McRorie's Spray Works Servicing Michigans Upper Peninsula for rust/corrosion prevention

I love gm but their factory wax along with the lack of proper drain holes will lead to a lot of trucks in the scrap yards. Hopefully they ditch the wax soon like they were supposed to for 2027 but I’ve seen contradictory information on if they did or did not.

Lanolin based products offer some real advantages in the undercoating world.

1. Creeps into seams and crevices. It's a thin, self-wicking film that works into welds, lap joints, and pinch seams where rubberized coatings can't reach.

2. Displaces moisture. It can be applied over existing surface rust and damp metal, and it pushes out water instead of trapping it.

3. Stays soft and self-healing. It never hardens or cracks, so stone chips and flexing don't leave gaps for moisture to sneak under. Hard coatings can trap water behind a chip and hide rust forming underneath.

4. Easy to inspect and touch up. You can see through the film to the metal, and reapplying is just spraying over the old coat, with no stripping or prep.

5. Non-toxic and low-hazard. It's solvent-light compared to asphalt or rubberized undercoatings, with no heavy fumes or isocyanates, which makes it safer to apply and clean up.

6. Protects moving and electrical parts. It's safe on cables, hinges, springs, and connectors, where hard coatings would cause problems.

7. Good for fleet and equipment use. Annual re-application is quick and cheap, which suits recurring-service customers.

One of the most important parts of undercoating is ensuring the surface is cleaned before a coating goes on. This salt neutralizer treatment will get rid of any chloride salt contamination causing rust. Road salt and brines contain heavy chloride content which compounds rust at an alarming rate when left untreated.

Needle scaling isn’t necessary on every vehicle, however for best results you need to get as close to the metal as possible. When paints/coatings fail and crack it will trap moisture and salt causing it to rust fast. Also if there is loose paint/coating that the undercoating sits on, as soon as it flakes off it won’t be protected anymore.

Got a few videos from yesterdays job that has every part of the full service. Once I have some more time I’ll clip them together and give an explanation of each part so you know exactly what you’re getting when you book an appointment with me.

Keeping the shop somewhat clean is always a task when there is so much dirt and rust coming off of vehicles I treat.

Quick little video from today’s customer. This is the first time this truck came to me but I knew instantly it was well cared for when putting it up on the lift.
