I used to own a detailing company for years in NY. Now in Texas.
Why use an orbital? A buffer would have cut better and eliminated most of that wet sanding. I know the newer chemical etching compounds and glazes seem to be more popular but when it comes to paint with that many issues it seems like a lot of extra work.
I recently repaired a buddies truck from extensive trail rash. Took 4 hours but it was rough...
Sorry- just wanting to know your reasoning. I'm old school and had my business through the 90's so I'm maybe out of touch with most newer products. I used Top of the Line products (heat leveling compound and glaze) and finished with wax applied by a Cyclo.
Never heard of that Iron removing product and like that a lot to avoid wasting a good (and expensive) clay bar.
