Hi all,

I've been having problems with paint not adhering well to a mayo aluminium barrel. Likely due to how polished it was, the surface had very little key to it, even a light spray of car primer didn't help.

However, I solved this fairly simply by letting the barrel soak in a glass of white vinegar overnight, which keyed it enough for the paint to stick well without risking too many scratches by filing/sanding

Vinegar ...good tip...I would have went with soap and a scotch green scuff pad
