yep, i play with model planes too.also been involved with a top doorslamer running 500 inch engine supercharged and runs methanol. Yes it is corrosive.we had to clean the injector hat and lines after a meeting. we used crc to coat the blower vanes and inside the hat and reverse flush the pump with good old petrol and sealed it all up till the next time we took it out to play.think we were paying around 180$ for a 205 ltr drum, so its not all that expensive.
