D-35's? There is a "vintage" for such problems with Martins from the 1970s...also issues with the Bolteron binding shrinking and popping loose in the waist and around the fingerboard.
The finish companies will often change formulas trying to stay one step ahead of the EPA. Vinyl sealer is one of those products that was one thing and now is another. One of the issues is that the oils in certain woods...Western red cedar, all rosewoods, etc., have a negative effect on the polymerization of finishes, both "traditional" lacquer and modern polyesters. The results are often delamination of the finish to the wood.
Finish schedules are constantly evolving at all the factories I know of, and it's hell staying on the good side of it, much less finding better solutions. This has led me to using four different products for a standard gloss finish: 1) Epoxy pore filler/pre-sealer, 2) Urethane "adhesion promoter" aka rosewood sealer, 3) Polyester sanding sealer, 4) Polyester top coat. And this is if I do not shoot a urethane color or sunburst between steps 3 and 4.
So, yes, it's as hard on the big guys as it is on us, and how would you like to have to pay for warranty work on several hundred...or thousands of guitars?
