However when i look closely at the panel seams i can see that the sealant is slightly cracked and in places there are traces of orange where there's obviously a bit of rust underneath.
There is absolutely no sign of bubbling etc, and the only orange discolouration is where the sealant is cracked - no bubbling etc anywhere else.
I'm trying to work out exactly what i need to do about this.
I've read a lot about how seam rust can often start from behind (i.e. inside the van), but am reluctant to start taking out the inside panels etc when there is a chance that a bit of elbow grease with some polish and a decent waxing could be all that is needed here.
In a nutshell, is it likely that this rust has started on the inside or is it more likely that it's started from outside, so a good clean up should do?
(or am i just delaying the inevitable interior removal by posting a hopeful question...
