M105 on 5.5" orange not enough, next step?

I recently detailed my car, did a few passes with my PC7424xp of M105 on a CCS 5.5" orange pad and in some places had some (but not great) improvement. I'm curious whether I should step up to a more aggressive 5.5" pad or just go with both a smaller and more aggressive pad. any suggestions?



also I have a 4" backing plate, would it be a bad idea to use a 4" pad on a 4" backing plate?
 
A more agressive pad may be the answer.



You dont want the outer edge of the pad to be the same diameter of the backing plate. Bad stuff can happen if the backing plate touches the paint going at 3000 rpm. :doh
 
what kind of car? Color?



you can use a same size pad/backing plate just ONLY use it on flat surfaces and not into corners or over hood louvers.



Try a purple foam wool pad or a surbuff pad.

If M105 isn't cutting it (no pun intended) your choices are more aggressive pad or compound. M105 and Power Gloss are about the most aggressive thing in my cabinet since I disposed of all the rocks-in-a-bottle compounds long ago.



I have also disposed of my yellow LC pads, PFW has worked as well for me without the marring. I usually only turn to Surbuffs on something I'm thinking may need wetsanding. Most times the Surbuffs have saved me from sanding but I ended up working to remove the Surbuff's marring and haze.



As mentioned, you want some overhang on any backing plate for a safety margin. All my 4" BPs are actually 3.75 or thereabouts, perfect for 4" pads. Although you will get better cut and correction with smaller pads I reserve them for spot correction or working in confined spaces. Thinking using a 4" pad on wide open spaces for more correction isn't wrong, it's just more work IMO and more difficult to keep a smaller pad flat against the paint, especially if there's a bit of a reach involved. Try a more aggressive pad.

thanks for the help guys, I did some research on them and ordered some surbuf pads last night so we'll see how that works out. I hear light pressure is best? and since this is a pretty aggressive pad should I be worried around edges about burning?
 
creeper- IME (which I'll admit is limited) the SurBuf pads aren't "dangerous-aggressive" so I don't think you'll have to worry about that. You don't want to apply so much pressure that you bend the "fingers" of the pad too much, so you shouldn't have any problems with grinding the edges of the pad into anything.



Your options have pretty well all been mentioned:



-3.75" plate with aggressive 4" pad

-SurBuf pad (I'd stick with something smaller than 6")

-Meguiar's MF cutting pad (ditto on the size).



When you say you did "a few passes" I can't help but think how serious correction via DA/RO can take hours per panel; even with the products now on the market, doing rotary-level correction via PC can take a while.



I'm tempted to suggest that a gentle wetsanding (say...3K or even 4K) might be a viable option, maybe even as safe (or *safer*?!? :think: ) than trying to push the PCXP to the limit of its abilities. Just thinking out loud....
 
I'll see how this pad does, I wasn't at full speed so that may have had something to do with it but I'll play around some more on my old hood



btw it's a pontiac trans am (navy blue metallic)

SEX ON WHEELS!!!! my first ws6 was NBM and man did I love the way the paint glistened on that car! I've done a few birds/GM's and i'm tellling you the purple foam wool w/105 followed by a tangerine hydrotech with 205 is your combo. The surbuf should do the same though. Post some before/afters, i love that color on birds!

I always keep a fresh coat of wax on it to hide the imperfections (118k miles on it..there's quite a few) and as you can see I've been through quite a few sets of wheels (I've owned 7 sets so far..) anddd I have a damaged ram air hood that I'm working on, really just needs finishing work and paint now
