Hi David,
yes I thought about it, but I don't know what sort of the condition the car is underneath. That said it's had 2 MOTs in my ownership, and no advisories for corrosion, so fingers crossed. I think if I had a garage I could keep the car in on axles stands I might consider doing it myself, but I was talking to a neighbour who bought a Transit, and one of the first things he did was spend about £300 getting it waxoyled. I'll ask him where he had it done.
Got one quote today that was around £500, which is a tad more than I wanted to spend!!
