How can I make Morrisons flower buckets 'pretty'?

Acerfan

Just wondering if anyone has any tips on making the Morrisons flower buckets (8 for 99p) look a bit 'prettier'. I want to grow some early potatoes in these, but have a feeling my landlord won't be too happy with a load of black buckets in the garden. I've got some car primer spray I got from poundland I was thinking of using under some interior gloss in nice colours, but have a feeling this will just wash off in the rain. Does anyone know if this will work? I only want to paint the outside of the buckets so there shouldn't be a problem with toxins etc getting into the soil.
Also, if I paint the gloss onto wood, do you think that would last?
Many thanks in advance for any tips anyone can give me,

To be honest, I just paint anything with any kind of paint I fancy and it usually turns out ok. The car primer spray sounds ideal and I don't think the gloss would wash off.
I painted some grotty rubbish bins with stone coloured masonry paint with some sand added to it a few years ago. The advice I was given at the time was that masonry paint would never last on plastic, but it's still going strong yet.

Speaking of painting any old thing, I recently bought from the recycle dump, a fibre glass/ or plastic tall coal scuttle, someone had already drilled holes in the base. So once I've painted it and planted it up, it will give hight to my displays
