Before the weather got shitty last night Spencer (my son) helped my vac out the back, pull out the 1 remaining rear seat belt and then I sprayed it down with the pressure washer - sprayed out all the bees nests in the engine plenum, blasted most of the lichen off, and washed up one corner of the pastel white with some Meg's soap. Turns out the upper paint is in decent shape luckily

so a little more cleanup and a buff and it should be good. The front glass seal leaks pretty bad though, so I may end up replacing that sooner than later, and that usually comes with a little bit of body work to fix the rust under the windshield.
Still I'm lucky that's all there is to do. So next is to POR-15 the front floor and get the mat back in there an cleanup the cab so I can get the front seats back in. A little silicone around the seal should help keep the water out.
I still want to get back to the OG (Original German) paint so may try a trick I saw on The Samba to remove a layer of non-OG paint...oven cleaner
Anyway, progress is good.
Edit, good news - I fixed the way that rear engine hatch closes by adjusting and setting the lid catch the correct way in the rollers and now it closes like a dream. I found myself opening and closing it just to enjoy how well it opens and closes and latches (thanks to Jason

)
