I'm looking for a glue/adhesive sealant that would be suitable for patching top loading washing machine's rubber seal (there's a 2cm x 4cm hole). I'm mainly interested in finding glue that would be safe to use (non-toxic? food grade? food safe?). I know it's a really tough task and many would recommend just replacing the seal, but it feels wrong to pay over 100$ for it, and I'm curious whether there's a solution for this.
There's a guy on Youtube who fixed his rubber seal with polyurethane that is used for roofing, but I don't know whether it's safe, even though the guy says it's been working for him for years Video.
Any ideas? At the moment I feel it's either silicone, polyurethane, epoxy-resin, or nothing.
Would this come close at all: Sealant on Amazon
