Tip for guys looking to do their trucks/parts.
Before my raptor I had a JK Wrangler and I went into have the entire thing line-x'ed. It was the first time the shop had ever done an entire vehicle so I was able to stay and help with the whole process..
Bumpers- Remove from vehicle and 360* spray the entire thing, holds up better this way.
Fenders/flares- Remove flares and spray separately and cover under where the flare will sit, make sure they spray inside the engine bay where the fender wraps in as well for best coverage.
Doors- Spray the door jams as well and the metal showing on inside of door.
Plastic- It will be fine if its not a moving part (Handles,latches, ect..)- just make sure to really rough it up first.
General- Remove as much trim as you can for best coverage and durability, where we didn't remove the trim and just taped didn't hold up as well compared to the other areas.
Just my quick .2cents for anyone that cares or is interested.. or ill go
off haha
