I have 2 small chest freezers. I would like to make counter tops on them with either a lamanent directly glued to the lid or by making a top with plywood and lamanent to set on them. so I can have more counterspace to work on. My delima is that the instructions that came with the freezers states "Do not store item on top of unit." I realise that it needs air circulation around it and I cannot have it shoved inside a cabinet or have walls or items too close to the sides and back. But the top doesn't get warm and I would have to make it so I could easily get into it so I would keep the counter top cleared and just use it for workspace. Do you think that placing a countertop on it would cause problems with it? I was planning on having a small shelf on the wall above the door swing to store small appliances.
