For $279 and 60-minutes time, Truck Trends rustproofing in Tilton, close to Home Depot, will undercoat your full size pick-up in all the right places, underneath, with a thick black N.H. Oil Undercoat that dries to a hard rubber like coating ........ and you will be totally fantastic you did it .....

90-minutes time to undercoat is maybe more accurate to undercoat a big pick-up. Truck Trends does a lot of undercoatings. Seems like this undercoat service has caught on maybe due to N.H. Dept Transportation pre-treating Rt 93 with a salt brine mixture of brine and water before a snow/ice event .......to prevent the snow/ice from bonding to the asphalt surface. The DoT applies dry salt during the storm, and uses calcium chloride in very cold conditions. The coating of brine and water before the storm keeps the snow and ice from sticking to the asphalt and makes it easier to scrape it off with a plow.
The calcium used in the brine is more active than the calcium in dry rock salt and is more corrosive to the underneath of your car. The typical 30-second blast of water underneath your car at a car wash does not do enough to remove the salt brine that eats away at the underneath of your expensive car. ......
