Great work! I have been following your detailing for several months and have started using your techniques and product selections on my own cars (I'm just a home detailer). I've got a 1991 Red E30, a 1993 Black E36, a 2005 Khaki X5 and last but by far my favorite.... a 1977 Black Pontiac Trans-Am.
I noticed on this detail you didn't use the Pinnacle Advance Finishing Polish. Any reason why? I just did my Red E30. I did the M105, The PAFP, then the SF4500 just like you use. I use a Griot's DA. It turned out beautiful and I was extremely happy with the final results. However I really had a hard time seeing any difference between the PAFP and the SF4500 step.
Thanks so much for your time!
I actually have stopped using the Pinnacle Advanced finishing polish on a lot of my multi step corrections. The reason is simply that I am able to achieve a good enough finish after the compounding step, that I simply don't need to use the Pinnacle. The SF4500 is a milder abrasive, and yields a higher gloss so that has been my go to product.
If I had a situation where my compounding step left a lot of haze or defects, then I would go for an in between step like the Pinnacle, or Menzerna's SF4000 before the SF4500.
To answer your question/comment regarding not seeing more gloss from the SF4500, this makes sense. Your paint is single stage, which means it's base coat (color coat) pigmented with clear. The SF4500 is primarily designed to burnish clear coats to the highest possible gloss. The look of single stage paint is different than that of a more modern base/clear coat paint. Also, your single stage paint responds very well to the oils in the Pinnacle polish, and at that point, additional polishing steps are not needed IMO. You might opt for a coat of two of Meguiar's #7 show car glaze, it is EXCELLENT on single stage paints. You can then top that with a wax of your choice.
Be VERY careful of edges if you're using a PFW pad, and 105. That combo is very abrasive on your already thinning single stage paint, and it will easily burn through edges. It's a good idea to tape off all edges and high spots in the paint for the compounding stage, and use only your finishing polish over these surfaces.
Hope that helped!
