The white guitar phase 2

It's been an interesting day.
I started working on the finish touch up and it took a few interesting turns. There are numerous chips in the finish that showed up shortly after the original spray. I figured that some flaked off from rough handling of too fresh paint but when I went to working on them, something more sinister occurred.
First, the chips began peeling when I was working them with sandpaper and the white paint started coming off like this.

For some reason, the white didn't bond to the sealer coat. The only good news about that is the white coat came off super easy. :facepalm: Im not sure what happened to keep it from bonding. I sanded the sealer coat to 400, which is pretty smooth, but paint should stick to 400. The white spray was $6 a can "white lacquer" from Ace. Maybe that was the problem.
Anyway, not to take any more chances, I sanded the sealer coat with 180 to get all the remaining white paint and scratches out then hit the whole thing with Dupli-color filler primer. This stuff is thick but I wanted some coverage to make sure everything gets nice and even.

Do you think the sound is going to change with the paint job?

Given that I've carved away some bracing , cut two giant spaces in the top and drilled holes in the bridge block, yeah. :grin:


Oh, an this will definitely change the tone. One thing I've always wanted more than anything was a yellow guitar. Since I'm liking this guitar an plan to keep it, I decided to go for it.

Foo also gave me an idea for a headstock logo.

And I think I'll put something like "EGX-13" on the truss rod cover. :grin:

I can't in all seriousness put some kind of advertising type logo headstock using a made up name. I'm not in business to make guitars and I have nothing to advertise up there. Acme seemed perfect. @Foo always comes through in the 9th.

And Acme on the Warner brothers cartoons often used silly name/number designations like the good old Illudium Q-36 Explosive Space Modulator and all, so I picked E(electric)G(guitar)X(experimental) -13(year of construction)

Seems stupid enough to me.

What causes that?

It looks like it was hit with stripper, but it was just paint. All I can figure is the cheap lacquer didn't adhere to the base coat. I've never had a paint not stick to a 400 grit base before, so I'm not sure exactly what caused it.
I'm going with "cheap paint sucks."

thats what one of the pedal enclosures I painted did. I figured it was because I didn't clean the surface of the metal well enough. I stripped it, cleaned it better and it didn't happen the second time.
 
That can cause it. I don't think that was the issue here, as I scrubbed it with mineral spirits before I sprayed. Lacquer doesn't melt in to shellac, but bonds mechanically. I suspect the shellac was just too smooth for the lacquer to bite into.
I used 320 grit this time instead of the 400, so I hope I don't have a repeat.
