What’s the Best product

[Jhockman]

What products have the best results for cleaning the underside of cars (besides dry ice)?

A little help: overspray? greasy dirt? road dirt? The painted areas? the natural items?

Trying not to cause any damage cleaning years and years of road grime off off my Shelby

I have been using kerosene but not sure if there is anything better for the job
Thanks

I would steam clean first and see where you are at and then move on from there.

Wax and grease remover available at most auto body supply shops will be a little less aggressive

It certainly looks like you use your lift a lot. Is that a TVR Tuscan that I spot off to the side?

I just used varsol and a brush. I had to go over it 3 or 4 times to get it clean though. Here is a picture of how mine turned out. Good luck.

Looks like you've made it a fair amount depending on what you started out with. But the goal is insight. Corners and such use a soft brush if you have to - using these methods you'll likely lose about 20% of the original overspray paint so just understand that is what you give up to get it clean.

What I dont understand after having far over 300 Mustangs that the most unrestored ones I had where black undercoated and just on some edges and corners red what I think was more because the black paint faded away.I know the red oxide was on all Mustangs as it was the base/ primer/ rust protection but how is it coming that the most mustangs have the pretty much similar black protection? Did Ford coated some of these black for the rust belt areas or really the dealerships? I only wonder because a lot of the Mustangs I know have a very similar black coating.

Kent factory examples found here in the US differ then your findings. It seems that with your association of undercoating,painting and red oxide primer that what you are referring to is the paint product and not the thick product usually associated with protective undercoating or sound deadener. With that said the factory paint finish used on the underside is what you are referring to . Possibly how a car is cared for or maintained overseas after the fact may have something to do with what you are seeing. There have been many threads about what is typical for a given time period at a given plant during the 65-70 time period based on corroborated information. That corroborated information and observations differ then your individual findings. I would suggest looking for a different reason why you are seeing what you are seeing consequently.
