It's been awhile since I've been able to visit Autopia and this is the first post that popped up. Anyway, Bill, Lackfinish is different. It is geared towards those folks who can't polish their car at home but rather they use a self-service wash box. After you rinse the shampoo and the paintwork is still wet, you spray Lackfinish on the surface, wait a few seconds and rinse again. So again, you spray it on wet paintwork. While Lackfinish doesn't polish the car, it adds depth and gloss and provides a mild polymer protectant like Raindance Shampoo (Perls Shampoo in NA).
However, JGV, have you tried it as a dry QD? Works very well IMO--I know, I'm slightly biased. But I really am happy. Great cleaning effect. Great gloss enhancer and it adds that polymer layer still. As with all QDs, it works best with a microfiber. It also works well in direct sunlight.
