The "blast of CO2" likely won't get you the pattern of finish cracking that you see on vintage instruments. Vintage finish (nitro) checking mostly follows the grain of the wood...the CO2 blast is more likely to give you a cracking pattern that looks like you threw a rock through a window.

I don't know what the gas is, but the spray can wart removers are cold enough to check nitro. I don't remember where I saw that done, hmmm. Oh, about the checking along the grain. I haven't been exposed to tons of vintage instruments, but I have an old strat that's got a spiderweb finish crack in one of the horns. It doesn't look to follow the grain at all.

peace,

I've got a Gibson Country Western Model from the 50's and an Epiphone acoustic from the 60's. Their finishes are both cracked like you describe. I'll give Co2 a try on some nito'd scraps. Thanks for the input.
