I know I've said this before but I think the shinest part of a truck should be the body
If you make everything shine truck just doesn't look right.
I use 'Used Car' detail paint.....Do have to etch stuff's kindda waxy don't have to prime...nothing
It drys over anything and you don't have to look like a diver to safely apply it.
When done you can strike it with a hammer and it doesn't crack chip or nothing.
I used to use Oscar's I still have a gallon mixes 20:1 with water or lac. thinner
20 gal goes a long way!
As long as it does I'm not lookin for anything else.
Talk to your local detail or radiator shop I'm sure the still sell something really good and really easy
Just my idea..........
