Sweet beads, Dan! Great results. As of today, I can attest to DG AW lasting 3 weeks so far for me. Applied DG 501 Marine Polish, and AW, 3 weeks ago. Washed it past 2 weekends and used DG 521 Marine Detail Spray to the body after wash. Personally, I think that DG 521 gave my SUV a better shine than CK Quik Shine. Didn't use DG 521 on the roof, just to see how AW held up without any additional boosting sprays. Had a few rainy days. Heavy rain today, but AW is still beading well.
