I know about the Simoniz engine aluminium enamel spray paint, but is there any good match brush paint? With the headers off I have removed all the grease with good old gunk and cleaned the front of my engine and it's not too bad as the bike only has 11,000 miles on it. I don't want to remove the engine for obvious reasons. Been told you can use a sponge type brush too good effect by dabbing it on the slightly rough cast finish at the front. Any ideas.
