Old plywood is hard to work with because of planking (visible grain gaps). All areas of the cab show this but there is only so much you can do to hide it within reason and without a TON of work. Here's the front (shot with Laytex Enamel Black). Buy pre-mixed black (I like Lowe's Valspar Brand Semi-Gloss Black $9/qt but well worth it); don't let the bafoon at the home center try to mix black for you.
Wow, that turned out just awesome. Looks factory fresh!
What color/brand did you use for the maroon? Oil base or Water Base paint?
How did you shoot the paint? Did you use a HVLP or Airless sprayer?
Sorry for the million questions, I'd love to refinish my Stargate and achieve the results that you did.
I love Stargate. I miss mine. It was one of the first games I got and I was foolish and sold it. I do not remember why. I made $500 on the deal but I really should have kept it. It was nice and minty, too.
