Looking great so far!

Block-sanded the initial 4 coats of primer (acrylic automotive). It will need some lightweight body-filler to eliminate 3 small imperfections that I have discovered on the sides. I spent a couple of days rounding over the edges that lead into the various cavities, which reduces the risk of sanding through very sharp areas, you can see there are no actual 90 degree edges anywhere.

I'll then shoot 2 more coats of primer for a total of 6. This will give me a flawless base to star the colour-coats.

Wow John, your attention to detail is amazing. This is going to be another stunner I think.

While not a delay just yet, I am struggling to come up with a plan to spray the finish coats. I had been working through ideas around a small spray booth in my garage, but this requires an exhaust fan, and I cant find anything suitable for less than twice the budget of the whole guitar to date.
I've seen people use simple house fans online, but I'm convinced this could lead to an explosion as the vapours pass through the fan housing. Not using a fan would create a cloud of overspray. I primed the body by spraying it in the backyard, but the neighbours aren't going to tolerate that for very long.
Anyone have any exhaust fan cheapo solutions?

HI Moose, if you look at the videos that Adam has done, there are a couple by forum member Jarrod who demonstrates how own booth, which instead of a fan has running water in the back of his booth to catch the overspray! Very self contained, and there is also an exhaust in there if he so needs it, so that can be added later on. Maybe even try a blower fan to PUSH the overspray out of the booth?

For what its worth most household exhaust fans are shaded pole induction motors so there would be no sparks to cause vapor ignition

I've had a good bit of advice from work, get a 12v power source and run a marine bilge blower, they are built to withstand petrol and diesel vapours, and can shift a fair bit of air.

I'm pulling the pieces together now.

Ok, I've built a spray booth. It's plywood, with a 500mm2 opening in the floor into which a spray booth filter fits. The bottom section is a sealed box, and on the side will be a 100mm high flow, explosion proof bilge fan from the marine store. This is powered by a 12 volt bench top power source.
I just need to cut some plexi glass for a 2 piece hinged top.

Nice John...Knowing the finish on your last guitar, I can see these going into mass production soon!

My booth has an industrial extractor fan (this is a must)for removing over spray and paint fumes. The problem with having an extractor at the bottom is it pulls dust and other floating matter straight on to your guitar. Better to be at the top so it pulls the crap away.
