About to fit a new front spring but can't decide whether to leave it open to the elements or to wrap it with cloth tape, Denso tape, rope/cord or use some giant heatshrink? Leaning towards the cloth tape but interested to hear what others have done and any problems encountered.

I reckon it's one of those things where yer pays yer money and takes yer choice. I went for Denso tape this time around, the appearance of it pleases me but I'd hesitate to say it's better than something else. It's immensely sticky though, and tricky to apply once the springs are assembled without making a horrible mess.

I tried stripping , cleaning, greasing and Denso taping the springs many years ago and some time later I broke a spring leaf. On stripping it down the spring looked like it had been at the bottom of the Manchester ship canal for half a century. So I paint my spring and oil them.

I guess it's down to what you actually do or intend to do with the car. Mine is a road going car only and generally only goes out in fine weather. My springs are painted and oiled. If you're into trials or other harsh activities bound springs may be beneficial, but as Dave says, the binding might keep muck out but it can also retain moisture which is not good in the long term. My car still sports its original, naked front spring (without it showing much in the way of wear) so I must be doing something right.

This is one of those recurrent topics. Like crankshafts springs develop long cracks before failure. Whilst not so serious at the front a failed rear main leaf can be. Exposed, an occasional glance will often locate any crack.
Corrosion promotes fatigue but oiling the springs may prove too lively for cars with standard shock absorbers.

I Denso taped mine when new a couple of years ago. But there was a long discussion on here a while back with some pictures from, if I recall, Robert Foreman, of his denso taped springs having rusted away underneath, so I am wondering if I did the right thing.
