***Disclaimer***
Assuming that we are talking about the same product, I've owned a similarly branded product for several (>5) years now. Mine don't reference the Perma-Seal (which down here is a "polish/sealant" product marketed at our state Fair). The ones I own are stamped "Made in Germany"

The only similarity to the Absorber is their "thirst". These towels are constructed from a celluose fiber source, and unlike the Absorber, the have a nap.
Because of other toweling products that I own, I rarely use them for drying vehicles paint. On the rare occasion that I have used on for vehicle drying, the blot method seem to work the best. I do keep one in each vehicle to pick up any accidental spills, and use them throughout the house. Excellent product, very durable.
