Castrol Super Clean should have been in the Automotive section, usually in a big box store or auto parts store. The LA's Totally Awesome stuff is usually at dollar stores. Also heard of using bleach, and I generally use brake fluid.
I've only got one really old kit, the 63 Chrysler Turbine. But it's the only way I'd ever get a copy of this kit. No one's re-popping the full detail one now, and the curbside isn't what I wanted.
The orange Toyota Supra from "The Fast And The Furious" for $4 or so. I'm really impressed. It's a nice kit. Gonna ditch the big goofy spoiler and make it look more racing than tuner.
Jo-Han 63 Chrysler Turbine (also one of my favorite cars)

I'm working on one of mine now; 78 Monte Carlo. And I've got another one in my stash but I have to get a body for it; 69 Dodge A100 series van. Unfortunately I'll never be able to build my current one without a LOT of scratchbuilding. No one makes a kit of a 2009 Malibu.
