I applied DLUX on the headlights of 2 vehicles last night in my garage. I waited 2minutes, then 5 minutes then 1 hour and could never lightly buff it because the MF seemed to stick to the headlight. Checked this morning and actually rubbed some of the DLUX off of one headlight. I know it's cooler weather here, it dropped down to the upper 50's during the night, but shouldn't it have cured by now? I tried re-applying it to the one I rubbed off and now it is streaky. The other 3 headlights look good but will leave a faint print if I touch it. What's up with that? I had sealant on the headlights so I used an APC to clean the headlights and then I did an IPA wipe down before applying the DLUX.
