New M105 is kicking but w/ KB method

[SuperBee364]

for pc`s does it matter if you use a 4" or larger pad? other polishes work better with the smaller pad and a pc (because the pads turn faster to build heat to work down polish granules) vs 105/205 which don`t need heat since it doesn`t break down...

Not as much as with other polishes. You will get better cut using 105 with smaller pads, but I used it successfully with 6" pads on the PC. I took out 2500 grit wetsanding marks in two applications with six inchers on the PC.

This gives me great hope for using M105 again on a PC. I tried quite a few hours cutting 105 with OC and OP to get longer working time and better removal but it seems like it either did nothing by turning to dust quickly and removing no scratches or creating a bad haze that I would have to go over again just to remove.



Subscribing!

I, OTOH, was unable to remove fairly light marring on the Yukon using PC/M105/Meg`s 8006. A harsher pad probably woulda worked a lot better, but that M105/8006 combo seemed just right for the job. When I tried to apply more pressure to the PC to add a little oomph, it did its usual "jiggling under pressure" thing (which would *not* have happened with a 4" pad).



When I put that same 8006 on the Flex, the marring (and even some nearby RIDS) came out quite easily.



4" pads *do* work great on the PC with M105 IME...but my jury is still out on the larger ones :think:

Todays fun involves a Porsche turbo in Basalt Black Metallic.



Before:







After new M105/orange via KBM with a PC and 3x straight IPA wipedowns. No M205 yet.

gmblack3a- Nice job correcting that Porsche. Two questions:



-How hard was its clear (I hear Porsches are all over the map these days; mine were kinda hard)?



-Which size orange pad were you using?

Thanks Accumulator.



Being a metallic I`d say its harder then a flat black porsche which is very soft. So if a flat black porsche is a 1 and a vette/audi a 10, I would rate this a 3-4. YMMV...



6.5" ABC pad with the scalloped edges. (no longer for sale )



I am still amazed the finish that the KBM will leave after removing defects like this. A quick going over with M205/PC/Black pad is all that this will need.

I am happy with 105/orange KBM, but I seem to destroy pads fast. The heat on the backing/foam are cut, delam, and spit foam dust. I`ve been playing with the pressure, but I don`t get the same results when I back off, but the pads last much longer.



Any experience other ideas?



Cheers,

gmblack3a- Thanks for the added info. I`m always interested when people get good results with 6-6.5" pads on the PC.



Cool that the M105 still finished out so well on that paint too.

Greg, This process is tough on pads, have you tried a different pad that might be more durable?



As I mentioned above so far I like the ABC scalloped edge best, but they are out of production. I think the key to those is the velco went all the way to the edge of the pad. I had been using these pads way back when (maybe 3 years ago when Patrick at excel sold them.) They always held up the best for me.

[AudiOn19s]

On the topic of destroying pads due to the increased pressure...I too had this issue. I ordered several 5.5` orange pads and use them with a 6" backing plate and this solved my issues with pads coming apart. KBM is still harder on pads than normal polishing but they don`t come apart like the others did. Obviously you have to use extreme caution when using a pad that`s slightly smaller than the backing plate so use at your own risk.

It still crazy to see those results with a PC and 6.5" pad. I use 4" pads all the time with a PC bc when I tried ther larger pads I would not get the results.

[Greg Nichols]

I have tried the method with 5.5 orange flat pad by LC, yellow and burgandy 2.0 by Megs, all of which are destroyed in short order. I like the KBM best with purple foamed wool/105 and my rotary, now that is a killer method. One must however follow up the hazing with a secondary polishing.



The pad makers need to redesign for the pressure issue, wonder if a dual foam combo, one to polish and an inner to handle the heat/pressure.

Greg, How many pads are you using per car and how many cars are they lasting for?



I have 5 of the ABC`s that I rotate thru on a detail. I have done 4-5 cars with them and they are still holding up well.

[Polished&Waxed]

what about the 3m soft pads for fill to separate the bp from pad?



I have been using 3m RC Perfect IT 2 5974? w/ LC orange KBM pc/6 super heavy pressure and just killing defects. This is at work so I dont have halogens but it will clean up if stepped down I just dont know how bad the swirling/hazing is on its own.



I really like how it slowly rounds the edges of deeper rids.
