When Menz SIP & Black Wool isn`t enough?

[noahabel]

As the title suggests, I seem to have hit a wall in correcting some of the deeper scratches in my 10 year old BMW paint. I recently went at it with SIP (PO 83) via black wool on a rotary at low speeds (1-2 on the Vector, so <2000rpm I`d guess) and at the time I was doing it, I thought I got 90% of the defects. I guess my lighting was inadequate because now that I`ve seen it in the sun, there are still plenty of defects remaining.



None of the scratches can be felt with a fingernail, but they are there. So where do I go from here? More aggressive compound (Menz PG or Optimum Hyper?) or increase pad speed (not my ideal choice)? Or, do I (eek) wet sand? Problem with sanding is that the defects seem to cover most of the horizontal panels (and maybe the vertical ones but I can`t see them in normal lighting) and I`d be loathe to wet sand entire panels. I also have no idea where my paint thickness lies at this point.



So, thoughts? TIA.

There`s not a lot left other than a heavier compound or wet sanding. You could go with Meguiars 105 or 3M Extra Cut Compound if you don`t want to sand.

Would those rate as less aggressive than PG or OHC?



BTW, nice avatar, Spike.

Sounds like a solution for Presta Ultra Cutting Creme. It`s cheap, locally available, has a short learning curve, and is best known as "rocks in a bottle".

PG isn`t all that aggressive, really. Lots of folks don`t have good luck with OHC either. Shrugs.

[noahabel]

Really? Well that`s disappointing.



Where, exactly can I find Presta locally?

Meguiars #105 /thread



Seriously. I can take spider swirls and holograms out of PPG CeramiClear using #105 cut slightly with Optimum Compound and a Meguiars 8006 yellow polishing pad.

[noahabel]

That`s a solid endorsement. Is that via PC or rotary, Scott?

I`ve seen you mention a few times about cutting 105 with OC. Would you recommend having a small bottle pre mixed or mix as needed? What ratio do you use to get good results? I tried searching your posts to find a ratio but, couldn`t. Thanks!

Rotary, 1000 rpms.



I cover it with pics in this thread: http://www.autopia.org/forum/click-brag/106702-325-regal-a6.html

[noahabel]

Now, why can`t #105 be easier to locate?



Scott, it looks like you cut the 105 with OC to extend the working time and reduce dust, yes? Would any other compound be adequate for this, maybe some old Menz IP?



EDIT: Since Meg`s seems to recommend using this with wool, would you recommend something like the green Edge 2K or purple foamed wool or should I stick with a light cutting foam (Edge blue)?

[gmblack3]

noahabel, I would try the yellow wool and 3M ECC, which you will need to follow with SIP/orange LC or new megs yellow diamond polishing pad. Then finish up with UF or 106.

If you want the real "rocks in a bottle" try Strada 1000. :nervous2:

Instead of mixing products, why not just buy 95? It has a cut of 12 (like 105), but has a longer working time.

I`m surprised you don`t need a waiver to buy that :).

I`ve used it with Meguiars yellow Solo wool pad and an American buffing white foamed wool pad-excellent results with both. Usually though, I can get by with an 8006 Meguiars yellow foam polishing pad, leaves minimal buffer trails too.
