I'm after a steer in whether I need to have some remedial work done on the area beneath my nearside door, in particular the join between the wing and the body. The beading is bulging in a couple of places and has quite a bit of wet grime between the joins. The expensive route would be to have the wings removed, a good clean up the beading replaced. The other options I'm considering is squirt a load of acf50 in the join, and repeat before washing, or apply some clear silicone sealant in the join to keep any water out. Or something else that you guys suggest. Is it a scenario thst will only get worse over time?

Can you post some pictures?

Any advice on uploading photo's. It says I can't upload any bigger than 1000 bytes?

I'm afraid I can't answer your question Leroy but, please don't use silicone sealer.

If you ever need to get that area re-painted the silicone will be a 'mare to get rid of and it can cause real problems with the paint.....

Agreed, plus it will never seal well enough to stop moisture getting in, & once in will partially trap it & slow the drying out, often accelerating corrosion

Unfortunately you may have a major problem, it was common on older cars to rot the wooden rocker and rust the outer metal skin.the only treatment is to remove the rot. But .I hope it's not that serious.

It's a 2004 roadster so it won't gave the rust issue with its aluminium body. I've have a thin wooden skewer along the beading and scraped out a load of grey/black greasy slime so hopefully it'll dry off. Don't think there's any rot issues, but just want some advice on whether it's a wing off job, or whether a good greasing either side of the beading will fill in and crevices/recesses to keep the water out is a sufficient remedy.
