If you're going to apply 303 to waxed or sealed surfaces, it might be much easier to wait a week or so after application of the wax/sealant to allow it to completely dry and "outgas" all of the petroleum carrier before trying to "wipe it off with a water-based polymer. JMHO/YMMV
Spot on! Drove me nuts trying to get 303 to work streak free after i waxed. Finally i regulated 303 to the tonneau cover protectant, life is much more stress free after that...
