Here are the photos.

Started stripping back with the belt sander but the paint just clumped up and clogged the belt paper (60 grit) so I stopped and moved over to the hot air gun. The white is some more primer/filer I used to try and build up the areas that had bubbled and sanded back to wood. You can see how the soft paint has amassed on the surface:



This was the other side after laying it down on the towel to sand the rear. You can see the pattern the towel made as the finish was just so soft. Even though it had generally sanded down very well and was flat and felt quite hard. The base colour had been drying for over two weeks, before I sprayed more on top, and that had then been drying almost two weeks I think my problem may have been using thinners with a retarder in and thinning down too much, and so getting too much retarder in there:



Body stripped back to wood, with no trace of the original factory sealer coat:



A very thinned (no retarder) first light coat of blue to get the finish into the wood:



I've just sanded this back flat after leaving it to dry for a couple of days and dealt with any deeper sanding marks this highlighted. I will do another thinned coat later today once it's cooled down a bit as it's 30°C outside ATM.
