Ultra Hard Sprayable Lacquer?

Hello
Im in search of a extra durable, ultra glossy clear Lacquer or clear coat that can be used in a air pressured spray gun (the kind cars are painted with). I'm making skatebaords and as of now I have just been spraying the boards with a layer of Minwax poly then a couple layers of rustoleum ultra gloss lacquer. Ideally, I would like to have a single quality lacquer/clearcoat that I could apply to either raw wood, or over stained wood as the final finish. Does anyone have any recommendations for something that meets this criteria?

Thanks !

Nitrocellulose lacquer would be as durable as any of the film finishes. You might experiment with a waterbase polyurethane. It's an easy clean-up and you won't have a blushing problem, or as a toxic of a finish. It's as durable IMO, as lacquer. Use the optional catalyst.

how do you think the Nitrocellulose lacquer would handle the flexing wood of a longboard? Our boards can flex up to 2+ inches and need something that can handle that

Look up Varathane exterior water based spar varnish. The more I use it, the more I like it

You are going to have to do some experimenting to find out. It may depend on the ambient temperature when used. N/C lacquer and most clear film finishes are best used indoors. You might consider a spar varnish. They are oil base, and have a high oil/ratio, and UV additives. They will flex, as they are designed to be used outdoors and deal with the elements. But, oil base finishes are a bit tricky to spray effectively.

2 Component Urethane

2K urethanes are very flexible and are usually made for exterior woodwork. U might also want to try a conversion varnish with a 2K urethane top coat.
The 2K urethanes usually start at $100/Gal and go up from there
