i read the description of Men. 85RD on AG before i bought the product and the bottle also says it does not contain any silicones and fillers...
Just keep in mind that the Menzerna line is what is categorized as a "Professional Line", just like 3M makes a Professional Line and Meguiar's makes a Professional Line. These products are formulated and targeted for use in the refinishing industry which is what you and I think of as "body shops". That is where fresh paint is sprayed then often sanded and buffed and for this type of "fresh paint environment" you only take and use body shop safe products, thus the no-silicone feature of the product.
If you're a consumer, working on cured paint, which is 99.9% of us, me included unless I'm working on a brand new paint job, the silicone ingredient is a non-issue.
SO, after i 'final polish' with 85RD, should i do a 11% IPA wipe down before my LSP, which in this case is either going to be DG 105/601 OR Optimum Opti-Seal.
There's two schools of thought on this topic.
1. You must chemically strip the paint in order for the protection ingredients to properly bond
2. Go ahead and apply your LSP without chemically stripping.
Keep in mind you risk marring the paint when you chemically strip. If you use the
SF 4500 – Super Finish Polish (PO85RD) and you're working on black paint you're going to leave a mirror finish behind. Wiping with IPA will tend to dull these results down, not make the paint look even better.
Follow the manufactures directions for the LSP, if they say you need a chemically stripped finish then chemically strip. If they don't then personal preference.
I have articles on all of the above topics...
