Hello.
I have a 1997 300 Tdi 110 CSW. It has a new rear door, and the four doors up front are in very good condition apart from the usual corrosion at the bottoms. I will replace them in time when funds permit, but for now I’m thinking of repairing the bottoms with some kind of epoxy putty like this https://antel.co.uk/popular/10-epoxy-putty.html . I would do this along with a good spraying of Dinitrol or similar in order to get a few more years life out of them. Has anyone else done anything similar? I know that the corrosion will return, and that it’s a bodge, but I can’t afford to have them repaired or replaced at the moment. If anyone has done anything similar with a modicum of success I would appreciate a bit more information about what materials you used etc. Thanks in advance, Pete.

Thanks - useful information. In what way does it make things worse?

My 2003 front doors were rotten in the bottom corners and along the bottom edge under the door seal. Striped everything off, door card, water sheet, drilled out seal rivets to remove seal. Treated bottom box sections with por15 paint. I used dintrol rc900 followed by 3125hs cavity wax on the internals. Fitted new bottom seals. There are a few extra corrosion holes from the time but after 4 years there is still no rust and the doors are holding up

My previous 110 was a '84 V8 PUP.
It had the same corrosion problem. One of my colleagues is a composite guruand he helped me with this problem. What we did was to cut out the affected area without weakening the frame. If frame is affected you can build a support that can be installed after the repair. File the skin on both sides so that it makes a knife edge. Then you apply the fibre glass in layers on both sides with resin. Use the finest weave possible. Apply peel ply on both sides and clamp area to create a compressed "sandwich". Afterwards sand down and paint. This worked really well, I did this in 2004 and when I sold her in 2012 it was still perfect. |

I had a similar situation but at the bottom corner next to the door. I had a hole about 50p size and a bit of corrosion around it. I cut it out and made a piece from aluminium to fit. I then used some j b epoxy weld to stick some flat bar across the back of the hole. I then used same to stick the aluminium piece over the top. A thin skin of upol filler, prime and paint. If it lasts 2 years I’ll be happy but for now, you’d never know I’ve done it
I was in a similar position of not wanting to spend loads of money on it at the time. The rear quarter has other bubbles and stuff going on so will want replacing one day. Was a bit of a lock down project. |

Some useful suggestions there. Thank you.
I’ll have a go and post results when completed. Pete. Drink Coffee, Talk to Strangers and Take Photos. |
