Antifreeze seeping through heater hoses?

[71 SE3834V]

My car has been in storage since mid November. All was good when it was put away.
Went over to take a couple of pics today for someone and looked around the engine bay. Noticed 3 out of 4 heater hoses were shiny and sticky. What the hell! These are Gates Premium 5/8" hoses that were replaced in 7/2013 with new Prestone antifreeze. Engine was rebuilt last fall and new antifreeze was installed once again at that time.
Strange the 1/2" hose that runs to the valve is dry as a bone. It's not a Gates but says "Standard Heater Hose" on it and it was one that I've had in a box for who knows how long. Neither of the new Gates radiator hoses I installed at the same time are showing any problems.
What the heck is going on? The nasty 40 yr old hoses I pulled off weren't doing this.

Hi Jeff,

I just went and looked at the Gates heater hoses I put on my 383 last spring. I don't see any signs of what you are seeing with yours. The antifreeze I'm using is NAPA extended life plain old green antifreeze.

Could be a little oil spitting off your Valve cover vent.

Nope. No oil anywhere. Oil don't smell like this did. Engine hasn't run since Nov. and hoses were dry at that time. When looking at the hoses the shiny/stickiness ends where the hoses end. No signs of leaking at the connections. No dripping, just shiny/sticky hoses which goes all the way to the water pump housing and like I said, just the Gate 5/8" hose not the Standard brand 1/2" hose.

Ok, looking at receipts I was slightly mistaken on the info. I installed Prestone when I replaced hoses during a timing chain replacement in 2013. Last fall the engine was rebuilt, re-cored radiator, etc. and I installed Peak Long Life antifreeze.
Shouldn't matter. Hoses are suppose to keep in the fluid. I'm so tired of having to replace faulty new parts.

Just found out about it yesterday. I was planning on driving the car up to the store to show them as soon as it comes out of storage but that will probably be a few weeks yet. Gotta get a master cylinder installed before it can be driven.  Tried 2 new ones during the engine bay renovations last fall but both would leak from the cap/cover. Ugh! Need to try a different brand so I left it off all winter. Too cold to deal with it.

Just A thought. I disconnected, both a/c and heater hoses.  I never drive them in hot/cold temps outside.

The heater hoses on the superbird did this after sitting all winter... I had antifreeze all over the floor. All hoses were new in 2005.

Considering the day I stored the car last fall was in November and snow flurries were flying I don't think that's an option.
