Rusty Door - Advice appreciated!

Post by conmai » Wed Aug 13, 2014 8:36 am

Hi All,

Looking for a little advice on dealing with some rust on my drivers door, its mainly surface rust on the inside, going along the bottom of the door, although it does get quite flakey on the corner of the door (door openeing corner) from the outside there are some very fine bubb ...Is there any recommended treatments I can use to stop it munching or growing, or would I be best getting it to a bodyshop, I'd rather catch it now than leave it a year or so and find the corner of the door has started dissapearing!

Cheers

I am about to do some surface rust work on a sill and am going to use Hammerite Kurust and Hammerite smooth silver direct to rust paint (2 coats)... all available on ebay. Depends if it is paint or the metal bubbling usually indicates the possibility of pitting or holes which might require some filling with a decent filler before the above.

You need to give a ruthless sanding and wire brushing to get right through to the bottom of it to make the best repair, anything loose be it surface rust, paint or bubbling need to be taken right off so a solid surface however pitted remains. Also make sure you sand/wire brush the area so that the edges of the rusty area are solid paint, this helps stop creep under new layers you build up. Doors tend not to be MOT failures but catching it now is a good plan. The more meticulous the longer it stays protected.

In my experience it is always best to work after a few dry days and don't rush the coatings.. let a reasonable amount of time pass before doing the next layer (weather and dryness permitting of course) I used to own a very old car so have a little experience in this I had to protect the arches on it every year before winter came in.

I find it quite therapeutic treating rust. :lol: (well up to a point)

Thanks for the advice, I'm tempted to take it my local bodyshop, the corner on the inside is quite flakey with very minor bubbling (not yet through the paintwork on the outisde), on the onside the metal has deteriated a little so would need some 'craftwork to build back up to shape.... My Bongo also has a non standard paintjob which would also need colour matching too :(

It's often easier / cheaper to find a replacement door from a scrapped vehicle if you can get one in correct colour / decals in good order without rust and dents.

If the rest of the Bongo is rust free, this could be the result of badly repaired accident damage. A new door in the right colour could be the best bet
