If you have any other ideas I have asked a direct question in other thread.

So metal shelves are nice and cheap but electrical. I did read a similar thread about grounding the shelves and it talks about PVC. I dont want my tubs to sit little crooked if i put strip of pvc on top of racks. I prefer something of tape wise maybe to put under the tape and on top of it so i dont hurt it with sliding tubs. So which tape or what else i can do?

thanks!

This is how I protect my heat tape. Two thin strips of linoleum for the tubs to slide on.
