Looked into the epoxy primers, sealers, and automotive grade paints for a Wheelhorse Im restoring.
For me, the cost for what it is being applied to is simply not worth it, especially if you need /want multiple colors.
Would be almost the same cost to tear down complete, send out to sand blast and powder coat as just purchasing the top of the line modern paints, primers, and proper ventilation.
Oh and if you dont also happen to legit spray booth, and a high end spray gun, you’ll be wet sanding and buffing the bugs and orange peel out of the finish anyways.
And for me their is also the hassle of availability, most paint shops have bankers hours around here. Noon to 3 on days with a T.
If your doing multiple pieces of equipment, with the same color scheme, then maybe.
Car restoration - makes more sense, as there will be some value in the end product to the outside world. (Even then unless your a known builder, you’ll almost never recover the costs)
Buy an old garden tractor for couple hundred, spend countless hours restoring it, making mechanical repairs, etc… then take all those costs and double them for the best paint, and your in 5k for something that you’d be lucky to get 1k for. But to the outside world, that old garden tractor will always be just that - well really wont even be that. Will be a riding mower.
2 cents.
