I promise you this:
when I wash a car, I don't wear Warrick Capper shorts, nor do I "drape" over a car.
Heck, if it's a Trans-am and you can get it to Padstow and if it ever stops raining, I'll wash it for free.
Last time I did a proper cleaned up my Formula, it took me three days. 1 day vacuuming and do-odorising, 1 day cleaning, wiping down with a chamois (now using micro-firbre cloth) and then polishing it and the final day doing the plastic trims with Gold Class trim...
Can't promise you the same treatment, but I'm happy to wash it. It's about the only exercise I get now days.
