1987 Porsche 928 S4 w/ 93k miles.

First I want to say thanks to Bret, he made the drive down to help out for a few days. Then he took over with the polishing. I am sure that had nothing to do with the fact that I just got a new Metabo the day before. I could not pry that rotary out of his hands.

A few before pics from when I went to look at the car:









The owner was kind enough to drop off the car on Thursday before I went to work. So I vac'd the seats and applied some Leatherique RO to the seats and let the car sit out in the hot sun while I was at work.



Some before shots:















Wheel wells, wheels and tires got 777 APC 1:4 and scrubbed.
Wheels where in good shape, just one of the fronts had some crub rash. Otherwise there where pretty clean. Inner barrels where pretty dirty (brake dust.) I tired some of the REAL WHEEL CLEANER by PPC and it would not cut the old dust. I used PB SnR and that cut it without issue. I used both products as a spray and rinse.

Then we did a wash with Duragloss 901, sheepskin mits and 2 bucket method.

Pulled the car inside and clayed. I used blue magic clay and Bret used the sonus green clay, both used body shine #20 as a lube. We where suprised to see a lack of bonded contaminants. The car has been sitting outside for a while as the owner was building a garage.



Then it was time to start polishing and the testing of products began.

Here is Bret trying out my new metabo using the edge system and a green wool pad w/ presta 1500 polish. I am telling you that this setup is so smooth, it makes using a rotary almost effortless.





The defects just laughed at us. So it was time to step it up to:

black wool P1500
green wool P1500
green foam PSMR

Not sure how much we are going to cut to get those deep scratches out.

Darn bulb blew on one side.



Decided to do some wetsanding:





Heck lets go for another round:











Give us 80 total man hours to have the car looking like that.

Bret continued to polish while I worked on the interior. Most of the carpet in the porsche comes out in sections. So I removed the sections that I could, laid them out on the garage floor and used our kirby on them. The wife just loves when I used "her stuff" on details.

By this time a camry had arrived that I booked a few days before. So I gave the inside of the camry a good vac while Bret happily buff away on the porsche. I fired up the mytee extractor and used it on the carpets of the porsche and also used it on the camry interior (seats and carpets.)

Bret was about halfway done polishing, so we called it a day. We setup the airmoves and a fan to dry the inside of the camry. A few hours later it was 90% dry.

Got up the next day and decided to knock out the camry first with a one step polish, ect. We let it sit outside all nice and clean only to be rained on a few hours later while we worked on the porsche.

Bret wanted to try out the Menzerna SIP with the black wool. He had been using the presta 1500 but wanted more cut. He liked working with the SIP, but as its rated at a 2000 cut. It was not enough for this trashed paint.

Like Ryan said use very little of the SIP, here is Bret posing with the amount that he used on a wool pad:



So I remembered that I had a bottle of vintage (1993) Presta 1000 cut polish that a friend had given me a few weeks ago. I shook it up for 15-20 mins. Bret gave it a try and was happy that it even had a longer working time then the presta 1500.

Before anything:



After presta 1000, black wool at 1500



After 2 passes of ZPC white LC pad PC6:



Looks like we finally found a winning combo. We finsihed the rest of the car with this combo. Bret still happily running the metabo and I was using the PC.

We then took the car back outside for a Z7 wash to get all of the dust/splatter off of the car. Mind you that the presta line does not dust that much at all.

After the wash:



After the wash Bret and I did an application of ZAIO applied with white LC pads PC6. That pretty much wrapped up Sat, another long day. The 928 was just looking a "little better" then when it arrived. Bret headed home and I will take it from here. Thanks for all your help man!!!

Sunday morning I did 1x of Z5pro and an application of Z8 a few hours later. Also applied CS to the rear wing. Time was running short and I still had to quick vac the carpets and get them all installed in the correct position. I also vac'd the rear hatch area. Cleaned all the glass and did the 2nd step of the leatherique process by cleaning the seats w/ pristine clean. This is some high quality leather for sure. Nice and thick. I gave the interior dash a quick wipedown with the same towel that I used to remove the prestine clean. I then applied a quick coat of Z-16 to the tires. I think I missed it, but Bret had applied ZAIO to the wheels on sat.

Area that was wetsanded, man I wish the whole car looked this clear.

wow - what a fantastic post ! I love the wetsanding photos before / after, and during the process. Great to demonstrate the incredible number of hours that can pass doing paint correction like this.

Great work - and thanks for taking all the extreme effort to make this landmark post

Man ..did the owner even recognize his car when you returned it ? Great job..

It's hard to believe it's the same car!
Unbelievable work.

Thanks, Bryan, for inviting me over to help with the 928 and Camry. It was a lot of fun doing all that polishing with your new Metabo and the wool pads. I still can't believe we had to use a wool cutting pad and a compound used for removing 1000 grit sanding marks to get the paint looking good.

I promise I won't hog your new Metabo polisher again. Gotta start saving my nickels for one of my own. The lighter weight alone makes it worth the money. The combo of Metabo plus The Edge wool pad system made polishing about as easy as it gets.

Wetsanding is fun to do, as long as you're confident you can remove the scratches. We were using Presta 1500 compound and they came out with just a few passes of the rotary. If the money was there it would have been nice to sand the entire car and buff it back.

Can't wait for the next one!

Bry, you and Bret did a great job on the black Porsche, nice work guys.

capevettes

Nice job That was quite a transformation. Very labor intensive but the final results were worth the effort. Interior looks much better too. You guys are good

Thanks everyone for your kind words.

Bret, Thanks for all your help and showing me how to wetsand. Its really nice when you have proper guidance and tools to get the job done.

For anyone thinking about a rotary, I can highly recommend the Metabo PE12-175. Its not cheap at $245 shipped from allprotools.com, but its very lightweight and balanced. I had been using a hitachi to this point that will be collecting alot of dust as a spare.

Awesome work.

Now don't forget to tell the owner to stop washing the car with a brillo pad.

The 928 turned out awesome.
You fellas did a GREAT job.

Congrats on a huge turn-around.

Thanks Jim! Wish you could of made it over for a wetsanding lesson. When are we gonna detail the 300? I want to see you get with some green wool.

chevyvette1

AWSOME job, looks like a different car, what kills me is how people can let there cars get to that point in the first place I dont even like to drive mine and let people see it even it's just a little dirty my friend makes it point to see if he can find a dirty spot

GREAT JOB!!!

Stickman81

I was hoping we could knock out the 300 in the next Misfits get together.

Thanks CV1!

Jim, we need to give it full bling! Lets try in June.

All those steps are too much work for me. I saw a commerical for Nu-Finish, it seems to do all that in one step and lasts for 52 washes!!!

Awesome Job!!! Since guys here seem to know so much, can someone take a look at my thread and see what's happening here - http://forums.corvetteforum.com/show....php?t=1705061

I'll appreciate your input and help.

Thanks...
