Waxoyl for a defender

[pgtips]

After a bit of googling I realize this is potentially a controversial question.... My 1990 TDi needs tidying up. The rear door is corroding (I need a new door), and rust forming around bumpers and visible bits of chassis. Is it worth a Waxoyl treatment (for chassis & bumper)? And if so, does this remove rust to then re-paint (on bumpers), or does Waxoyl effectively become the outer coating?

No. it's supposed to stop it rusting in the first place

Waxoyl acts as a barrier to help prevent rusting. It might slow down a rusty area, but won't stop it. It will remain tacky, so is for areas you don't generally come in contact with.

Good product when used correctly, but often blamed or misunderstood when people expect it to perform magic and defy physics.

So asking on behalf of the op and myself, what would be a preferable solution to surface rust on the chassis and body?

Kind of depends on what sort of surface rust tbh. If it's just coloured, but smooth a quick rub down and covering with WaxOly will be good.

If it's bubbling, then there isn't much you can do apart from sand or cut out the rust and weld in new material. You could apply a rust neutraliser and paint it with one of the direct to rust paints or rust buster paint. Then apply Waxoly over the top to help slow it down.

You can apply the Waxoly directly over the rusted area. But it won't stop it. Assuming the area is dry it should maybe slow it down if it prevents more water getting in, so applying it won't cause any harm. And it can make an area look more tidy. Although it is sometimes used to 'hide' such things. Which in itself is no bad thing if you are wanting to make your own vehicle look tidier, but can often be used as a sales ploy.

There are other products that do similar things, so liked more, some less so. But it's all 6 of one and half dozen of the other really.

Defender folk seem to be getting very excited by a company called Buzzweld selling various products aimed at preserving your chassis. I have never used them but might be worth a look.

If it is light rust and you just want to stall it for now, I would recommend treating the cavities with Bilt Hamber cavity wax and the exposed areas with Dinitrol 4941 underbody wax.
