Is this normal?

When using an orange LC pad with 3m PI2 RC if i put the pad to my ear after a go with it, it is sizzling, making popping noises. The paint surface is warm, and so is the pad.



I have not found a way to used this RC with the PC on 6 without misting the pad with water or QD almost everytime i do a section. It just dries out too fast. Or is it supposed to dry out in say...um, 45 seconds? 2x2 areas?



I did a search, and it is best to work this until it dusts, but i am having trouble just getting it to dust the way i think it should be dusting. Usually to make it dust, i am almost just burning off dried stuck on product. I dont think that is polishing.



Anyways, i just need a lowdown on how to use this stuff the right way.



The amount i use on the pad is a circle 1 inch in from the outside of the pad.
 
I haven't used PI-II RC for quite a while and I never used it with an orange pad, but no, I don't recall hearing it do that and I didn't have any problems with it drying out too fast :nixweiss I assume you're moving the machine slowly across the 2x2 area.



I don't think I've ever told anybody to use *more* product, but maybe that's what you need to do. I put mine on the pad in an "X" patter, rather than a circle but I don't see that it oughta matter much once the pad is primed with product.



I hesistate to tell you to slow the machine down as I do all my PC polishing at 6.



Sorry I can't be of more help with this, I just didn't encounter those problems. Things do get a little warm, but you're having a lot more trouble with it than I ever did.



Oh, and I would't use PI-II until it dusts, it breaks down before that. And you definitely don't want to *breath* PI-II dust, it's carcinogenic. So wear the proper respirator when you use the stuff (or just get PI-III instead, for a number of reasons besides just being safer to use).
 
Thanks for the feedback. It seems to work alot better if the pc is on 4, 5 is iffy, and 6 just smokes it.



Its easier to use with a white pad for some reason.



If i use somewhere like a 3/4 circle of the product and keep the pc on 3 or 4, it wipes off easy, and i can work it longer. With the pc on 6, i either have to scrub it off(i refuse to do this), or go over it again with more product, a QD works somewhat too.



If i mist the pad it doesnt dry out, but it is a pain in the arse to remove.



I think it is just one of those products that has a fine line of usability, and im too new at this to be able to figure it out.



I have tried it bearing down on the pc, and just letting it glide over the surface too. Not sure if it made a difference on speed 6.



So i guess i have a few options.



Get some SSR 2.5 :)



Use a slower PC speed



Or try alot more product and see what happens on 6

Is the PI-III RC non-carcinogenic? Or is this a problem with all polishes?
 
I wouldn't want to inhale too much dust from *any* polish, but the PI-II stuff is so dangerous it has to have a warning label. No such label on most similar products.
 
No, lol, i just type it that way because i never know if it will be considered a "bad word" if i type in ***.



Thanks anyways guys. I bought this stuff because my local paint supplier didnt have the PI 3 stuff, and the PI2 sucks, and it causes cancer, so i am trashing the bottle.



So... SSR 2.5 is pretty much everyones fav. right? I would buy DACP, but i have had it up to here - with stuff that doesnt remove well.

Wow! I am having a headache now! I bought a bottle of it from CarQuest because I couldn't find the 05933 & 05937 combo that you recommended locally. Good thing I was able to find some #80 & #83 to take care of what I needed to do. I do wear safety goggles and ear plugs when I use the PC, but now I need to bring out the mask too. Hope CarQuest would let me return it. I've been "away" from Autopia for a little bit around a year and seems like I have missed a lot of good info already. BTW, I believe the acronym (new to me) "LSP" means sealant like Zaino or BF, but I still cannot make out what those 3 letters stand for?

Layer Sealant/Surface Protectant? Little Something Pretty? Low Subject Priority?

Please pardon the off-topic replies. Better plan out the next detail this weekend. Stop wasting other people's time.
 
Heres an update:



I decided to give it one more try. I just couldnt believe 3m would put out a product that would give me such a hard time. I knew there was a "way" but i didnt discover it yet.



What i did was really no different than before. I put a circle of compound on the orange pad, spread it with the pc off, and started spreading it on 3.



Once the coverage was even i bumped it up to 4 for perhaps 1 1/2 min., then 5 for 1 min. No problems. Did this for 3 minutes or so and buffed off.



So i repeated and worked it on 4 for maybe 45 seconds, then 5 for a minute, then tried 6. It lasted maybe 30-45 seconds before starting to dust, so then i backed the speed back down to 4 and it was able to be worked for another couple minutes.



On 4 i was able to get it to a translucent stage, so i stopped and buffed it off with no problems.



I did this without bearing down on the pc much at all. So i tried it again with more pressure, im guessing maybe 10 pounds. It started to fling clumps out of the pad, on a speed of 4.



So my not so professional opinion is that it doesnt like speed 6, not for long anyways, and it doesnt like pressure applied to the pad.



It did a great job of removing alot of scratches on my 3 year old- wash it anyway you can to get it clean -daily driver.



There are just a few scattered random deeper scratches left after working it a couple times.



The finish seemed really clear and glossy, and i followed up with hi temps light cut, and this made it a tad more glossy.



This wasnt a whole car, just a door a fender and a trunk.
 
Thanks White95Max for the LSP explanation.

Glad it worked out (or at least beginning to) for you, JBM. I generally work on an area no larger than 2'x3', and so I don't think I put the PC for more than 50-60 seconds per section, but then I wasn't exactly looking at a stop watch to time myself. Let me try to slow down to see if it works better. I didn't use the 3M PI-II that I bought and so I am guessing it may require more speed to break down the product. Anyway, most importantly is to watch how the product works into the paint and not getting fixated on a speed or timing. I've read many threads on how other folks can finish their cars inside out for a couple of hours. Somehow it always takes me 3 to 4 just from wash to LSP, and that's just the outside, for a mini-SUV. Thanks for starting this thread as I've learned something more about the 3M line (been using 3M SMR (light) for a couple of years) for surface prep.
 
I worked the product as long as i did because i wanted to see how long it would take to dust on different speeds.



The product is translucent and wipes off easily long before it dusts on speed 4.



If i jump right to speed 6 though, it clumps, dries out, dusts, doesnt wipe off easily at all. Plus it will leave a ring of crap on the outside edge of my pad.



I generally think longer than 60 seconds is needed. If you are moving the PC at say 1 inch per second and it is 24 inches across, that would be 24 seconds just to do one pass. The pad has a coverage of 6 inches, and if you overlap by half, you have a coverage of 3 inches. That would require 8 rows of passes to get a 2x2 area.



If my calculations are correct it would take 3.2 minutes to do a 2x2 area one time.



I know this is alittle off, i think i move the PC at twice that speed, so lets call it an even 1 1/2 minutes for a 2x2 area :)



Edit: Now that i am thinking about it, i probably more the pc faster than that. Maybe 3 or 4 inches per second. So 45 seconds per 2x2 area after spreading it i guess. *Shrug*
 
JBM, I've had lots of trouble with 3M not breaking down. It just seems to cake and harden on the surface, requiring a spritz of QD to remove it. Based on your experience I'll try slower speed and less pressure.



Some polishes contain silica which are considered carcenogenic. Sound like PI-II contains it. The *safe* polishes contain aluminium (correct spelling :p) oxide as the abrasive.



BTW, everyone knows that *arse* is also the correct spelling. A.a.s. is a type of donkey. :lol
