Not going to be doing that, but the theory is sound on a less valuable vehicle or out of site but not the bonnet.
Back in 1985 having just got shot of wife two, or was it the other way round I needed a pace of life change, having just bumped into an old mate of mine and first wife, he'd been doing a bit of light haulage courier work, said it was a doddle and I thought I could so that, so splurged out on a really tatty Luton transit, it got the Dulux roller treatment, and I started doing removals, mainly DHSS, which was a bit dodgy as I was signing on at the time, briefly anyway I was billing the office next to where my money came from., and I've had two purple mini both rolled in silk vinyl.
Wish I still had the Tranny Andy and I (my partner at Triple S ) had so much fun in that old heap, the Corsair V4 engine eventually died on the M62, so one diesel front panel and 2.0 OHC Cortina engine later and we were back at it.
