Under sealing

Look at buzzweld.co.uk
They have companies dotted around not the cheapest but probably the best

Hi all thank you yes was thinking of buzzweld

PCM in Cheltenham seem to get good feedback in various quarters like mini forums etc. Not used them myself though.

A while ago I wrote a dedicated wiki article on the topic of underbody rust remedy and prevention, to the best of my current knowledge.

One thing about this topic is certain - there are dozen wrong ways to do it and only a couple of correct ways. The other certain thing is that some methods which appear quite OK can actually make the situation even worse in the long term.

I hope that it contributes to the awareness of this.

Hi thank you will have a read

My tuppence worth - Every time I see underseal on a vehicle I wonder "What 'cowboy' applied it and what is hiding underneath the coated surface"?

It's topic that folk can become quite emotive over and if done correctly (thorough surface preparation and application) can be an asset. On the other hand I have personally seen it used to cover a multitude of defects and seduce a buyer into thinking they are purchasing a sound vehicle with a long lifespan - when in reality the vehicle is fit for the crusher.


I've done a few DIY applications in the height of a sunny summer - rather messy, not technically difficult and I knew it was a thorough job (because I did it). Cleaned the underside thoroughly (including equally thoroughly drying off/out over a couple of very hot days) and sprayed with old fashioned Waxoyl - including flooding box sections on the chassis and avoiding exhaust system and brakes. After 18 - 24 months I 'topped up' a few areas where needed and after that it was just an occasional squirt where tall vegetation or debris had made contact with the chassis legs.
