I've been intrusted to clean and polish a stunning yellow 1952 PA18-A when it goes in for it's annual this month. I'm brand new to fabric aircraft and don't want to botch the job. I know it's probably simplistic, but would hate to muck it up by using the wrong cleaning materials or trying to buff and polish a plane materail that doesn't like buffing and polishing. Wouldn't want to mess up my chances of getting to fly it again next summer.
