Ok, my experience with PC so far...

...so there I am... car washed and dried, pull out the clay bar and go at it.

so, clay bar is done...then I pull out the painters tape and get to work.

About 2.5 hours later, and my car looking like a crash test dummy, im ready to get to work on compounding. I pull out my PC and my Meguiars M105 ultra cut compound. Affix the backing plate to my PC and attatch the Lake Country Orange pad.

Grab my bottle of black baron pad lubricant, give the pad one quick mist. Grab my bottle of compound, shake it up a little and draw an X across the pad and then begin massaging the compound into the pad. Get done, pad looks like it could use a little more priming (some spots where it didnt look like any compound got to)...so I put a little more here and there and keep massaging.

Finally, pad is primed and ready to go. I place 5 pea sized dots of compound on the pad, up, down, left, right, and center. Place the cord of my PC over my shoulder and place the pad on the surface and begin to manually spread the compound around on the paint. Then, I set my PC to 2 and start slowly spreading the compound around for a few passes in each direction. I stop the machine, set the selector switch to 5 and turn it back on and begin making somewhat slow passes, left right, and up and down. Putting a little pressure on it, not so much that the machine "bogs down", but i have pressure (dunno how much, i guess I need to do the scale test).

Being my first time, im not really sure what to expect or what to look for, so I am careful not to move too slow, but not too fast. I know that once you start to not be able to see the translucency of the compound, it's time to stop. I know angelo told me to buff each section for about 4 to 5 minutes. Well, after about 2 minutes, I notice that it looks like the pad is starting to dry up...or at least that's what it looks like, cause when I make a pass in one direction, i can see compound trail, but a pass in the other direction looks like it's dry. So I stop, mist the area with my final inspection and start to wipe away the residue. For some reason, wiping up the residue with the final inspection and a microfiber towel leaves streaks...so once im done with that, i grab a clean dry microfiber and wipe away the streaks. Surface looks good...but have I done anything??

Hmm...no haze...and come to think of it, im not getting any debris on my pad (was told that as you abrade the surface of the car, what comes off the car will start to mix with the compound and start clumping). Well, I never seen anything on the pad, no clumping or nothing. In fact, the pad looks pretty clean, except the white haze of compound.

I did the whole hood with one pad...and was told that it would probably take me 2 pads just to do the hood. So...this leads me to believe that I am not doing something right. Not enough pressure, too much compound, not enough buffing time? Like I said, the reason I stopped where I did is because I thought the pad was starting to dry up and didnt want to dry buff.

I was out in the garage buffing at night...was about 80ish degrees. Flourescent light above me. Cant really tell if the swirls are still there...ill have to take a look in the morning in the sun light.

Anyone have any ideas what I might be doing wrong?
 
I would think that the amount of debris that comes off of the paint is relevant to the condition of the paint. I know that when I did my wifes car, the pad got gunked up pretty quickly. Until the day I polished it, the paint had never seen polish before.

How old/new is your car? Did you wash and wax it often before trying to buff it? Was the paint neglected and in poor condition?

Before inspecting your paint in the sunlight, I would suggest to you that you do either a straight IPA wipedown or a 50/50 wipedown to make sure that there aren't any leftover oils on the paint, masking any imperfections.

I'm by no means a pro. I was just recently bitten by the detailing bug and can't stop. My wife likes to call my hobby an obesession. I guess I would have to agree. :D
 
my car is an 07 and the paint is in almost new condition (with the exceptions of a few rock chips and minor scratches). and the paint is well taken care of. i wash it often and have waxed it several times. already did 1 clay bar session, used pre wax cleaner, glaze and then mothers liquid carnuba wax. then today i washed/dried and clay barred it again. then started to polish.

Also, for some reason, clay barring isnt doing anything for me. I mean, i can put my hand in a sandwhich bag and rub the surface..and there are bumps..almost feels gritty. so i do a clay bar on the whole car, and i never feel any "grab" or anything, it always feels slick right from the moment i start rubbing the clay on the surface. I spray a light to moderate amount of lubricant and start rubbing, then wipe off with mf towel. put my hand back in the bag and it feels better but can still feel some bumpiness or "grit".

dunno..i just dont want to ruin my paint by dry buffing...which is why i stop when it starts to look a little dry. maybe I should go longer?
 
Sam , so far your doing ok for now. Just keep at it till you get the hang of it and if your passes are done in 2-3 mins that's fine by me. You can drop me a line when you have the time.
 
Your steps and procedure are fine. I use my PC with those exact steps weekly and I never have had any "clumping" on the pads.

It takes some pressure on the PC to see results. On the first couple of passes I will see the trail left by the PC/Compound and then as I pass over that same area a few more times, the compound dissappears back into the pad, usually leaving a fairly clean surface. There will be a minimal amount of dust, sometimes barely visible.

If you want to see the comparison between what you've just done and the untouched area, just run a line of painter's tape down the hood and polish right up next to it.:smile:
 
okie, ill just keep plugging away at it then. did the hood and one fender last night, going to tackle the rest of it today.
 
Luster, so when you see the compound disappear back into the pad, that is when you stop? also..is that what you call "flashing"?

The short answer is yes. When I start to see the shine show through. That's when I'll stop, spray a little QD on the paint and wipe with a microfiber.

You can shine a halogen work light on your work (or move it into direct sunlight) to see if you've taken out any of the swirls.

It takes a while with the PC, and as I stated before, it takes some pressure, not just the weight of the machine.
