Some "Ultrafine" work........

These details were finished out with my new bottle of 3M Ultrafine (fina) and a rotary with the 3M blue pad designed for this polish. The Ram was compounded first with #105. Both were topped with Opti-Seal.......my new favorite.

The next one didn't turn out yellow but you can see the sharpness in clarity.

These are camera phone pics. Sorry. I think you can still tell why I'm bragging on these products.
 
Ultrafina (Ultra Fine) is a great final step polish. Just be careful as it can fill on some paints IME!
 
Cars look great Justin! Toyota/Lexus solid black is great paint to work with.

Yeah, I've seen alot of people get bit in the arse going right to UF right after 105/cutting pad correction on a dark colored car. It may look good when finished (even after a IA wipedown), but the chances of filling are really high. I like following with UF after I get the swirls removed 1st. I used UF with an orange cutting pad to see if it would remove a scuff on my wife's black minivan and it looked great for about a month before slight halos came back. The fillers are actually pretty good.
 
Sure they do. Test it by buffing a black car with a cutting pad without doing a IA wipedown or LSP. Each one could/will expose the swirls in different time lines. Some polishes, even after multiple wipedowns, won't immediately show defect return. That, to me, qualifies them as having better filler qualities.
 
I agree with David

Every polish that uses oils or polymers for lubrication will 'fill? surface marks with paint (and / or oxidation) and polish debris that are not removed will mask defects. If you don?t remove the lubricating oils with a wipe-down then you are by passing the post polish inspection and the oils and etc that are left behind will mask the defects.

1.Some polishes contain specific products (i.e. Kaolin (china clay) or Diatomaceous earth) that are formulated into the product to (a) burnish the paint surface (b) mask surface defects not removed by polishing (evidenced by excess dusting) (c) or to bulk up the product; this type of filler will also be removed by the IPA wipe-down(s) process

2. Abrasive polishes once they become micro sized by friction will fill the micro fissures in the paint, acting as a filler; a simple wipe with a towel will only help to evenly spread them. This can be alleviated with a IPA
wipe-down(s) process

I should have asked the question "why do certain fillers..."

I agree you and Jon, I was just wondering what the difference in the chemical could be that would allow one to fill/last longer than another.

thanks

Difficult to know for certain what chemicals are used in a speific polish / compound, but if a strong solvent is used with Kaolin (china clay) or Diatomaceous earth it will permeate the urathane clear coat. Dependant on how thorough the wipe-down process (i.e. two or perhaps three) they will remain and then be covered with your LSP
 
I have a black Is250 coming in for a paint correction. Right now it hurts the eyes to look at. I like the way yours came out. Great job Justin.

Thanks all for the compliments. I too have heard that UF can fill and then suddenly the swirls reappear. What do you do??? When should UF be used and how?

The thing is, my customers live in a harsh enviroment. Tons of unpaved, gravel roads. Construction. Trees. Plus, we have to drive 5-10 miles just to get groceries! Not the boonies.....but close. It's hard to keep any swirls away. Even with the strictest regimen. Most of my customers want clean and shiny. 2-3 hours work is the most the paint sees here.
 
I use UF as a last polishing step after the finish is just about swirl free. That's pretty much how 3M markets it; as a Swirl Eliminator.
