You must admit as the pro that you are and the experience you have, paint and materials have come a long, long way since the seventies. As far as I know I don't even think lacquer is used anymore?
Yes, EPA VOC regulations have eliminated the use of lacquer for auto repairs. By about 2000, it was pretty much phased out. I doubt I would use very much of it, even if I could get it. Paint companies were eager to phase it out, because they urethane systems they replaced it, with were much more profitable for them.
With urethane, you can spray it, force dry it in the oven for 30 minutes, un-mask it, and almost immediately re-assemble it. Provided you can master putting the paint on nicely, and getting clean paint jobs. That kind of production leads to good potential for profit. About 95% of shops don't even try to do repairs, without automatically planning to sand, and buff the repair. This is because, they have been convinced, and will argue, it can't be done any other way.
I have zero interest in sanding and buffing anything, (been there and done that), so it is imperative that I paint it, so I don't have to.
Of course, everyone needs to find what works well for them, with the equipment, and shop they have. But then, they should be ready, and willing to adapt those procedures with the times, as vehicles and materials evolve.
There is always a better way to do things, and unwillingness to accept that, is a common costly mistake.
BTW: I'd pay the $250 and get it fixed. You can't fix it properly yourself, for less than that anyway.
No point in paying for insurance, and not using it.
