Chris, if you're doing it yourself, go with the Ultimate Compound and Orange Hand pad option as I have suggested. It won't give you the same result as a machine polish, but it may be adequate for what you're after.
Otherwise, have a chat with someone (Jace) around having a machine polish done.
Not having seen the car I can't really make any further recommendation.
I detailed my MPS 3 the other day. Here is what I did
-Washed the car with Meguires Gold class wash and fully dried
-Fully clayed the entire car with the Meguires Clay kit to remove all contaminents
-Washed the car again and dried
-Applied Meguires Ultimate Compound to the roof and bonnet where you can see the rain etching in the right light, I could not find the Lake county Orange pad anywhere so used the Meguires Even coat applicator pad (After this stage the marks were still visible when looked at at the right angle)
-Applied Meguires Deep Crystal Paint cleaner to the rest of the car
-Applied Meguires Deep Crystal Polish to the entire car
-Applied Meguires Deep Crystal Canuba Wax to the entire car
I was a bit annoyed that the rain marks could still be seen on the roof and bonnet after the ultimate compound, Should I retry this when I buy a lake county Orange pad? Or should I just take it to a Pro? Jason how much would you charge to do a paint restoration job?
The Megs Even Coat Applicator is used mainly for waxes, glazes and LSPs (Last Step Polishes). Ie the sort of thing you actually don't want any cut from
I suspect that's where there might be an issue. Ultimate Compound needs something like the the hand pad to work to the best of its ability (you can get them from ZAS via the link I posted in my thread above)
Ultimately though, if you take it to someone like Jason you will get a much better result.
