Had more time on the van this weeked,rear and side windows out and apart from some pitting the frames seem to be relatively sound looks like a previous repair has been carried out on both rear side windows to so maybe thats why, all wire brushed and vactanned both sides
Then onto the drivers side below the rear window
These appeared after using the rotary brush but the back internal stiffener was badly corroded must have been water lying in the joint causing this at the front
Was trying to cut out as little as i could get away with but the corrosion was more extensive at the back hence the bigger hole
Then cleaning up and getting new metal in
Vactanned and bit of filler to go over the over top to level and finish
