Rust Spots Under Paint.

[BCNR33GT-R]

Hi I have a couple of rust spots that have come up under the paint.

What should I do with it to get rid of the nasty shit, could i fix it myself or rust repairers?

Depends on your paint skills and expected results!

If it's say in the engine bay or under the boot lid and you're not too fussed about a factory appearance then definately do it yourself. If it's part of a large panel (around rear window or some other fiddly bit) then I would probably take it to a good panel beater that will cut it out and repair it properly, not just bog over the top of the rust and repaint it.

Again if it's not too bad you may be able to do the prep work yourself and just get it repainted by someone else. Might save you a fair bit of cash that way. If you've got a welder it's surprising what you can do. I've welded a fair few sections into my Datsun and it is surprising what result you can get with some patience and steady hands.

Yeah it's above drivers window and couple smaller ones down the rear quarter window the only rust it has.

Deffinatelly will have to get someone to do it as window may have to come out also.

Do you know any product that will make it stop rusting in those spots?

Cheers ewan

There's some incredibly good rust removing compounds available for surface rust. 3M do a good product, there's another one I cant remember the brand name but Super Cheap sell it (in a small black plastic container with a handle on top, like a mini oil container).

You put the compound on the rusty bit, leave it for 10 minutes, wipe it off with prepsol (oil and wax remover) then with a damp cloth. Repeat if needed. Provided the rust isn't too deep it works awesome. I did a fair few spots in my car (plenum chamber near bonnet hinges, under the boot seal and behind the inner guard liner. Came up pretty good. Provided you either paint it, treat with a rust inhibitor or fish oil, it should keep the rust away in future.

It's a constant battle!
