Lower door blade

Post by Look595 » Sat Sep 28, 2019 8:45 am

Question,
Although I’ve no issue at present, is it worth removing the lower door blades to clean/wax and replace to prevent any further issues and inspect current state.
Or am I asking for trouble removing, breaking clips/unable to re-fit correctly ect.
I know there’s two retaining screws to remove then simply slide back....easier said then done I’m presuming.
Anyone done this with no problems encountered?

It’s very easy to remove as long as they are still in good shape, the process is just as you described and its worth doing to make sure they are cleaned out thoroughly periodically, the accumulation of road grime and gunk helps the inside of the blades rust over time and will cease to look smooth but wavy, they are not cheap to replace when you consider the cost of the part plus color matching it with the rest of the car.

Replaced my drivers door one a few weeks back and it came off quite easily you just need to pull it backwards after removing the two screws. Mine was past saving so had to buy one along with some rattle cans for paint and lacquer. Gave the door bottom a good clean and a liberal dose of WD40 around the locating lugs before fitting.

Definitely worth doing.
Mine were delaminating a bit and I applied epoxy and clamped them.

Did you get a decent colour match/ paint finish doing it with spray cans?

I had an issue with my passengers side door blade. The steel strip that was inside it for rigidity I guess, started rusting badly and lifting blade away from door. My assumption was due to salted roads in England where car was from. Don't know why Audi didn't use stainless. New blade from Audi was hideously priced so decided to try and fix old one.
Took it off, put it upside down on some carpet, gently popped out plastic track that the door studs locate to that fits inside rusty bit. Then slowly removed rusted section inside blade with a mixture of longnosed pliers and chisels etc. It's fiddly and took a while.....try not to bend the blade too much while doing this, you don't want a crease in it.....Then glued plastic track back into blade with gripfill builders glue and clamped.
Put back on car and looks mint. Saved a few bucks for anyone with same problem.

So...removed the steel strip then replaced????

Assuming the answer is yes, I think i’ll be doing this soon.

Hi mate, yeah surprised myself especially with it being Phantom Black. Will take a pic when the car is cleaned. Used Halfords paint and lacquer as this has always been good to me in the past and the nozzles don’t clog easily which is always a pain on cheaper spray cans! Just need to take a bit of time especially with the prep. Left it a week to harden and used some ultimate compound to finish it off

No. The strip taken out completely. It's moulded into the plastic.
