AlBoston,
How long has it been since you last applied a coat of
SG? Perhaps it's time for a fresh coat. Although SG will last quite a while, it slowly thins out (like all sealants). Perhaps your coats are no longer thick enough to hide the original imperfections (if you had any!) when you initially applied SG.
In addition, no matter how careful you are, there is no way you can expect to regularly detail your car (wash, dry, qd, etc) without causing a few scratches here and there. A fresh coat or two of SG should pretty much wipe out whatever swirls you put on your sealant layers.
As for carguy not believing that
Klasse SG can act as a buffer against swirls in your clearcoat....no offense to him, but I prefer not to give too much clout to opinions based solely on guess work as opposed to opinions based on actual experience. But then again, no sealant in the world is going to protect your car from swirls if you're washing your car every 2-3 days like he does. According to a former member here (beau), washing your car is the number 1 source of light swirls on your car.
I've switches sealants before on my black car and the simple act of removing the sealant with a non-abrasive cleaner did a great job at removing some pretty ugly looking imperfections. So YES, a good percentage of your swirls are probably in your sealant!
