CMC Detailing-BMW Z4 M Coupe

A friend of mine recently talked his Dad into trading his Hyundai Genesis in for this low mileage M Coupe. This is a car I've always had a thing for, so when my friend asked if I could detail his Dad's new-to-him car, I was pretty excited. And I made him a deal...help me from start to finish, learn how to care for it, and the detail would be on me. This M Coupe was in pretty good shape, although it had some repainted panels, rock chips, shoddy touch up in one spot, and one REALLY ugly scratch.



We got a late start on this car, around midday, and only had a few hours to do what we could with it. He mostly wanted to see if I could remove the large scratch......I couldn't. It was fairly deep and wide, so I could only do so much. Even if he'd had touch up paint, the color and metal flake of the car would have made for one really obvious repair. :frown1: We decided due to the color, condition and time-frame, a one-step would be the best course of action.







The car was 3 days from the dealership, so it was relatively clean to begin with. It had decent shine, leftover wax around emblems and panel gaps, and a clean (non-greasy!:woot2:) interior.



Process:



Wheels: Sonax FE

Tires and wheel wells: Optimum Power Clean 3:1

Foam and rinse: Meguiar's Shampoo Plus/Dawn

Wash: Optimum NoRinse

Clay: Clay Magic Blue

Clay Lube: ONR at QD dilution

Windows: Meguiar's D120 glass cleaner

Exhaust Tips: Meguiar's NXT Metal Polish (I refuse to spell it "Polysh". That's just stupid. :nono:)

Polished: HD Uno on Meguiar's MF cutting pad/ GG6 DA/ Meg G110v2

Wheel sealant: Chemical Guy's Factory Sealant (Got on trade, trying to use it up!)

LSP: HD Poxy

Door Jambs: Optimum Car Wax

Tire dressing: Optimum OptiBond 1:1





As it arrived: clean enough, but could use a little work. I apologize for the overcast pics, not much I could do about it.

Cleaned the fuel filler door with OPC 3:1, then foamed and rinsed the car, and brought it inside for the rinseless wash.

There were some obvious spots where it was repainted. The car read mostly in the 115-130 range, with a couple of exceptions....very high on the resprays (duh) and very low RIGHT at that deep scratch!:faint2: Nothing's ever easy. I would have thought that someone had tried to sand it before, but the edges of the scratch were elevated and rough, so I don't think that was the case. Just bad luck?

It wasn't much of an improvement, the flash just makes it appear like it was.

Polished with HD Uno. I chose Uno since time was a factor. Uno didn't dust at all, and I knew I could go straight to Poxy and skip an IPA wipe or post-polish wash. Win-win!

At this point, I had to take the camera away from Sebastian and put him to work! He got the hang of the polishing pretty quickly, and he really helped me get this car done on time.



After polishing, I had Sebastian apply Poxy to the paint while I cleaned up the exhaust tips.

Finally, we were ready for some after shots. We were going mostly for an increase in gloss and shine instead of correction, and unfortunately the camera couldn't capture the improvement very well. In person, the difference was very noticeable. Mostly though, I just love the shape of this car, so I took as many pics as I could!

Thanks for looking!
 
Looks good, Mike. There's not always a lot you can do with deep defects like that, hopefully the client was understanding.



"(I refuse to spell it "Polysh". That's just stupid. )"



It wouldn't be stupid if you were British :nana:
 
I agree the scratch is mostly hidden now. NIce work, and difficult given all metallic.



I looked hard at M Coupes before I got my Cayman S. I wish I could afford both!

Thanks Charlie! My friend understood. Having him watch while I took before, during, and after readings while sanding really made it clear (ha!) that there's a finite amount of paint on the car, and you can easily go too far.

Thanks Brad. I actually found an M Coupe before I sold my M3 that I'd thought about trading into, but it was an 07 with 101k miles, and rough ones at that. The thought of the S54 engine and transmission in a smaller, lighter package appealed to me, but the one I found was just too poor an example to trade for.



And your stable is awesome as it is, even without an M Coupe in it! :hail:

Nice job Mike. I totally dig this color & love using that UNO/MF/POXY combo as well.



Thanks David. I'm not usually a huge fan of "duller" colors like this, but it fits the car pretty well IMO. And I'm VERY happy with the ease of use of UNO/POXY together, it will probably become my go-to one-stepper!
 
Nice work and I'm sure the owner was happy to learn a thing or three about properly maintaining a car.

Great work Mike. I can see a nice gloss in the paint now.



Thanks Bryan! I wish it hadn't been overcast the whole day, but what can you do? :nixweiss

Beautiful finish Mike!



Thank you Thomas! BTW, I had an Uno-related question for you....do you prime or not when using Uno? I seem to remember someone saying not to prime, so I didn't. It seemed to work well even without priming.

Thanks June. My friend was pretty excited after all was said and done. He initially was questioning why it would take as long as I told him, but in the end, he was very happy with the result!
 
Looks quite glossy! Always nice to allow the flake in metallic to come out by making the clear-coat as clear as possible; I bet she looks at least as good as when she was first delivered to the first owner now!

Nice work Mike!

Looks great....i bet the wheels were a pain with all the spokes.



Thanks guys, I appreciate the kind words as always.
 
Were you using the cutting mf pad or the wax mf pad with UNO. It looks like the cutting- just want to confirm. I have a Volvo tomorrow and have the exact set up, but have not tried the UNO with the mf pads.



Thanks, Rob

Hi Rob, that was the cutting pad I was using. This paint was relatively hard, more so than most BMWs I've seen, so the correction was only maybe 60-70%. But it finished down very well, and under the Brinkmann and LEDs the increase in reflection and clarity was easy to see. FWIW, I know David Fermani and Junebug are big fans of Uno/MF together.

LOVE the Color and the car...Great job!



Thanks Greg, this car is right up there as one of my all-time favorites. I really don't care for the Z4 roadsters, but throw that sexy fixed roof and wide rear end on it and DAMN, it's a whole different car!:drool:
