Has anyone used Eastwood's Tin-Zinc Electroplating System? Eastwood claims that their system will plate bolts and parts with a corrosion-resistant protective plating that resembles chrome. Would this be the same thing as the chromate coated bolts that company's sell? Please let me know if you have used this system or have heard any good or bad comments about it. I am looking for a long lasting protective plating for all my bolts, washers and nuts that on used on my cars' chassis. Thanks.
