great example of the oils in polish being washed off'ed.
Well for one, if you work them long enough, the oils are all broken down (3.5 to 4.5 mins each is what I spend) and I don't finish with that.
I start applying others by hand such as Glare Micro Finish and Pro polish which will prepare the surface for sealing and then a coat of pro polish again seals it
I can't use IPA on them cause the fillers will be removed
So because I don't use IPA with the Glare, the fillers get locked in and the paint protected and the fillers never come back out
My usual regime is full correction and extreme at that where I will do three to five steps by machine (last is 106ff usually) then two to three steps by hand with either Driven to Perfection Auto polish applied twice (1 x as a polish, 1 x as a sealant), the Glare twins, Permagard Severely and PD5000 (same result as glare twins) , Toughseal step 1 and 2 or Ultra Gloss superpolish and Prima Amigo then sealed with something else
There are no fillers in any of the Menzerna polishes or the Prima bundle either and so when broken down fully and burnished at 600 to 850 rpm for that many minutes, the oils are pretty much gone or well broken down and then the next two to three hand applied products will remove all those oils completely.
perhaps if I was to just do a two step with SIP and 106, then yeah I would probably IPA just to make sure but I don't do that very often
Most customers of mine want two to six coats of sealer applied so I have the car for two to five days.
