Help! I made a bit of a mess with a Bigfoot
Hello,
I'd be very grateful for any advice please - I'm a novice and wanted to polish out some minor scratches from my wife's car.
I used Uno Protect and a yellow wool pad and when I finished, it looked stunning! but now - a few weeks later - I can see pad marks!!!
Could someone help me understand:
1. What I did wrong
2. How I could have told I was doing it at the time given it looked first-class when I just did it
3. How to avoid doing it again
4. How to get rid of the marks now
THANK YOU VERY MUCH INDEED!

To put it simply, I would’ve used a less aggressive pad and made more passes… Wool is pretty nuclear, I only use it when I’m trying to clear up wet sanding.

wool pad is very aggressive, definitely need to follow up with a foam pad. You might not have noticed the issues at first due to fillers in Uno Protect, once that wore off you see the true condition.
Polish again with a foam pad, either yellow foam or white if your paint is soft, then it will look much better. Make sure to use plenty of pads, many beginners think it's possible to do a whole car with 1 pad.

What did you use as a polisher?
Regardless - see what I wrote here,
Fibers are a form of abrasive - Foam Pads vs Microfiber Pads by Mike Phillips
The way to fix it is to re-do the entire car only this time use a foam polishing pad with the UNO Protect and an orbital polisher.
I would start by doing a Test Spot to make sure your choice of pad, tool and product removed the defects BEFORE buffing out the entire car.
If you used a rotary polisher then these would be called holograms. If you used an orbital then this is called micro-marring and the pattern is called shadow-effect.

Re: Help! I made a bit of a mess with a Bigfoot
Hello Mike,
Thank you very much everyone for your help.
I used the Bigfoot RO and to be honest, I chose the yellow wool based on a Rupes YouTube video that recommended it could be used as a single stage quick detail (Express Enhancement - [RUPES Replies Season 02 Episode 08] - YouTube)…
I did even do a test spot but the problem was the Uni Protect completely hid the marring :/
I’ll go over it with the white foam pad then? Any tips on how much pressure to apply would be great too!
thanks!

Thank you very much everyone and thanks Mike for your thorough reply!
I used a Bigfoot 15 RO but I followed the quick detail Rupes advise here: Express Enhancement - [RUPES Replies Season 02 Episode 08] - YouTube
I guess wool pads were too aggressive but there was no way I could see the marring despite doing a test spot because the Uno Protect hid the marks!
Do you reckon a white foam pad then? Any suggestion for how much pressure please?
Thank you again!

The RUPES white foam pad is a soft finishing pad - together with the RUPES UNO Protect it "might" remove the micro-marring.
If it were me? I'd use the yellow RUPES pad and together with the RUPES UNO Protect that should get it.

With any brand of long stroke, free-spinning random orbital polisher the general rule-of-thumb is just light pressure. Basically a little more downward pressure than the weight of the tool. This can be a tick tricky when buffing out vertical panels because at the same time you're pressing the tool against the panel you're also holding the tool up against gravity and moving it.
Also - watch for pad rotation and pad stalling. I personally find the most effective paint correction with free spinning tools of any brand or throw is with both pad oscillation and pad rotation.
There's a YouTube video with Todd Helme, myself and Jason Brennen where Todd gives tips and technique to maintain pad rotation.

Enjoy it while it looks good. If you notice it again when the Uno Protect wears, come back.
