Day off
Cant get to the van today but did manage to get to Screwfix and Tesco. I picked up sealant remover (as there is a stripe of it all above the windows so suspect something adrift there), removal tool, white spirit, wood hardener and Gorilla glue.
My order of 4 x PU18 arrived from amazon but the double counter sunk screws seem to be on back order
Now things are adding up I also started a basic spreadsheet to keep not only an eye on costs, but to also show you how cost effective a repair is to do it yourself. You can see this from the excel link front page
