Hi, I'm currently making good progress on my 1969 mini and just need some advice on the channel that runs at the top of the fender where it joins to the body. Originally on my mini it was completely filled up with bog and painted over (which had cracked). Whilst doing the body work I've cleaned it all out so there is now a channel that can be seen. I'm just wondering if there should be a drain hole in this channel? Should I just drill a drain hole in it so any water will go into the wheel well or should I just fill it in slightly with some sort of flexible filler or something? Currently it doesn't drain, I've had a look underneath and can't really see any drain holes (only had a quick look though).
I'm fortunate the rust hasn't got in there yet so I'd like to fix it so it won't cause any issues with rust in the future. I don't have another mini to look at for reference so any help would be appreciated.
Thanks
