One bay, one guy, and his name on the door.

Underline Undercoating LLC is a family owned and operated shop on Lapeer Road in Port Huron. We do one thing: we stop Michigan taking your vehicle apart from underneath.

Rick does the work. That is not a marketing line, it is what the reviews say: customers name him, they describe him explaining the process before he starts, and a striking number of them say they come back every single year. One family has had four vehicles done.

The reason is not complicated. An undercoat is only worth what it covers, and covering everything means getting inside the rocker panels, behind the taillights, into the bed panels and along the frame rails, where the salt actually sits. Plenty of shops spray what you can see from the floor. That is the part we do differently, and it is why the job takes about an hour instead of twenty minutes.

We started in 2020 and we would rather do fewer vehicles properly than run a queue. Everything is by appointment, everything is quoted before it starts, and nothing gets sprayed that you have not agreed to.
