I'd rather not get involved in this, so I am not going to touch on any of the other issues except this one. I just want to say that I have wiped down cars polished with sip and 106ff with prepsol, prep wash, etc and have not noticed swirls re-appearing. I am not saying it doesn't happen, but when you say "if you deny this it's because you haven't done it", doesn't just make it so. Perhaps, like #80; sip and 106ff might fill when marring is left behind, but if no marring is left behind then there may be nothing to fill. For me, I haven't seen it fill; but like I said, that's just my experience. I am sure I don't have to mention that I've used a lot of it...
I personally don't care who uses what, I use what works for me and most of the time I don't even talk products...just relaying my experience. I do appreciate the interesting conversation you guys are having though.
I agree, great post Ryan.
Question: where are you guys getting the ultrafina stuff? I'd like to try it.
Your right, Picus and I should be more careful with my words, sometimes I get way to interested in the posts. 106ff does finish done exteremely nice and swirl free of course. It could be wiped down and leave a perfect finish on most every paint. However, I have had issues on certain paints, that when the body prep is used, swirls and marring (though less when I started, reappears. Of this is super fine marring that you must be inches from the paint to see).
I have also seen on two cars that I have done (A G35 last week and a Porsche 911) that looked perfect, even after wiping them with prepsol. I pulled both into the sun to take photos of the correction. Both times, I took a break for a couple hours (in the case of the G35, I had to run to the store to get a new EZ-UP canopy) and when I came back I to the cars, I could see minor hologramming that was not visible before.
I think the fact that both these cars where left in the sun (the G35 under a tree, so it had some shade, where as the 911 was left in my driveway) accelerated the issue. With the G35, I did the interior next (I didn't want to polish anymore and was kind of discouraged) then check the paint again. The holograms where slightly more visible then before. Also, wiping the surface with a microfiber revealed light streaking in the areas that where not covered by the EZ-UP.
I had left a black car in the sun (360 spider) for several hours after polishing (but before LSP) and never had the swirls reappear, so its obviously not an always thing, like I stated incorrectly in the post you questioned. I have also never seen this phenomen occur using FPII, though I can't really think of too many specific examples of leaving a car in the sun after polishing.
The 3M 3000 series products are pretty awesome. The Extra Cut compound cuts very fast (its like rubbing an eraser over pencil) but it does leave behind some swirling on the paint, that probably needs two mores steps to correct all the way.
The UltraFina is 3M SRC answer. Its VERY wet and can be worked an incrediably long time. Ryan turned me on to this several months ago, and I remember a video he linked for me, explaing how it worked. I'll see if I can find the link and PM it to you.
I'm not sure where you can get in Canada, but a lot of body shop supply stores in the US carry 3M.
