Our 1999 Revo sort of overheated for the first time after 11 years, it spewed rust that had solid particles that looked like mud coming out from the radiator, so i had to learn the hard way how to flush a radiator, the engine was left really dirty and the wet rust actually made the metal parts sort of yellow a bit, it also made the paint quite coarse so i guess its the effect of rusts acidity.
My Hardest Engine Detail Challenge, it took me 3 whole hours to detail the engine
Here are some before and after pics
