David Uses Lucas products in ’60 Falcon with 400k Miles

I am the owner of a 1960 Falcon, with 400,000 miles. I recently added 3 of your products to my engine, transmission, and fuel system. Please know that my vehicle now runs better than when it was relatively new!!! Really amazing products. You saved me a bundle of $$$ and heartaches. Now it's a pleasure driving my car.

Casey Franca uses Lucas Liquid Polish in 2005 Roush Edition Ford Focus ZX5

Since I purchased my Focus in July 2005, i've spent a small fortune on waxes and polishes looking for that one product that gave me the results I wanted combined with ease of use. I finally found it with your Liquid Polish. You guys are in a whole new league compared to those other guys (Meguires, Mothers, etc.). I've gone from taking about an hour just waxing my car to being able to wash, claybar (if necessary), and use your polish to shine her up and buff her in 30-40 mins. And best of all, it didn't feel like my arm was going to fall out of the socket afterwards like with those other waxes. Forget Mr. Myagi and his "Wax on, wax off", give me a wipe on, wipe off instead. I sincerely hope you folks are going to eventually get this product out into the marketplace, because when what I have runs out, I'm going to need to know that I can get some more at the Pep Boys around the corner. Heck, i'm already telling family members and a few close friends to keep an eye out for it in the stores! Feel free to use this testimonial any way you wish. I am that confident and happy with you guys.
