I just finished putting on a second coat of Klasse sealer. I waited approx 18 hours between the first and second coat, now I want to top it with P21s or souveran. Should I wait for it to cure overnight or can I top it now? Thank You!
since wax has some solvent content that could mix with the curing or catalyst in the sealant, I would offer a 4 hour window minimum. 8-24 are maximum and good for less than ideal situations like high humidity and dampness.
