Thanks to everyone who has posted to this forum, it has been great information. This is a 2001 Saab 93 SE that was very badly scratched due to bad washing/drying processes.

It now has AIO/3 coats of SG/no wax topping.

looks good. post more pics when you're totally done.

Process used for detail:

Had some bad swirls to clean up:

First tired:
3M FI-II with Yellow pad on PC at 3-5 speed, removed 30% or so, of the scratches.

Next moved up to 3M PI-II with Yellow pad (new pad) at 4-5 speed, did a good job of the larger scratches, but did introduce a few smaller scratches.

Then back to 3M FI-II, to clean up the small scratches. This worked very well.

(Not sure that the following was exactly correct, but it did work)
Used 3M SMR for dark cars with white pad. I've heard that when I followed this with Klasse AIO that it probably removed some of the fillers that SMR added.

Next followed up with Klasse AIO with white pad on PC at 3-5 speed. Used the PC until almost all of the AIO was removed. Made the mistake on the BMW to not buff long enough, and it was a PITA to get the AIO off.

Buffed off rest of AIO with MF towel from JTInterprises.

Added first coat of SG with terry applicator pad, learned that MF seems to suck up the SG too much. The terry allows the SG to coat the outside of the terry app to make the applying a little easier. Let SG sit for approx 2 hours, then attempted to remove with MF towel. Found that I had to change MF towels many times or keep folding to new area (maybe a little too much SG, but used less than an oz.). This was a dark car, and looked to haze much more than could be seen on the Sterling Gray BMW, sure it was there just could see it much easier on the Dark Blue Saab. So, followed up the buff of the SG, with a damp MF and then buffed dry with a dry MF. This produced a great shine.

Applied a total of 3 coats of SG with 24 hrs between each coat.

While waiting for the SG to dry added Pinnacle Wheel Gel to tires, also used RaggTopp Cleaner and Sealer (3 coats). Used 303 Aerospace for rubber and Plexus for Plastics. Stoner Invisiglass for windows.

Also when I applied the RaggTopp sealer, there was some overspray, so used Meguiar's Final Inspection to clean this up, not sure if I could have just buffed it off with a dry MF.

Leather was cleaned with Lexol cleaner, followed by conditioner and then Dressing.

Still working on the trim, looks like I got some of the FI or PI, have tried:
Mars Eraser - no go
Shout - helped, but not great
Toothbrush with QD - no go
Finally used a product called De-Solv-It from Orange-Sol Inc. This looks to have removed it, then applied 303 next. Need to wait a few weeks to see if it is really gone.

Well, I think this is enough ;-)

Anyone feel free to comment, as I'd like to learn from any mistakes, or better ways to do the job.

Well, I think that you convinced me to fork out the cash for a PC! Did you have any oxidation that was removed or was it mainly cosmetic sctraches?

Somewhat oxidized, but not too bad. I think the process would have removed a fair amount of it though.

Until I started to read this board, I never knew that I could get rid of the swirls myself. I can say that it took some reading and learning about products, but it wasn't too bad.

One BIG learning I did have was that when you clay, do NOT try to save a few cents by using Clay too long. Cut off small pieces, use them and throw them away!!! I did the top first, then worked my way to the bottom, once a piece had been used at the bottom of the car, it got Tossed! Like most cars, this is where you get the worst pieces of junk picked up.

I think it's pretty hard to determine a car's paint condition just by looking at the photo. You know, different lighting condition, different films or different white balance if you use digital camera, will have different look on the photo.

Sparkling :D

looks great to me
