TST

Punched my Silverado in Elk county PA with the TST 5K lifetime rust proofing. My vehicles rocker panels, frame, & wheels wells are all rusted out at the 7 year mark. TST denied the warranty claim due a loop hole they created. I have the receipts and a rusty Silverado from TST 5K. Do not purchase this solution or work with this company

I had my Truck done in January of 2017 with paint protection, undercoating and rustproofing, and interior protection. It still looks like the day I bought in 2016, Dirt does not stick, after this month of February, snow, salted roads, brine, it was pretty filthy, it rained the other day, and it looks like I washed it, it hasn't been washed in over a month. Great products worth the investment, highly recommended and will be done to every vehicle I own from now on

I had TST applied to my new custom ordered Volvo XC90 last year at Bobby Rahal. The finance lady assured me that it would provide protection against environmental hazards like rain drops, acid rain, etc. Shortly after buying the vehicle, the water spots from rain after parking at the airport almost a week wouldn’t come off the paint with washing or using the supplied cleaner. Dealership took care of it. Continued having similar issues and also found out the product doesn’t protect against bird droppings. Issues were fixed but the product doesn’t protect the paint. Regular waxing provided better protection than this product and that’s what I’m going to do moving forward since this product doesn’t work. I cannot recommend this for the exterior based on my experience. For context, the vehicle

Terry moon had my 2021 Toyota Tacoma rust proofed in2021 and redone in Feb 2025great job great people I will be back

Well worth the investment for any owner made to their vehicle living in a Pittsburgh climate. TST keeps our entire fleet looking like new with their paint guard, rust proofing, and undercoats.
