Help out a noob with a few PC questions

[Gopher]

I recently purchased a 2003 BMW used in titanium silver. It looks good with only a few little scratches here and there, but after discovering this site I realize it can look much better. I plan on doing a full detail on her in about two weeks and want to make sure that my process is not misguided...

I'm planning to do the following:

Prep:
Wash (meguiars soap, a tiny bit of dawn and some vinegar for water spots)
Possibly clay (I clayed about a month ago)
Wash (meguiars soap & cap full of AIO)

Polish:
3M Machine Polish w/ Meguiar's 6.5" foam cutting pads (W7006)
- I realize this isn't a very abrasive polish, but I only have one scratch that I think may be difficult.
Klasse AIO: Meguiar's 6.5" foam polishing pads (W8006)

NEED HELP HERE: I'm undecided as to the next step. I will have some SG on hand, but I understand it is very difficult to work with, and I'm leaning towards using an alternative sealant. Proper auto care seems to recommend the spray "Menzerna High Gloss Acrylic Sealant" and I suspect using that would be MUCH easier--Do you guys think this would be a good substitute? I initially planned to use Menzerna products the first time, but got a really awesome deal on a package with the Klasse (Porter cable, 3M machine polish, AIO, SG, 2 cutting/2 polishing pads for $80shipped).

Questions:

1. Is my process OK?

2. What speeds should I be using for the polishing/should my pad choice be fine?

3. Should I bother claying again before this process? (bare in mind I do not have a garage).

4. Is the spray on Menzerna sealant going to be a good substitution? (I can always SG it in the future when I'm not fatigued from a long days detailing/get a little more comfortable).

5. Do you guys feel this will yield good results on a silver car? I've gotten it to look pretty wet in the past and am hoping this process will maintain those results a bit longer.

Thanks in advance, guys!

Well, I decided to check out the Jeff Werkstatt AJT spray for my sealant as I've come to understand people are having great results with it on silver.

I'm still curious about whether my process and pad choices are correct. Additionally, I'm wondering if you guys would bother claying again so soon.

Thanks in advance for any feedback.

Claying definitely won't hurt, go ahead and do it.

I'm not very versed in 3M polishes, so I can't judge you there. The JW sealants will produce fine results on silver, and it a good choice.

Polishing is generally done at speed 5/6. Use 3-4 to spread the polish out, and then kick it up to 5/6.

I'm sure these will yield fantastic results. Don't forget to post pics!
