hi all following on my question about water somehow collecting in my boot on the left hand side between the 2 skins of metal, well ive solved mine!!!
After finally having a dry day i decided to remove the black plastic trim that is sat in the seam on the roof running from front to back. Mine was full of dirt and moisture, so i decided to clean our this channel with brake cleaner, as i did this i noticed to spot welds were pointing skywards and all but 2 held water, bingo!!!!
My water leak issue was staring at me, on my car now i have cleaned the complete channel out and run a good run of seam sealer up the channel and replaced the said black trim. That was well over a week now and up here in cumbria its done nowt but rain and snow and my boot is dry and ive popped the carpets back in..
If your like me and love solving issues get a dry day take that trim off and clean out the dirt and damp and re seal..
