I've been thinking about this for a while, along with the whole nitro debate.. Alan once mentioned the chap that finishes an LP top with a tot of lacquer, I've something similar about the folks at Historic Makeovers.
I remember pealing some paint off of my MIM tele, well off the top coat, revealing the sunburst underneath and it was probably 0.3mm, and that's not even including the paintjob underneath, or primer. Then there's the whole story of Fenders and Fullerplast.
Saw a pic posted by the Bvans guys which looks like there's nothing even there depthwise.
Anyone have some further findings on this?
