Probably over thinking it but what do people use to seal freeze plugs (or welch Plug if you prefer)?
i am looking at loctite 510 as its rated to 200'c, has excellent glycol/water Resistance. it sets rigid.
That should work fine, doing some on-line checking of what people use has quite a variety of sealants and several who use none. I expect if you got 20 replies to this, you could get 20 different products used.
As a 'prentice, many years ago, we mixed up some gunk (can't recall the name, but it was a mix of a yellow powder and glycerine) for this.
Personally, now I use shellac with, where possible, brass plugs or brass plated steel if those weren't available.
Thanks Gord
it seems its a very opinion based topic, i will try shellac with stainless plugs. hopefully that will keep corrosion at bay.
