Paint color coming off on pads

Black_Sunshine · 07-24-07, 03:22

Hey guys, I finally got to test out my new UDM this weekend and am full of confusion. I'm teaching myself on an old busted accord with basically destroyed paint. It's completely full of oxidation. I cleaned and clayed the hood then taped off half. Started with OC on a white pad... I know I should use a heavier pad but I have three white pads to destroy and only one orange (Lake country CCS 6.5"). Anyway the green paint came off on the pad so I guess it's a non-clearcoat, one-step paint job.

So does the remaining paint destroy the pad? I scrubbed the things like crazy after but 90% of the color stayed on the pad. Should I keep using them on clearcoat finishes, or will the green paint scratch or transfer to other surfaces from the pad?

Okay so I did OC white ccs pad on speed 3 then wiped off, then I used OP white separate ccs pad on speed 4 and this is where I ran into trouble. I couldn't seem to get the polish to break down. I swear I polished a 2x2' section for 30 minutes and the polish looked exactly the same. I gave up and wiped it off with MF. The oxidation was gone but there was very little gloss to the surface. Any ideas as to what is going on here?

No idea why it's not doing the correction (ss is usually sorta soft, but I guess this shows that you can't generalize too much).

I've never had any problems from ss paintstains on my pads. I've even used black-stained pads on white paint without problems but a) I'd really cleaned them well, regardless of the remaining stains, and b) it still might not've been a great idea

I'm not sure how the speeds on the UDM translate to the speeds on a PC , but on a PC I almost always use speed 6 to polish (correct). If the polish doesn't seem to be breaking down I'd bump up the speed.

If the OC didn't break down either then it could have left some marring that the OP couldn't take out.

Another possibility is the Accord has clear coat failure and you're basically trying to polish the base coat in several places. That would explain the color transfer on your pads and the lack of gloss.

I think you may have something on both of those suggestions. Though I am now 90% sure that car was repainted by a budget shop that would have probably used an acrylic single step paint. I read somewhere that the UDM will be faster than the PC at equal speed setting. That's why I used lower speeds, but maybe it was still too slow.

I have tomorrow morning off work so I'm going to go back and try again from scratch using higher speeds. I'll report back here on my results and I would take pictures but I need ten posts first.

Thanks for the help by the way!

Edit: Pic Attempt:

Lol it worked, check out that sexy beast, I taped my test section so that I don't hit the rust/bubbles, etc. This is the before anything pic, after pics tomorrow.

Wow--now that's what I call a practice car! I wouldn't worry about the pads turning colored, I'd worry about that paint ripping the pads apart!

I have had good luck with SS paint-stained pads getting clean by soaking in dishwasher detergent. Then for the final rinse, I shoot a mist of Simple Green, then rinse out, and the paint comes almost completely out.

I know its not recommended, but a little dish soap will get most of the pad clean, just be sure to rinsh and wring out all the soap. I also follow up with my wet/dry vac to remove any remaining water and surface contaminants left in the pads.
