Very surprised by the lack of filler removal by gyeon prep

I sanded with 3K, then polished with medium foam and Jescar Medium Polish. Hit it with Gyeon Prep and it looked pretty good. Hit it right after with Gtechniq Panel Wipe, and HOLY FILLERS BATMAN!!! It revealed a ton of sanding scratches that weren't removed. Be wary of these IPA based prep wipes, they may not be effective.

Glorified QDs is what most are to me. Stick with a body shop solvent like I do.

If I had only known sooner. I was literally shocked when I went over it with panel wipe.

Is this anything beyond standard Wax and Grease remover?

That’s quite a shock. Now I wonder if all preps are like that or just Gyeon?

I seem to like Eraser. Hit it 2x sometimes to be sure. I'll pay more attention. But I do get that "grippy" feel after so I just assume....

Yep. Loads cheaper too. I buy them in gallon size.

What we're you working on?

What type of tool did you use?

What was the sanding paper or disc?

Gtechniq Panel Wipe seems like much more of a body prep solvent type cleaner and its effectiveness on knocking down some fresh LSP’s shows through. IPA (Gyeon Prep/CarPro Eraser) gets me a visually clean wipedown after polishing which is generally what I’m looking for out of this wipedown, no residuals detected through the light source on final wipe. But I’m close to switching over to Prep-All for all post polishing wipedowns for my tests, much more cost effective than Gtechniq and Eraser/Prep. I’d say the main problem for me is I’m addicted to how good Eraser smells.
