really inspiring me. I want to remove the finish from my RG and do a stain too. How does the heat gun method work? I've read that with a heat gun and a putty scraper, you can pry up most of the thick plastic finish. I would love to try, so please let me know.
All in all, your progress looks great. I'd say, coming from a few warmoth strat re-finishes, that you should start with something as low as 100 or 120 and sand until it the color is even,then switch to 180 for a couple swipes, then 220. I don't usually see the point in sanding any higher than 220 grit. But some people say that you should sand to 300 if you're going to use solvent based finish and it makes the finish go on a little more evenly. I usually do water based finishes, so it raises the grain and there isn't a point sanding much past 180 or 220.
What are you planning to do about the green trem cavity? Wait, I suppose you won't see the trem cavity cause it looks like it uses a pickguard.
I have a suggestion for finishes. I recently did a guitar with varathane gel stain and varathane crystal diamond waterbased poly. It was very easy to do, and I think it came out quite well. The reason I suggest this is cause it's really easy to find, home depot has it, it's cheap, it's really easy to do. I'll dig up a picture.
I agree that a dark stain would look good. But if you get rid of the rest of that primer, and the color is more consistent, perhaps any color stain will work. Again, looks good, and keep posting pics!
