JG - Hi John,
I've used different brushes for each paint layer and both cleaned them in thinners and used brand new ones.
( To check if the cleaning process was the problem. )
I think is probably a combination of the outside temperature and its impact on paint thickness .
As yesterday the driveway was hotter than the tent and the problems are on the body shell.
Whereas, the other day the tent was hotter than the drive and the problems were on the bonnet.
So I will try one last time to fix and repaint the body shell in the shade / low heat.
Or I will adopting a 'survivor' look to get me back on the road.
Cheers, Paul.
