Sounds like waxing nostalgic about lacquer. While in some instances lacquer may be superior, urethanes far out-weigh it in overall quality. Lacquer can be surfaced flatter in one step, blends easily for repair, and yes, is simple to apply. Durability is out the window. It`s brittle, scratches and scuffs very easy, and does not hold up to road abrasion. Urethanes rule in durability. It takes hours of surfacing to get it mile deep, but worth it for the rest of the equation. Syphon feed guns are ok for quicky work but waste mat'l. Gravity and HVLP guns do indeed put it on the part. NOT ALL GRAVITY GUNS ARE HVLP. Be certain to check all the specs of any gun you may purchase. Devillbiss, SATA, Cobalt, all good names. Cobalt being the lesser priced in some applications. Spray guns are like a carpenter's hammer. Every painter has their best choce based on years of practicing their trade. Base your purchase on how often you plan to use it too. If your doing 1 vehicle you may not need a $500 SATA.
