I appreciate the feedback. As several have pointed out, I realize that nothing will make the finish swirl proof. I'm just looking to maximize my efforts. I've owned a lot of black vehicles, but have never had a garage queen that I wanted to keep as perfect as possible.
I'm getting the feeling that most are recommending something besides CSL/EXO. Is that because of price or performance?
There's a good many number of fans of GTechniq products. I have limited exposure to them only trying two. One was OK, and the other I had trouble with.
It's not that easy to swirl a vehicle that has a fresh CQuartz Coating upon it. You have to be using some pretty poor wash techniques, and filthy towels etc to do such.
Figure about 2 years with CQuartz UK on a regular day to day driver exposed constantly. A Garage Queen should hold up a lot longer.
As Mike Phillips, our forum guru master would advise, your pretty paint is going to be fine for a good while, even if there was nothing applied to it. It's when you "touch it", that's when the "fun" (Damage) begins.
Many members here go to extreme great lengths, not just the pros, but as well the hobbyists, Foam Guns, High Pressure Washers, Two Bucket washes with Grit Guards, the gentlest of towels for wiping and drying, some even use Blowers (Metro Vac) Leaf Blowers, anything to reduce rubbing which will cause sleeks, marring and swirling.
As Mike once touched upon, "swirling" under sunlight looks "circular", but that's not the case. Meaning swirling didn't occur because you were rubbing in some circular fashion, it's just the way the sun or a point source of light makes it look like such. Such is all totally random, and go every which way on a paint finish.
As for the durable coating like CQuartz, there's many videos here hosted by Mike Phillips, and as well you can find such with any specific brand coating posted on you-tube. Cory the USA distributor of CQuartz (Sky's the Limit) also had videos on you-tube applying these coatings I mention.
The more you study, the better your understanding and knowledge will go as far as the applications, the properties these coatings possess, and the pitfalls and mistakes of poor applications as well.
