Hotrod, coatings are not a new thing, just one catching one, I think their a good thing especally in tough places like pistons, bearings, etc.I think they work. Some big teams are using them more and more!!! Some small teams are to. (I sound like a dam commercial) but ive begain to use them and ill see for sure!!! I say try using them in one good spot to try to ellaluate them,use more as can afford. thats my curman for the day!!! David.p.s. I lived about 20 miles from swain coatings and talked in person with them and saw the coatings and applications in person ,NICE ...
