So I've heard of a few people using a mixture of I think boiled linseed oil and something else has anyone used or heard of this process to help soften up intake boots?
I just let mine boil slowly for an hour or so to get 'em warm enough to soften up a bit. Nothing but water in the pot. Worked out fine. Otherwise I think wintergreen is what is used to boil rubber parts in. Someone else might verify this..
