The POR 15 Company, when asked, reported that they did not have test results from coating engine interiors, so they did not recommend using it to coat engine interiors.

While always experimenting & trying different things, I cleaned interiors of engine, transmission, & differential with POR Marine Clean, treated with POR Prep & Ready, & applied one coat of POR 15 which made the interior cast iron surfaces "feel" smooth.

Maybe in a few years if anything explodes, I will have a report for everybody to read ........ until then, everything appears to be working ....... engine oil stays very clean with an oil filter & air filter.
