Update: It is all dry in the car. But then it has not rained yet.
Anyway, cleaned up rusted spots, removed loose rust and blisters and primed over. Cleaned out spare wheel compartment and rust treated and primed. Thinking of stone chipping the compartment for the hell of it.
While doing all this decided to clean up as many rust spots and areas that need attention as I could see. Then oooooooooooooooooooh dear.
I found the bolts and fastenings around the lower tail gate's cables had rusted beyond salvage. Could not undo the bolts as soon as I tried the heads stripped. Nasty. Tried cutting a slot in the top and no, will not budge. Tailgate end is fine in that I have removed the bolt.
So I got a bit extreme and cut the bolt head off the car end. Removed the cables and plan to order new ones.
Now how to get the threaded stud that is left in there out?????
Once that is done I will get some gas struts too as they are shot, as in rusted, but strangely still work.
The rest is still drying out. Sound proofing sponge is near dry in the airing cupboard (nobody tell the missus!).
Bolts are worrying. May need to cut a new slot in the top and try again. Or get a new nut welded onto it to spin out.
Hmmm.
