Where to buy Acrylic Urethane

Whats the best place to buy Acrylic Urethane automotive paint.
Im going with single stage for my goldwing motorcycle, Gloss black, want to make it simple not clear it and rub it out.
Theres 34 paintable parts on it.
Or would you a diffrent paint system?

Kirker makes an inexpensive single stage gloss black. will cost about $70.00 gallon sprayable from smartshoppersinc.com

ua-70330 ultra glo super jet black

I would do base / clear ,but thats me.
also base / clear will cost more

Black is a good color to do single stage.
easy to cut and buff.

You can't beat the price and quality of kirker paint

Someone recently posted good things about the summit brand paint.
