If it aint broke don't try fixin' it !
The fridge worked perfectly but it was as old as the van. It was extremely rusty at the back and the aluminium frame, as with all the aluminium on the van was badly pitted and dull.
We could have removed all the rust with some sort of potion from Bunnings and re sealed it but we didn't want to tempt fate. To buy new, a gas/240v camper fridge can set you back as much as a full size kitchen fridge.
The door seals were still in good condition with only a few small tears. I covered the entire door in foam bleach and left it for an hour then hosed it all off and left it to dry in the sun. The inside just needed a wipe over with spray bleach.
Shane undercoated it with a grey spray primer which promptly bubbled and peeled off. He sanded it back and Take 2 involved using an "Appliance White" 2 in 1 spray which did the trick. A new acrylic insert in the door and bingo - New fridge
