I've enjoyed your 'Binge Watch' build thread approach.
I learnt a lot from reading about other people's mistakes.
And I'm sure that others learnt a lot from my (many) mistakes.
However, I wouldn't beat yourself up for having a go at painting the car.
I know my paint finish is rubbish, but it is
my rubbish.
Hope all goes well for you in the professional paint shop.
Good luck, Paul.
