I'm an owner of a 2002 GC Overland with the 4.7 HO. It dropped a valve seat and basically ate the #8 piston and sleeve. I've since gotten it remanufactured at a local machine shop and I'm ready to install the new rebuild parts.
Before I finish the rebuild, I've been researching the benefits of a new technology now available for the Saturday mechanic: Ceramic Thermal Coatings. There's a company here in Oregon that is well known throughout several industries that has a product which can be applied by anyone who can follow their directions. http://www.cerakotehightemp.com/finishes/
Does anyone here have any practical experience or notable research with these or similar coatings on piston tops, exhaust ports and cylinder head chambers? I'm seriously thinking about jumping in and seeing if it works as advertised. Any relevant reply would be appreciated.
