Starting to tackle the seam rash

[Jonnyb416]

As I move onto repair the offside of my van I won't be needed as many replacement panels but I will need to master the art of de-rusting seams.
This is what I started with today. Jon.

And a close up

Now these seams weren't the worst so ideal to practise on.
All I did was scrape out what I could with a screwdriver then attack with a wire wheel on my drill. Wasn't too hard.




Applied some vactan




Then covered in etch primer




Any advice or tips welcome
I did get behind the seams where possible and treated with vactan too.
Will tackle the others another day.

Pretty good going there. The only thing i would say is if you wanted get a stanley knife and really scrape into the seams. Get all the old sealer out of there, but otherwise cracking job.

With this on my to do list, seeing your efforts here has inspired my confidence!

This is what I face next, you will notice the offside sill that was fitted (rather badly) by the previous owner.







I will take a look at this one first

Started to clean away the paint and rust to reveal what condition the metal is in. Jon.

I have 2 questions about this picture please:

1) Where the rust is/was near the top of the seam it leaves a slightly bubbly surface, now should this be ground back to shiny smooth metal or would rust treatment etc be OK? (close up pic further on)

2) There has been a lower arch replacement at some point. The join between seems is closer at the top where the original panels were and larger where the newer panel is. So... should the gap between seems be minimal or a distinct gap?

Close up of what's left of the rust patch. Jon.

Vactanned up but may need to be ground back some more. Jon.

I would imagine that the pitted area, once sanded back enough would then need the vactan, then filler primer?

[jimpainter]

Carful how much you grind/sand back. What are you useing? If flap discs be careful because they can go through metal really quickly. If you can get a wire wheel in, they remove the rut out of the pitting to an extent then treat it. Ideally though a spot/sand blaster gets all the pitting clean. But as is always the way its never a permanant repair unless the offending bit is cut out and replaced. But if cleaned and treated correctly it should be good for a few years

Thanks Jim. Been using wire wheel on a drill and flappy disc on grinder but only pressing lightly!and taking it easy. Van won't be on the road for a while so won't be using filler etc yet. I have treated and will use etch primer. Used the Stanley knife too. Will be getting stuck in to the rest tomorrow hopefully, the others don't look as bad Jon
