So i've been looking around everywhere, and these thermal fuses seem to be pretty hard to come by in my region. Pretty much everyone I've called locally only sells fuses for 10A, nowhere near the 2-3A i need.
The closest I've found
is a radial one, but I'm not quite sure if the 'body' is metal as advised against, i think it's plastic but i can't be sure?:

So would i just use something like insulating tape? I've never done something like sleeving a wire, so I have no idea if there's a more common method that i just have no knowledge of.
I did find an insulated fuse on another site for the entire continent, but for some reason its 20x the price, so I'd prefer to go the cheaper route if i have to buy more than one just so i don't break the bank if i ruin a fuse or two trying to solder it back in.
As for the silicon sealant, that's another headache. I know the purpose is for placing the fuse inside the inductor, but I'm not sure if it's supposed to transfer heat or avoid it, or be conductive vs. non-conductive, so there's one or two options but I'm not sure which one is the most appropriate:
