I wouldn't want to apply epoxy to the inside of the track. Is there an oil type finish that would protect the inside?
What I use on wheelbarrow handles, garden tool handles, and parts of a boat that I don't want to have epoxy on is either linseed oil and turpentine 50/50 (if I think I might want to glue or paint it someday), or linseed oil and turpentine, 50/50, with a brick or two of paraffin per total gallon if I don't think it will ever need glue.
You have to to heat up the turpentine and linseed oil to get the paraffin dissolved into it. You use a double boiler arrangement, (the paint can sitting in a larger pan of boiling water),
outdoors, sober, with a fire extinguisher nearby and kids and dogs not nearby. Works pretty well for wood that will get wet.
It's just the wax that demands heat. If you skip the wax, then just put the linseed and turpentine into a paint can and stir. They mix right up.
Undoubtedly there are easier ways to go, but that's what I do.

A couple of notes;
-You can paint on top of linseed oil once it has cured. It does not stay oily. It does take a while to cure.
-If you want the wax, you find a grocery store with canning supplies, and you will see a 1 lb package of paraffin, usually "Gulfwax". It will have four 1/4lb slabs inside the box, those slabs were what I was calling a "brick".
