Hi. In last summer I welded the exactly same spot on my x308 xjr at the rear door arc. Reason why the paint is bubbling is because under that metal plate there is empty cavity. That cavity is filled up with some black nasty wet goo. The goo has dried out over the years and there is moisture now eating up the metal inside out. You need to replace the metal and find out the condition of the sill metal. Sill does continue under the bubbling paint metal. You said that there is filler because someone has replaced the sill. No. It is factory made. Like is the 3cm thick seam sealer at the firewall, inside sill and floor connection corner.. 😄
Interesting. Thanks for letting me know. I did manage to get my Bilt Hamber "wand" insertet through the holes for the screws. I dumped half a can into the cavity until it was spilling out of the sill at the bottom. I know it won't fix it but i'm hoping it will arrest any further spread until next summer!
Yep. The thing is that the sill top part is rotting under the goo. But the bottom could be still intact. I had to replace top portion of the sill under that bubbled metal plate and while there was a gaping hole I could look in to the sill and there were no rust at the bottom. I can sent you a pictures from google photos if you want to see what I mean.
