I just ordered a gallon of Opti-bond, never used it before, but from the pics it looks like it might look good on plastic parts in the engine, especially hoses. Anyone ever tried this, and how did it look?
Yes, I'd definitely get a Flex over the PC if those were the only two choices. The thing that I find strange is that from what I've read people get better results with the PC than the Flex with the KBM, that just doesn't make sense to me.
My problem with the PC is the vibrations kill my arms after a while and to get similar results you have to use non diminishing abrasives with a LOT of pressure. That reduces the spectrum of products that can be effective and it's just more difficult to use.
I did not get that impression, especially not on cars with hard clear coats. If the defects are easier to remove then I could see that but I still think the rotary is a few steps above even a flex. However a flex is much better IMO than a PC.
If you are getting rust spots that means you have a hole through the clear coat, the base, and the primer all the way to the metal, I doubt that's what those specks are though.
No work time was a lot less than Power Gloss. PG removed 2000 grit sanding marks in one pass, 105 still left some marks after 3 passes. IP removed the marks after 3 passes.
