doesnt really have a drying time. Just need to rub the heck out of it with your hand and generate some heat to "seal" it. I would quickly tape off the blue at the edge along the cheek and dust in some more of that ocean blue to minimize the mistake. I think you'll kick yourself later and it will be a lot harder once the visor is in. Another small suggestion, I think it really helps the overall look of the helmet, use the more accurate 3/32" black striping tape instead of the 1/8". It usually has to be ordered, I found it on ebay for a couple bucks.
