|
|
A recently restored car for sale, I requested some images and they show the underside heavily coated in a bitumen looking type sealant. This underseal also covered the rear leaf springs which doesn’t seem right to me ?
Alarm bells ringing here? Thank you.. |

I expect someone genuinely thought they were doing the right thing if they found rust on the underside and springs. Cover it in black stone chip to stop it getting worse. Perhaps they thought it would help get through an M.O.T.?
Someone trying to hide serious rot might not have been that naive. Filling rust holes with glass fibre and body filler then a nice paint job is what I call a wicked disguise. |

A closer look at the images showed the ‘gunk’ had flaked off/chipped off from a small area on the leaf spring, showing rust underneath. My search continues |

Rust is not a killer of leaf springs. They are helped with a little graphite grease between the leaves but black goo won't harm them.

Also, if the springs needed replacing, it's not really a deal breaker as far as cost is concerned.
I chose to replace my rear springs but restored the front ones. I was advised to taper the ends (and round off the corners) to stop "digging in".
In the absence of any graphite grease handy, I used corn head grease produced by John Deere. |
