You can use a light degreaser in place of clay. I like Simple Green cut as much as you can to still remove the cosmoline. IronX is also useful, even on new cars to remove ferrous buildup from rail transit.I think the clear is on the soft side too. I will end up doing a full paint correction on my new GTI once the weather warms up. They did not even get all the plastic adhesive off. I already had to take a clay bar to 20% of the car, it felt gritty in a few areas.

Sure, it isn't "great" for paint, but it cleans off cosmoline and preps the paint for a proper polish and sealants. Just as many use isopropyl to thoroughly clean, this is a milder approach. But I also use a rotary, on single stage black paint, so I'm one of those.Simple green is a solvent+detergent and isn't great for paint.. and especially bad for use on aluminum. Use an automotive cleaner like Optimum Power Clean. That said, it's chemical decontamination not mechanical, and like IronX or similar products should be a step before mechanical decontamination (clay). But they won't get everything clay will.
