I don't bother with extra wax on the foundation, as long as it is waxed already.Paint additional wax onto the plastic foundations. Paint the equipment.
Basically, don't paint any surface that the bees will touch, but paint everything else!Make sure you only paint the outside of the hive, with a good exterior latex.
Not too bad if you allow ample drying time (weeks). The boxes are going to stick together from propolis anyway.(jury's open on the mating surfaces between boxes. Paint on those can cause the boxes to stick together, but it also prevents wood breakdown from moisture)
I did get 2 full suits, 2 smokers, 3 queen excluders, 2 hive tools, 2 bee brushes, solid bases for each hive, a random ventilated base and additional frames and plastic foundations.I purchased supplies for (3) hives in August only to find out I wouldn't be able to get bees until the end of March. I received (2) packages of bees about two weeks ago. Granted mine was in storage for months rather than years, but I have been able to start off with out any issue.
You didn't mention having a queen excluder you might want that once you're ready to put the honey supers on top.
Also I ordered an oxalic vaporizer this week. I wish I had it right now to treat. Hopefully I get it in next week to treat before they start capping brood.
I'm assuming you've got a smoker and veil and hive tool.
Paint them - wait for as long as possible after the paint has dried, then rub beeswax over the mating surfaces. It helps quite a bit.(jury's open on the mating surfaces between boxes. Paint on those can cause the boxes to stick together, but it also prevents wood breakdown from moisture)
