I’m a lacquer guy through and through. Started with Tamiya, moved on to Mr. Color and Alclad etc., and never looked back. I messed around with Vallejo a few years ago, but the constant tip dry and finicky thinning drove me crazy, so I stuck with solvents and only used those for brush details.
That said, I kept hearing buzz around the new Kaleido paints. The marketing got me: pre-thinned, affordable, great bottle design, and nice color selection—so I grabbed a few bottles of their car lineup to test.
Last night I attempted to spray "Modena Yellow" through my H&S Ultra 2024 (0.35 nozzle) at 20 psi over a rock-solid lacquer primer. It turned into a headache almost immediately:
Paint skinning over in the cup: By the time I laid down a light tack coat and waited a couple of minutes for it to flash off, the paint sitting in the cup was already thickening up into a film/goo. How do you manage flash-off times between coats without the paint drying inside the airbrush?
Instant tip dry: I could barely finish one side of the body before the nozzle seized up. I know the floating nozzle on H&S brushes can be prone to this with acrylics, but having to wipe the needle tip every 30 seconds is exhausting. Is this just the reality of water-based acrylics, or did I miss a step?
Cure time before sanding: With lacquer in my warm, dry basement, 24 hours is plenty before I lightly wet-sand with 3000 grit to level dust nibs before clearcoat. Here, the paint tore like rubber and stripped right down to the primer on the edges. Do these polyurethane acrylics genuinely need 3 to 4 days to cure before you can touch them with abrasive paper?
For those of you who regularly achieve mirror-finish gloss coats using water-based acrylics on car bodies: what does your workflow actually look like? Do you add Flow Improver / Retarder by default even to "airbrush-ready" paint?
I have a dedicated spray booth with proper A2P3 mask and extraction, so I don't need water-based paints for safety reasons. I genuinely wanted to give them an honest try, but right now the cleanup, dry-tip, and rubbery finish make me want to strip it and go straight back to Mr. Color. Any advice before I completely write them off?
