Pulling My Hair Out!!!
Relatively experienced weekend detailer. Decent paint correction experience. Good tools, good products. Correcting black old-school base/clear on my weekend only garage queen. Used Flex 3401 with Orange Light Cut LC pad and Wolfgang’s Uber Compound followed by Rupes 15mm, White Rupes Pad and WG Total Swirl Remover. Using 260 Lumen Headlamp with 600 Lumen overhead LED garage lighting. Head on with the lamps, the paint looks like its still wet. Flawless. Back out into late day, low angle sunlight and there are lines EVERYWHERE!!! Point the LED lamp at them and they literally disappear. I need this paint to look PERFECT! I am wide open to suggestions as to lighting, pad, and product.
PS - I have corrected several black MB cars in my fleet over the years and they have all passed that late day, low angel, natural sunlight test. I’m wondering if this isn’t a traditional base/clear finish issue as opposed to the harder Ceramic finishes that I have become accustomed to correcting? Maybe some Old-School 3M Baby-Blue Ultra-Fina on a 3M Baby Blue Waffle Pad for the final buff-out???
Thank you all.

Re: Pulling My Hair Out!!!
Some have said that the Flex forced rotation polishers can’t finish perfectly on some paints. I haven’t used the WG TSR but I’d try a very fine polish with the Rupes white pad. Maybe the Rupes Pure, CarPro Essence, Menzenra 3800, or similar. If that doesn’t work then you might need to use a non-forced D/A.

Re: Pulling My Hair Out!!!
Maybe you have soft paint and need a finer polish like mentioned above. TSR can finish well on harder paint but a soft one could use something finer. Wolfgang Finishing Glaze if you want to stay in that family of products. I’m a fan of CarPro Essence.

Re: Pulling My Hair Out!!!
I totally get what you are saying - and it makes complete sense. My only thought is that the current ‘final buff’ was completed with the Rupes 15, which is not a forced rotation machine. That with the softest white Rupes pad and Wolfgang’s mildest ‘swirl remover’ product - and that left several sections of SUPER light straight lines - perhaps from color sanding??? Again, these straight lines literally vanish in direct, bright white LED lighting. I’m wondering if I need either a touch firmer pad or a touch more aggressive product for final actual ‘correction’ as opposed to simply adding gloss?
This is my first correction of a recent ‘re-paint’ that came out of color sanding and rotary compounding. All my previous experience is in correcting a factory finish.

Re: Pulling My Hair Out!!!
See if the lines are in the direction you’re wiping with the towel. Maybe the paint is soft enough your marring it while removing the polish. I remember TSR gets a bit sticky on soft paint.

Re: Pulling My Hair Out!!!
Forced rotation or the Rupes DA (missed the Rupes, thanks for pointing it out again), neither will leave straight lines so that is likely sanding that didn’t get corrected. You’ll either need to get more aggressive with the Flex but I’d recommend taking a paint thickness meter to see how thick your paint is. I’d hate for you to go chasing some deep scratches that only becomes worse because you go through the clearcoat. If this is a recent respray, you could also TRY to take it back to the painter.

Re: Pulling My Hair Out!!!
I will do my best to get representative pics later today. Car is black. On closer inspection, the correction on all metal surfaces - hood, roof, doors, fenders, quarters, trunk - looks as good as I could ever want. These lines that hide depending on the lighting really only appear on the plastic parts - spoilers, air dam, trunk spoiler. It may be that these softer pieces showed more of the sanding marks and compounding marks. I agree, it pays not to be too aggressive with the clear coat layer - especially on what I have now determined to be pretty limited areas of the car and,depending on the light, are really hard to catch. I’m going to gently touch those areas with Rupes Yellow pad and matching Fine Keramik and then finish up with the white pad and Rupes Diamond (I’ve still got some of each on the shelf - wish they had not discontinued that line).

Re: Pulling My Hair Out!!!
Just a thought in a totally different direction.
I've found many times that direct, bright, white, LED lighting does not show swirls and defects as well as low-angle, yellower, incandescent lighting.
With the bright overhead lighting, or even bright lights on a stand pointed directly at a surface, I find it washes out an defects and makes everything look great.
It isn't until I turn off the overhead LED lighting and put my work light stand at a very shallow angle to the surface I'm polishing do I see the "true" condition of the paint and all the swirls really appear.

100% - I’m beginning to see the advantage of investing in one of those dedicated paint inspection lights like a Scangrip.
