Removing rust stain runs from paintwork

canhefixit

Can anyone suggest something that would remove the above?

I have small little rust bubbles above the window of my lwb mk1 connect and today after getting it washed they make it look bad, so anything to take the look of it as it dont have to be perfect

cheers

Dab some rust remover on it to kill the rust, then get a paint touch up kit to match the colour from Ford. It'll have paint and lacquer. Just dab on a bit of paint, let it dry. Maybe a second touch up of the paint, then when it's dry some lacquer.

Oxalic acid will remove rust stains, try a marine supplies place.

Depends how long you want to hold onto the van. Bubbling paint means the rust has gone through the metal and made it porous, hence the bubbles.

You've two choices really CHFI, cover up or kill. The "rust remover" stuff will slow down the rust from progressing, but it doesn't remove it. It chemically changes the very top layer of the rust into a more stable compound, the rust continues on underneath, albeit at a slower rate. Doubly so if it's gone through the metal. If you can access the back side of the panel and hit the rust treatment there that would slow it down more. With a bit of sandpaper rub away as much of the rust as you can, then hit it with the rust killer. Then the touch up paint. Should last a year, visually anyway. If you want to kill it dead that means removing all corrosion and getting back to sound metal. What rust you can see is almost certainly at least double in size under the paint, so you end up removing more metal than you bargain for. Which then usually means breaking out the welding gear, priming and painting the whole panel. Pricey.

This is a work van so the finish dosnet have to be 100% perfect but i do want to address it before it gets any worse and it is a bit of an eye sore tbh...can anyone recommend a good rust converter product? i seen stuff called krust in halfords but is there any better ones?

I dont mind sanding back the rusty bubble spots and patching them in, its just to take the look of it really and to prevent it getting worse, a mate had great success using a white applicance spray on the bonnet on his badly chipped transit, he sanded it down and gave it couple coats that was about 2 years ago and the bonnet still looks like new today

Rust converters like kurust just don't work. When you paint it on it turns the rust black but if you scrape the kurust off again the original rust is still there as active as ever.

A good rust remover like this will remove the rust plus the rust stains running down on the paintwork. You won't have to do any further treatment to where the rust stains are on the paintwork once they are removed, just wash the gel off is all. You'll have to protect the metal where the original rust was though.

When applying the gel make sure that the weather isn't too cold as it's not effective in the cold. Apply cling film over the area the gel is applied as it stops the gel from drying out and will cut down on the amount of times you have to re apply the gel to the area.

apply this when the rust is removed back to bare metal to protect from any further corrosion. Make sure it's applied directly to the metal and then apply the top coat afterwards. Brushing it on works better for small repairs. Before applying make sure the area is nice and clean and that all the rust and the gel is removed.

Scrape the heavy rust off and apply the gel.

Sheesh when I viewed that photo my first thought was has NASA released another flypast of Pluto pic.

The Bilt Hamber Deox Gel stuff is fantastic. Been using the BH stuff for years. Far better than Krust, or Waxoyl too for that matter.

Though you need to leave the Deox on for longer than the bottle label states. Like overnight and as JB said not great in the cold(should be grand now). Don't be too shocked that what you're left with is a panel with holes mind you. Don't ask how I know that…

IronX will also remove rust stains from paint.

No point paying extra for ironX though when the rust remover gel will do the same job.

White vinegar will do the job too of removing rust stains from paint (and if you can submerge a part for a fortnight, a pretty good job of removing rust full stop). JB nails it. Clearly as much, nay more a better informed rust paranoiac as me.
