The catalyst polyurethane paint used on Lazy Daze is not Dupont Imron. It is manufactured by Cardinal Industrial Finishes, 1329 Potrero Ave. South, El Monte, CA 91733. Imron was one of the early catalyst polyurethanes to be used widely on custom autos and boats and as a result, that Imron word is almost becoming a generic description of that type of paint. Dupont would not appreciate or like that, though. Dupont Imron is much more expensive than the Cardinal paint.
Any repaint must include taking the existing finish completely off and scrupulously treating the substrate, be it aluminum or steel or fiberglass.
Alodine on aluminum and metalprep on steel are two materials I've used with success but on either, the treatment must be done 'by the book' to prevent repeated failure. Not only the prep but also the environment that is maintained while the total paint repair is accomplished is critical. It must be maintained within specific temperature and humidity tolerances. I've seen paint failures because a vehicle was removed from the paint shop when partially painted with some primer exposed and then run back in after masking for paint of a different color over the remainder of the primer.
I've had one side panel on our LD taken down to metal and refinished with a catalyst polyurethane paint system and decided to have the shop use the brand of paint they were most familiar with - which was neither Imron nor Cardinal. It matches just fine.
Using the Imron system: The criteria for painting aluminum was always; an acid etch/wash, followed by a wash with MEK (a solvent) then a primer coat of zinc chromate. Primer surfacer was applied and lightly sanded. The buses were blown off and wiped clean with tack rags before painting.
The Imron had to be mixed completely and set aside temporarily to start the reactive process. One of the main painting requirements was the absence of water in the air lines, a dust-free environment, (a special stickifier was sprayed on the paint shop booth walls and floors), and temperature & humidity settings that followed the guidelines on the product. This was due to the fact that it's almost impossible to "fix," problems with Imron, once it's painted and cured.
Hope this info may help out, ask to look at the paint booth while you are at the Mothership, look to see if the standards and housekeeping I mentioned are being followed.
