Sonax Perfect Finish...

It’s good that I have some of the old and new then! ;) by old I mean white bottle when it was called Power Finish without numbers. I do hate that they keep changing names. It’s an evil plan to make me nuts.

I think the old version was called PO2300 :)
 
So I gave Perfect Finish another go yesterday. Used it with the Flex Finisher after compounding with foamed wool to remove the marring and holos. Worked really well on medium hard red paint. Used a tangerine LC HT pad. I believe I wasn’t using enough pressure on the first few passes the previous attempts to get the abrasives broken down properly. I was just using machine weight. This time I added about 5lbs of force. Finished great on This paint however. Thanks for posting this thread, Mark as I prolly wouldn’t haven’t tried it again if you didn’t
 
Awesome, Jim! Glad it worked better. I got a tip from someone else about using pressure the first couple passes. Really helps.
Sonax directions call for 2,000 OPM with 10 pounds of pressure initially, then speed up to 4,000 OPM with lighter pressure. I do the opposite as far as speed...lol. Works great for me.
 
FYI, I emailed Sonax asking them why low speed with good pressure, then increase speed with less pressure. I usually do the opposite as far as machine speed. Here's the answer I got....

There’s definitely a couple different trains of thought on this. The theory with the low speed, heavier pressure in the first 10 seconds of the cycle keeps the abrasive material intact and “sharper” longer before breaking down and diminishing. If there is high rotational speed immediately the heat build up will break the abrasive down quicker and less up front cutting is happening. So with the lower speed and heavy pressure you’re in effect getting more bite out of the liquid material (polish) then with increased speed the jeweling effect kicks in as the abrasive powder breaks down.

Hope this makes sense but that’s the theory behind it anyway.

I do this with Menzerna heavier polishes.

I don't really use heavier pressure, but slow speed, like 4 - 4.5 on the PC. The idea is to let those abrasive chew at the paint while their at their largest - for as long as possible if I need that cutting power. I may be use firm pressure, and when I back off to light pressure the pad spins faster, furnishing the finish, and breaking down the abrasives.
 
I picked up a bottle of EX 04-06 to compare to Perfect Finish. Not even sure why they came out with a DA version(04-06), as Prefect Finish is better in EVERY way USING A DA. :) Glad I bought 04-06 from Amazon, it’s going back.

Interesting. I’m gonna have to compare.
BTW, Grimeout is awesome.
 
Grimeout is my favorite too! More people need to try Britemax products. Their AOI is special. Almost like a liquid cleaner wax. Great for thin paints.
