Does Platinum Rust Protection oil undercoating creep and migrate? Well, see for yourself, after sitting overnight it has crept out a little bit, after only 10 hours or so. The inside of the frame rails were fogged, and that’s where yesterday ended. Today we pick up where we left off.

So winter and those brines they dump all over the road are getting a little closer, I know, nobody wants to think or talk about that. It’s August.
And we are booked up until October.
Just wanted to give everyone a heads up, if you want your vehicle taken care of in October, now would be the time to get on the schedule. September is full. Openings start the 4th.
