Little experiment with the PC vs. spider webs

If you are not comfortable with a high speed give this a try.



1. Wash & Clay



2. Foam Cutting Pad and Parko 1750 compound(speed@5), slow passes. I did try 6 but to much vibration for me.



3. Foam Polishing Pad and Meguiars Diamond Cut 2.0(speed@5)



4. Foam Polishing Pad and Meguiars Speed Glaze(speed@5)



5. Foam Finishing Pad and Meguiars #26(speed@3.5)



6. Removed #26 with Micro bonnet for PC(speed@4) and micro towel by hand for steps 2,3,4.



This takes some time but, good for the new detailing guy with limited risk instead of a high speed mess-up. (Remember the PC will burn at higher speeds if you just let it sit in one spot to long)



The 1750 removed the "webs" and lightened a couple of scratches so, I will be using Parko 1500 on the other side of my truck to look for and difference.



If anyone has other combinations with the PC for the job of removing "webs" please reply with post.

Good job, but 5 is considered high speed and diamond cut is typically not for the faint of heart. I would think something less abrasive such as DACP should be sufficient for swirl marks.
 
DACP or Swirl Remover 2.0 would be perfect for swirls but not for webs or scratches. I have not been impressed with the Diamond Cut 2.0 and have moved to a more aggressive compound such as the Parko line. In my opinion you could eliminate step 3 and move to step 4 if you wanted. I believe that a setting of 5 on the PC is compatible to a setting of 3 on a Makita 9227 high speed buffer. JMHO



Thanks for the feedback Greg

Be careful about comparing speeds of the PC to speeds of the Rotary...



I use an infrared thermometer to monitor heat rise as I go... There is NO comparison between the rotary and PC...



By definition, they are different.

Both have their place, but they are different.

Choose the right tool for the job.

Jim,



Do have the temps with a pass of the PC at 5 vs. the Makita at 3?



Would like to know.



Thanks

I forgot to add my rule of thumb for heat.





Do not exceed 115 degrees. If you do, you can expect damage with PC or Makita.
 
Dave, i don't use the Makita... so I don't what RPM #3 is...



I usually run my PC at 5, and surface temp is just above room temp... 75/80 degrees.

Running my rotary at about 1750 RPM (with wool cutting pad and minimal pressure), the temp goes to 100 ight away. 120 is not uncommon when 'addressing' a problem area.



The temp sensor is only $50 at Radio Shack.

I've got a Makita Rotary. That depends a LOT on how fast you use the machine. My orbital I can turn on full speed and hold on one spot for awhile and the paint temp hardly rises. If I stop for just a couple seconds with the Makita even at spd 3 the paint will get hot.
 
Since I have a PC, the Makita 9227C and the Dewalt DW849, I can tell you very definately that the PC at 5 or 6 is no where even close to the rotaries at #3 or even 2 for that matter. The rotary is a VERY different animal to that of a PC. :) Moreover, Diamond Cut is designed for the rotary not the PC. As such, it would be difficult to judge a product without using it the way it was intended; with a rotary.



I have had excellent success with Diamond Cut. Moreover, if you can not get a mark out with Diamond Cut, a rotary, and a wool pad, it is wet sanding time. Truthfully, rarely do I have to go to this extreme. At least 90% of the time, a cutting foam pad and DACP with a rotary will do the job, and very well.



Just IMHO!:)
 
Nowhere do I say that the PC is a rotary. Please read the original post. I'am simply saying that the same results can be achieved with the PC as with the rotary with practice and the right product.



By the way, I have had suscess in removing deeper scratches with the PC. Its all in the product you use. Read the post again.





It does'nt mater what machine you use if you can get the same results.



This was just a experiment with the PC.

You imply that the PC and the Rotary are "compatible" at the settings you state. Hence your suggestions presents an opinion that one could be replaced with the other under those circumstances. I believe that is simply incorrect. I have used a rotary for over 12 years and the PC since the day it came on the market. Does that make me an expert? NO, but it does imply that I may have an opinion that is based on experience from using both products.



No one is questioning your writing ability or faulty parallelism so therefore, please do not question my reading ability.
 
Doesn't a rotary still produce an awful amount of heat even at say 1000 RPM? I find it's difficult to get the PC to heat the paint appreciably. :confused:
