The blackout panel is 1 part looks, 1 part glare reduction on the hood - from the sun. Also, wanted to play with Plasti Dip.
The reason I was in such as hurry is simple - you have to be with this crap if you're doing an edge. There's no rush if you're painting the entire piece. If you let the Dip dry, it sticks to the tape and come off when you remove the masking tape. ALL tutorials recommend laying down all of the dip in under 5 minutes - all coats.
The only way to get it to work, using rattle cans (it's also available by the gallon for sprayers) is to either have multiple guys working together, or do as much as you can in 3-4 minutes, peel the tape, let it dry all the way, reapply the tape - right up against the edge, and do it again... and again.
For some trucks, there are vinyl stickers for the blackout panels. Land Rover offered (offers?) it as an option. I liked the idea of the Plasti Dip because it (when applied thick enough) comes right off if you get tired of it.
