Please don't take any of this the wrong way but it appears you could have worked the M205 a longer to help get rid of that micro-marring. You can see it in the photo of the hood and in the shot of the tailgate where the sun is directly reflecting. …..good photos by the way which help show the true condition of the finish (which in turn can help folks with the advice they give). Shots in the shade or without a direct point of light are fine for showing some reflectivity, shine, etc. but not for highlighting blemishes (or for showing how blemish-free a finish is).
The shot of the hood also shows a couple of RIDS (random isolated deep scratches) that appear (in this case) as long, straight scratches. Those I wouldn’t worry about too much and will likely take more work with M105 or a different compound. However, all of those short, swirl-like scratches could probably be eliminated with more passes of the M205 and possibly a more aggressive pad depending on what you were using. Some or even most of that more minor marring is likely the by-product of the M105.
If you like M205 and want to try something more aggressive with the same ease of use, I would pick up some Meguiars Ultimate Compound. It finishes quite well for a compound IMO when applied via DA. ….so well that some won’t even follow up with a finishing polish (I do however). If you get some time, do a test spot like I described earlier on the hood (masking a small area) so you can see if it will be worth your time re-doing the whole vehicle. I get the feeling the M105 perhaps got the better of you and you were not able to devote the time/effort you needed with the M205 to get the most from it. M105 is not as easy to work with IMO/IME as some folks may suggest. There are those like you on the various detailing forums who have expressed similar concerns. I too find it a little finicky.
I hope you find some of this helpful.
On a side note, the following is a photo after just using UC on my 2010 Challenger (YMMV depending on a number of variables). Not the best shot but hopefully it’s enough to give you an idea:
Even if it finishes out well, I still think UC leaves the finish a bit cloudy which is why I still use a finishing polish. These pics are a couple of weeks/washes after the car was finished using M205 and a sealant (Wolfgang DGPS 3.0 IIRC):
The paint on my Dodge is what I would say is on the hard side of medium compared to hard clears like some of the GM’s I’ve worked on and super soft paints on something like Subarus. I’m using a Flex 3401 VRG DA which is more powerful than the more popular Griot’s, Meguiars and Porter Cable offerings but the same results can be achieved with those. ….the Flex simply works a little faster.
fyi... I'm going by memory but the first shot I believe was taken with a point & shoot Canon Powershot and the last two were with my Canon T2i which is why the others may look more rich. No post-processing enhancements (like HDR) were made to any of the photos.
