It’s nearly 4 years since I last had a good session under the rear of the car. The waxoyl I put on them has done a good job but definitely needs doing again.
I removed some light surface rust from the edges of the subframe where the original paint is thinnest. Kurusted the areas then painted over with hammerite. Them a good layer of waxoyl over the whole lot.
I’ve seen cars where the underside looks like new but mine is good but hidden under a load of protection against rust.
I replaced the original rusty screws used for mudflaps and wheel arch protectors with stainless steel screws. Also I cleaned up the shockers back to their original yellow.
Overall pleased with the results and now ready for some wet weather we are bound to get.
