When my daughter was very young we carried ice cream bars in the rectangular evaporator plate compartment near the top outboard
side of the fridge. Unfortunately, sometimes the bottom layer would freeze to the surface of the plates, making extracting a bar problematic. Unfortunately, she--then 7 or 8--decided the use a steak knife to "chisel" a bar she wanted free. She did get her ice cream bar but also managed to punch a small hole in the evaporator plate.
As a temporary measure (that subsequently lasted another 8-9 years) I cleaned the--by then room temperature--evaporator up, lightly sanded the area over and around the obvious hole with fine sand-paper and used a portable 12v shop vac to remove the sanding
debris, wiped the area clean with 90% alcohol from our medical
cabinet and when it was dry, applied some epoxy
resin (the material that comes in the West System Patch kits) to the area and over laid the hole with a slightly larger than postage stamp sized piece of fiberglass
cloth from the patch kit, pre-saturated with epoxy
. Once that all kicked off and became quite hard, I sanded the surface smooth with fine sand paper and used a little white "Enamel Repair" paint
to cover it with. Our refrigeration
tech came by the boat
to recharge the system and expressed skepticism with the repair but it held, and continued to hold for another 8-9 years, until the compressor
in our, then 19 year old, unit gave up the ghost and we replaced the whole system.
