Waxoyl into inner sill?

[Paul Baldwin]

If you're worried the Waxoil's too thick spray something thinner down there. Old engine oil and diesel is the old trick. The diesel is that thin it'll soak righ into any rust, even in a seem. Parking it somewhere for a bit afterwards is the only problem. If it's wet you'll leave rainbows everywhere you go
I've just bought an SRDT as it happens. Had a couple of 405's over the years and they've always been good to me
