My dad was a professional painter & decorator. Old School. High standards.
I worked for him as an apprentice for 3 months until he sacked me for being a useless twat.
I still feel ashamed whenever I use a 2 quid B&Q roller (and 5 brushes for a quid) to do a room.
Still, I wouldn't stoop as low as an IcantPaintPod thingy.
He would say : 'Don't be a twat, it will never work' He's been dead a few years but he is evidently still right.
