    CarPro Eraser Residue!?

    Hello AG community!

    With a bunch of recommendations and guidance from you fine folks I finally got all my stuff together and found the time to do some paint correction on my car, 2011 Subaru Impreza WRX in dark metallic gray.

    I did the whole car using a GG G9 w/5" backing plate. Primarily used white foam Lake Country 5.5" CCS pads and Sonax EX 04-06. I was really really happy with the way things had been coming out. Test spot looked great so I did the whole car. I have some deeper scratches and random other spots I couldn't get out and since this was my first time and Subaru clear coat is notoriously thin, I wanted to stay away from anything too aggressive.

    Now, onto my issue. As i polished I was using Cobra Gold Plush MF's to wipe up the compound, it came off pretty nicely and easily. After doing the whole car i gave one more wipe all the way around with a fresh MF (I used probably 5 before this during the polishing) and then grabber my CarPro Eraser and started sprayign and wiping. I decided to grab my flashlight and really examine my, I thought was, great work. Upon doing this I noticed that I had what appeared to be crap loads of tiny, hard to see micro scratches. In normal garage light and even with a fluorescent work light everything looks so shiny and deep and pretty, but at just the right angle with the flashlight you can notice all the marks. I have ruled out holograms from polishing because they are very straight scratches. I should note that these MF are brand new, washed in my washing machine alone with Blackfire MF cleaner and then put immediately into a brand new plastic tote until being used today. I have discovered that these marks go in line with the direction I wipe with the Eraser and, when wiping perpendicular to a previously wiped spot the old lines are no longer visible. I tried this with both the Cobra Gold and Gyeon bald wipes, same result's.

    I have read mixed things about Eraser maybe leaving a residue? But then others say absolutely not. I was so excited for how good everything came out and this issue is really bugging me. My next step is CQuartz 3.0 but I don't want to jump into that until I know my paint is clean and mostly swirl scratch free.

    Sorry for the lengthy post and THANK YOU for reading!

    You could be experiencing towel marring on soft paint and not so much the Eraser.

    So you were able to wipe the lines away? If so, reapplying eraser should show residue if it was actually that? I’ve only used 16oz of eraser but never had residue, even on gloss black paint.

    I was able to rule out the Eraser as I had not wiped down the roof yet and it has the same markings. It appears it likely is towel marring, how I can I avoid that? I thought I was using quality MF already and I took every precaution to make sure they were clean and soft (tumble dried with no heat after washing).

    Are these towel marks going to be as visible as normal swirls?

    I suppose I don't exactly know what the compound consistency should be when I was cleaning it off in between sections, it wasn't dry at all, but a thin layer greasy layer left over, am I using too much compound?

    Re: CarPro Eraser Residue!?

    Im not a MF expert in any way but are those towels 70/30?, could it be the edge of the towel that is marring the paint?

    I used to have an STI in WRB and that thing got marred with just looking at it, Subaru paint is pretty but a headache to work with

    Don’t go light with the eraser, get good coverage on the panel and let it sit for a min. Use two towels one for the initial wipe, second for the final buff. Don’t use pressure either.

    The Gold Plush are 70/25 but the edges are finished with microfiber as well. But I also have some Gyeon Bald Wipes that don't have any stitched edges and i've been getting the same results with those.

    I'm thinking the EX 04-06 may be too aggressive for the soft clear coat?

    Soft paint is hard to work with. This is where a primer polish often comes in handy if going the coating route. Something like CarPro Essence since you are using Cquartz. A prep wipe is not required with even a light prep wipe is ok since the silica within the primer polish cures if you let it sit overnight.

    Try the bald wipe. I am not the biggest fan of the gold plush with panel wipes. They seem to be more grabby.

    I’m not a fan of those cobra yellow towels. I use them for interior only.

    Once I started using Essence as a finishing polish this prep wipe became much less important and I do it lightly mostly to remove dust from sitting overnight which I prefer to let Essence cure.

    Welcome to the world of soft paint. What is your end goal for LSP? Coating, sealant? I also second using a product like Essence from CarPro. Also don’t put too much force on your towels while wiping and don’t wipe too quickly.
