No I wouldn't. If you feel them they will likely be stiff and almost abrasive feeling. I found I needed to change the applicator rag a couple times per vehicle and used multiple towels to buff.
Cannot use the applicator rag and towel again, no dice.
If the product is still liquid after this time you might be able to use that, but I'd check closely around the lip for solid particles and not let them get on the new applicator and buff towels.
I will not recommend reusing the applicator pad, applicator rag, or towel after they have been used to apply a ceramic coating. Ceramic coatings harden and cure to form a durable, protective layer on the surface of the car, and any leftover residue or contaminants on the applicator or towel could compromise the quality of the finish or cause damage to the car's surface If you do decide to reuse the applicator pad, applicator rag, or towel, it's important to thoroughly clean them first to remove any residual product or contaminants.
