Phil, sorry to have to tell you this mate, but in order to get rid of those bubles - which eventually lead to paint cracks - is if you scrape off the paint completely from the affected panels.
and I mean COMPLETELY !
That is badly mixed filler, or bad hardener and/or primer paint hardener !
I see these things every day at Mario's paint shop.
Sadly, there is no cure for soft filler. It never dries out or settles. 50 years from now, it will still be soft and will crack any paint you spray on top of it !
Just look at what happened to my Sud ! It was painted black over silver, probably 15 years ago, but the paint was cracked allover the place ! After scraping off some of the cracked paint, I found that there was filler underneath that was as soft as toothpaste.
The good news, is that not all the panels are like that !
Its just the roof - which I just saw in the picture - and the two rear panels which the paint cracked from the beginning.
So Why not just do those 3 panels over again, and dont do a full respray ?
