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:
then when it arrived. Bret headed home and I will take it from here. Thanks for all your help man!!!
