saw my younger kid checking out the effects of hydro max on my ip camera while he came home.
so while applying hydro max today, i wanted to see how it would do in the sun..on black paint. cool surfaces is no issue, no smearing, etc. in the hot to the touch panel hydromax smeared. but i sprayed a mist of distilled water over the area and buffed with a mf towel. the stacked layer which causes the smearing quickly evened out taking out the smears.
so one can use this in the sun as well. just have a bottle of distilled water in a spray bottle. prima confirms water has no effect in the bonding or curing process.
