I asked what you had for products and pads to establish what you already have on hand. I would suggest a test spot with 205 and a soft pad first. My experience with that paint has almost universally been easy to correct and 105 might cut to aggressively for what you want or need. From pictures 2 and 4 you posted the marring doesn't look too bad and i would want to gently persuade them flat. You can always resort to 105 if you don't like the 205 test but don't get impatient if the 205 gets you to about 60% corrected. Do it again to get the remaining 40% or maybe switch up to a stiffer pad and do another test spot with it.
One of the things that Mike P. preaches is that factory paint is precious. I never want to remove any more than i need to.
With regard to shelf life of Megs 105 and 205, i have an old bottle of 105 that has turned very watery. Shake the living h*** out of it. I do every time i grab it and it never gets back to the consistency it had when new but i've still used it several times and it works just fine. Good luck and have some fun!
I have never used the Megs pads so can't comment on them. I am a huge fan of the ThinPro LC pads on a DA machine though if you need pads. What machine do you have?
