When I rebuilt my fridge box my research
came down to two options, epoxy
or Awlgrip. There is another commercial
product mentioned by a member
that is designed for painting the inside of water tanks
and such but I never found a source for it in small lots.
I picked the two options based on safety
and smell. Although paint manufacturers won't recommend either due to legal
issues and fear of lawsuits both of these coatings chemically react when they cure and should not leach into food
. Of course I will keep food items in containers as well but don't think toxicity is a concern.
I decided on epoxy
mainly because it was a lot less complicated and more forgiving to apply. It has cured well and I have no odor
at all in my fridge.
