MK37's Coating Prep Polish - why so much?

[Bunky]

I was looking at MK37 products and saw a Coating Prep Polish and noticed it had a price of $34.99. This seems a lot for what seems to be what has been called a pre-wax cleaner (if abrasive it was due to pad selection). It seems like the trend is just to use products like CarPro eraser to supposedly remove everything. I always these polishes because they can remove water spots, etc. that Eraser could not touch when not doing a correction. I would think something like Poorboy's Pro Polish could do the same thing.

MK37 description -
Polishes and preps paint for coatings, waxes and sealants - no IPA or paint strippers required! McKee's 37 Coating Prep Polish is a non-abrasive chemical polish that deep cleans automotive paint, ridding it of below-surface contaminants that will prevent a coating, paint sealant or wax from properly bonding.

That sounds like it's a "primer polish", which is definitely not like Poorboy's Pro Polish. Primer polishes have no oils that could interfere with the coating bonding. Some polishes in this category would be the Dr. Beasley's NSP's, Labocosmetica Fiero, and Gyeon Primer.

I’m on my 2nd bottle of it… What’s always made me wonder is how it tends to make a white pad turn almost brown as if it’s doing a mind blowing job of decontaminating the paint [even happens on white colored vehicle] even when there’s no way the paint could be That dirty.

Paint could be washed, clayed, but somehow this polish turns a white polishing pad in between egg white to a hint of brown.

1 day I’ll get back to testing what’s really behind this.

I have a bottle of Auto Finesse Prep Coat and it does leave something behind. I just followed with Carpro Eraser anyway. I read the Gyeon Primer description and it does leave behind something. AF left the surface slick too.

Even if I used PB's Pro Polish I would follow with Carpro Eraser.

I sent an message to Nick at MK37 and will see what he says. It says it leaves nothing but Primer and Beasely's do in addition to being a very fine polish.

Agree this sounds like a Gyeon Primer or CarPro's Essence, yet the lack of abrasives does lean towards Pro Polish.

Without abrasives, I'm not sure why someone would use it. A good polish will correct the surface better and probably bring up any contamination just as well. I'd use one of the "primer" polishes if I was to go that route.

If a car has been neglected for a long time, I think there will still be grime buried deep in the paint. Mechanically polishing is really the only way to get it out. I know on several of my own cars I've bought used, I done a deep cleaning wash, clayed and when I polish them my pads will turn a dark from the crud they are bringing up while polishing. You're probably seeing additional cleaning.

Long ago, Mike Phillips did a post about this here on the forums. He had some great pictures of a bright yellow hotrod. After the wash and clay, the paint looked pretty good. However, when he did a 50/50 on the hood the difference was pretty striking. The gloss changed as you'd expect from removing the swirls, but the color difference was the biggest change. The un-polished side looked dingy and had a gray tinge to it while the polished side was a much brighter, "true" yellow.

I hear you, however the white vehicle I’m referring to belongs to my immediate family and was purchased brand new in 2014 and I’ve been taking care of it since day 1. It’s been neglected recently in the form of me not washing it as frequently as I should, but years ago when I did that test with the McKee’s it was so well maintained that I hadn’t ever polished it yet because the paint was still perfect & virgin which is 1 of the main reasons I was using the Coating Prep Polish and that’s because I was pampering that virgin paint to the point where I didn’t want to use an abrasive polish because it didn’t need it.

Still to this day I haven’t polished that entire vehicle. I intended to about 3yrs. ago but didn’t make it past the passenger door when I saw absolutely no difference being made so I left the rest alone.

Once in a while I’ll hit it with some iron remover and claybar it, but it still hasn’t needed a polish. Being pearl white helps it as the main important thing is keeping the paint gleaming clean and smooth, which it is.

Maybe I’ll re test it soon.

My questions are now:
1. does it have any abrasives (not mentioned) or just chemical. PB Pro Polish has no cut but it can be used with various pads to be a pad dependent polish. I am looking for the function provided by what was called pre-wax cleaners without needing the second wipe down.

That is, with a finishing pad will it remove light water spots and other bonded stuff wash and sprays do not do.

2. assume it leaves nothing behind like Gyeon Primer. Primers leaves a SiO2 layer behind but needs 24 hr cure. Gyeon says you can remove it with prep spray if you plan to coat immediately,

Gyeon Primer and Essence are a little confusing, Primer doesn't say it leaves nothing behind, it just says if you wait 24 hours you don't have to do a prep wipe...except probably if you are letting the vehicle sit for 24 hours you are doing to want to do a wipe to get any dust off. Essence says:

"Theoretically speaking you could skip use of Eraser if Essence was properly used via machine BUT it is hard to measure if you polished the lubricants in the Essence down far enough and so we do recommend using Eraser to be 100% safe. If possible, wait at least an hour after Essence before using Eraser."

Labocosmetica Fiero says you can go right to coating, but I thought I had seen somewhere to wait a half hour, unless that was the Dr. Beasley's.

I feel for you that the "pre-wax cleaner" products that everybody made seem to have disappeared. I guess these were in the category of "chemical cleaners" that didn't really have any abrasives. You can still get Klasse AIO, that was certainly an old standby. There's also this Duragloss product: 1060 '-' Squeaky Clean Surface Prep 4oz '-' Duragloss

I use it for people that don't want paint correction but want a gloss enhancement followed by a coating. I can get around a decent sized vehicle in an hour, shine it up and go straight into coating. I've got a job like this coming in tomorrow. The guy's bringing me his girlfriend's car to coat but she could care less about scratches. Saves him money and saves me a nice chunk of time. It's a win/win situation.

I like 3D One for ceramic prep.

I do this as well. New vehicles get it also for when there is no correction needed. I have had gyeon primer polish remove rotary haze after cutting step. Mind you if your going real hard on cutting, then ive had it not give the results that 3d 520 does.

Either way great product and i use it before every coating
