 2 more coats, 2 more days, light sanding with 400 grit, final coat.
Using a roller and paint pad worked out pretty good, I'm sure spraying gets things done quicker but I already covered the garage with a fine layer of MDF dust, I don't need to add a layer of overspray to the mess.
Designs/colors for vinyls on the side/front, control panel and marquee are still TBD. Electric blue T-moulding ready to be installed once I have everything else done.
