Managed to get some a few hours worth of work on the weekend.
First had to spray the decal residue with some IPA
The next 3 hours were spent on hand sanding/feathering on all the areas that had flaking.
Gave it a good clean with wax and grease remover before putting on the first coat of primer!
Can already see the massive difference in this area
And of course… I ran out of primer as I was getting to this side.. *facepalm*
