What kind of Finish was Hamer using in 2005/2006?

Nitro?

Poly?

Some mysterious cocktail?

Young Murkat may need to do some finish matching on the Superpro I just got from Coolfeel.

Thanks

I was under the impression that it is a urethane catalyzed cellulose acetate - impossible to 'melt' repair unlike cellulose nitrate.

At the last HFC open house (03-04?) I chatted a bit with their finisher Gary and a couple of the other shop guys. For quite some time I had heard Jol reference something called Urelac and later he would just say nitro. even though Hamer stopped using nitro. 92-ish. Anyway they told me they were using a product from the now out of buisness Lawrence McFadden that was listed in their product sheets as Urethane Guitar Lacquer. It was used as the sealer and topcoats and PPG automotive basecoat paint was used for the color. McFadden's U.G.L. was a catalyzed finish, the tech sheet listed it as a CAB urethane so I'm not sure why they were calling it a lacquer. I actually asked the guy in tech. support at LMcF once why they listed it as a lacquer when it was a urethane product and he couldn't really give me a good answer, just some bullshit about "lacquer like drying times".

Anyway it would be classified as a "poly." even though that abreviation is pretty broad. Since you can't get LMcF's U.G.L. anymore (well you can but the company that bought the LMcF formulas kind of sucks and have a pretty hefty minimum order) any thin, water clear, catalyzed urethane will substitute just fine.
