We had an excellent experience with KB Undercoating & Rustproofing Services. They were able to schedule us the day after Christmas and communicated clearly and promptly throughout the entire process. Being in Pennsylvania, where winter road salt causes serious rust issues, we wanted a quality solution, and their Woolwax undercoating was applied thoroughly and professionally. The attention to detail was outstanding, and we feel confident our vehicle is well protected. Highly recommend and definitely will be back for recoats on the Jeep and looking into scheduling our other vehicles!

Clark squeezed me in a few days after I called, sent before and after pictures, and gave complementary air fresheners for my rear view mirror! Excellent work and awesome customer service!
