When Menz SIP & Black Wool isn't enough?

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.

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.

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!



Sorry to hijack:wavey
 
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)?
 
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.

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".

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'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.

Because I already have 105 and OC. That's about $100 right there.

Sorry Scott. It was aimed at the people on this and the other threads that may not have both or either one. It would just be easier to buy the 95. Not to mention, you don't have to mix anything up. You obviously have a lot of experience with it and it works for you. Just giving another option for the others. I think 105 has stolen the spotlight. You hardly ever hear about 95. I like the 105 just the way it is, quick and effective, but for someone looking for a longer work time, 95 fits the bill.
 
For comparision



This was quoted from another site by Mike Phillips



M95 uses the same abrasive technology as M105 but as Jason Rose tells it, "it doesn't have all the bells and whistles that M105 offers", that is it doesn't finish out as well as M105. It's targeted at the body shop industry for people that want a fast cutting compound and are not as concerned about finish quality, it's more of a traditional, normal cutting compound.
 
So would M95 require an intermediate step before final polishing, where M105 may be ready for final polishing by itself? That's worth the extra dough right there. Though I'm mostly concerned about the horizontal panels and would be fine hitting it with 3 steps before LSP (ZAIO + CS in my case).



So my plan may be:

M95 w/green, yellow or foamed wool at low rotary RPMs

Menz PO 83 SIP w/yellow or white foam via UDM

Menz 106ff w/white or blue foam via UDM

ZAIO + CS



Or:

M105 w/yellow foam or foamed wool (cut with SIP?) at low rotary RPMs

Menz 106ff w/white foam via UDM

ZAIO + CS





If the M105 is that powerful, I should think I could get where I need to with a few passes and moderate cut pad, right? Green Edge wool too much?
 
Noahabel, your plan looks pretty good, but I'd change a couple things...Use the rotary for every step.



Use the purple foamed wool with the M95

Use the purple foamed wool with SIP

use the LC white foam with the 106FF



Or:



purple foamed wool with M105

white LC foam with 106ff



Remember that you were already planning on doing the most dangerous part (compoundiing) with a rotary anyway. Since you have the dangerous part down, use it for the other steps, too. You'll get much better results with a rotary than a UDM.



Keep in mind that M95 and M105 are *serious* compounds. Like, the Biggest of the Big Guns. You might want to go with an easier to use compound that doesn't cut as much, and use it multiple times rather than reach for a big gun. Menz Power Gloss is very gentle for a compound, and it's very easy to use. Many times, you can go straight from MPG with a purple foamed wool right to white LC foam and 106.



M105 has a serious learning curve, too.
