My Renault 5 has been slowly rotting for some time now. I wasn't sure if it would pass it's MOT, but as it has, I'd like to have a go at treating it. Here are some pics of the damage...


Side sill


Wheel arch


Front wing


From the inside



When I spoke to my mechanic about it, he said that if I wanted to treat it properly it'd involve a fair amount of sanding/cutting/welding. I'd love to have a go at this myself, but as I don't have any welding equipment it isn't really an option. The chap said I'd be looking at a good amount of money to get the job done professionally... which is probably more than the car itself is worth!

As a temporary measure to try and slow down the rot, I was told I could just coat the surface with some oil using an old rag. So, I'm wondering if anyone has had any success using this oil coating method? Would it be better to have a go at using some specialist rust treatment paint (such as Kurust) with minimal surface prepartion?

If I wanted to give the job a proper go myself, would it be possible to use some fibreglass kit (like this)?


Any advice or comments welcome! Thanks!

Thanks for the tips chaps. It sounds as though there's no real point going half way... either leave it be, or give it some proper attention. Right?!

Well if I do decide to get cutting I guess I'd have to go the fibreglass route, as I have no welding experience or equipment. A couple of you mentioned fibreglass putty; can you recommend a specific product that you have used and had success with? Also, I can foresee some fairly large holes forming when attacking some of that rust... would I use some sort of mesh backing to support the putty? Or would it be better to use fibreglass sheet in that situation?

Thanks again!
 
My ZX (Unusually for one those) had just started to bubble under both sills. We were going to grind it all off and body shutz them but never did because i bought the volvo instead :D

On your sills i'd do just that and on the wheel arch. The wing wants filling. If it's passed an MOT it shouldn't need welding.

Don't buy glass from halfords, go to a specialist company it'll be a quarter of the price. Polyfibre are a good bet.

Thanks for the tip. Is Polyfibre the kind of stuff I'll be able to get at my local hobby/craft shop you think?
