    Hello,

    I have two Norlin era Gibsons, one from 95 and a few from the 2010’s

    Have Gibson changed the composition of the laquer over the years or have the formula been consistent?

    As an example my white 1976 Explorer has not yellowed as much as my white 1995 V hence the question.


    Regards
    Henrik

    My 82 and 90 are dark solid colors so I couldn't tell as far as the yellowing goes.

    My 90 is starting to check in the same areas as the 82.....headstock, base of neck, edge of body

    It's just not as pronounced, being 8 years newer. I'd say it's the same formula in that era.

    There's a chance that the formulae have changed from year to year, but I haven't seen anything but random anecdotal evidence that would suggest anything definable going on. I have Gibsons from every 10-year period from 1949 up to 2009, and I really don't see a commonality that would make a difference.

    The formula has probably changed so many times as to have lost count. I'm sure companies back in the day weren't so much of a slave to the current trend of consistent 'upgrades' to sell you the latest and greatest, but the changing environmental regulations over the period would have made for a great number of changes.....some that even Gibson would not have been aware of I'm sure.

    But all of this doesn't even begin to cover the most important effect in lacquer ageing......where the guitar was played, how much, smoke exposure....UV exposure.....temperature changes....humidity changes. These by far will have a greater affect than any nitro formulation.

    This is a good answer and, anecdotally, I've seen plenty of totally yellowed-out white '70s-'90s Gibsons and lots of newer ones that certainly seem to be headed in that direction. I think the tendency for clear lacquer to yellow is pretty near universal across any differences in formulations, regardless of resistance to checking, etc. Like ARandall said, differences in where/how the guitar was stored and played account for the variation from guitar-to-guitar. Your two examples look pretty darned close, color-wise, to me and both are fairly un-yellowed. However you've been keeping, using, cleaning, them, etc. is doing a good job of inhibiting the yellowing process.

    The binding on my 78 bb custom is a medium yellow while my 92 black standard looks the same as when it left the factory

    I would say from my observations that there must have been a significant change in approx. 1971/1972, cause since 1972 the classical finish checking and "spider lines" from late 60s are much more scarce, nearly non-existent and the finishes have kinda more plastic feeling, so they perhaps changed the formula with added plasticizers. :hmm:
