Maybe Cquartz does just suck. Idk. Not my area of expertise.
GREAT question! So you’ve got your coating applied on your section, right? You’ve waited the correct amount of time to wipe it off, and you go for it. If you miss a spot of residue, or your wipe-off towel pushes it around and leaves a little behind, that’s a high spot. It’s extra coating that doesn’t need to be there that then hardens into an imperfection. High spots are why you MUST have good lighting when doing a coating. If your lighting sucks, it’s super easy to miss one or two. For polishing, you want a direct reflection of a light source on the paint. You’re staring at the intense reflection looking for scratches, swirls, haze, etc. When putting on a coating, you want flat, diffused light. My recommendation is to brightly illuminate the wall behind you when you’re doing the coating. Makes spotting high spots easy peasy.
:thankyou:
And now...I get it. I had a tiny spot on the edge of the side mirror on my C5 that looked like residue that wouldn't come off. I clearly missed wiping that tiny section, and I suspected that's what it was, now I know.
So when a coating is more "difficult" to apply, does that mean the high spots are harder to wipe off so it needs to be applied more smoothly? Or is the window during which they can be wiped off easily shorter? I know you said you'd need to bust out some mechanical force to correct high spots, but is that because you missed wiping them when it was easier or is it just never easier...thus needing closer attention to detail and experience?
Sorry to riddle you with questions, I've just always wondered about the difference between retail and professional coatings. I tend to consider myself an advanced DIYer, and whenever I asked these sorts of questions on other boards the responses were just "let a pro do it" or "pro is just better" or "don't even attempt pro as DIY". OK fine, but WHY?
Yes, I was that annoying "why" kid.
So lets go with Crystal Serum Ultra, which is pro-only as an example. It’s harder to wipe off. You need to use more elbow grease, wipe off towelswith plenty of “bite” (short-pile terry or pearl weave), and you need to use 3 different wipe off towels at a time. First wipe gets the majority of it, second touches up any remaining high spots, third makes absolutely damn sure there’s no residue left. Ultra also needs to be wiped off in a more precise time window. If you wait a little too long, it’s gonna start fighting you and get “grabby.” Next, if you DO miss a spot with ultra, you have very little time to fix it. An hour if you’re lucky. With something like Gtechniq C1, if you see a high spot the next day out in the sun, you can get it off by re-cleaning the surface and reapplying C1 over the problem area. The new product will reactivate the old product and let it wipe off fine. If you fuck up with Ultra, you need to compound it off if it’s early or wet sand it off if you didn’t find it for a day or two. Ultra will also COMPLETELY ruin your wipeoff towels. All 3 of your wipeoff towels (perhaps x2 for larger vehicles) have to go in the trash after. With C1, you’re probably only throwing away one towel.
So, consumer grade coating oopsies can be corrected by the consumer. Pro grade coating oopsies can only be corrected by the pro usually.
Additionally, when you’re paying for an expensive coating like that, you want the warranty with it, which is why it’s worth getting a pro to do it.
On top of all that, a bottle of crystal serum ultra is double the price of a bottle of crystal serum light.
