Diff access panel waterproofing

Just a small job for this evening. I decided to add some foam to my diff access panel to try and stop any water ingress into the boot. I won't be driving in the rain normally but you never know!!

I bought two sheets of craft foam from hobby craft for about 70p each and glued them to the back of the access panel. Trimmed it with a Stanley knife and sanded until it was perfect. 

Just need to recut the holes to attach it now. Will probably do that with a drill tomorrow.
