The run on the top tin should have been the final colour but it came out lighter, i would sacrifice hardner for more colour if i were to do it again, its just you run out of room in the bottle if you follow their instructions. Thats why it would help spraying on a hot day like i did.
The finish came out well and survived a scratchy greenlane with neil the other month. I think youd have a job damaging it as it is that tough,
Like i said prep is key especially around rivet heads etc, I would remove as much as possible if i were you to get a clean look as overspray around washer jets etc looks terrible. Not forgetting etch priming bare metal too.
I couldnt say on repairing it yet though but id imagine if you used the same ratio of paint to hardener youd be ok ( i used a glass beaker and measured ml’s exactly).
Like i said any more qs fire away and ill do my best to help and if your close to bristol i could let you see before you went ahead
