Replacing rusty and discoloured fridge shelves?

Hi - The shelves in our caravan fridge were starting to rust and to discolour the plastic fridge sides with rust marks.  I looked for replacements but three internal shelves were going to cost an arm and a leg.  I had some toughened glass cut to fit, had all the edges 'bevelled' and have slipped some white plastic poster hangers along the front to prevent knocks.

They look fantastic - total cost:

3 Fridge shelves from Leisure Products:  £90 plus postage - same on ebay
3 glass fridge shelves, cut to size  £14.30 inc VAT

Poster hangers - back of the cupboard!

Total saving £75.70
