No, not the missus, that would be too hard, I meant an el-cheapo, 4 year old board bag that 's got a bit of wax on the inside and the zippers don't go down the side very far.
Getting inside with a rag covered in turps is not fun and I still have nightmares about the time I tried to turn a bag inside out by hand, around 5 years ago, i was rooted by the time I finished.
So this time I put a hole in the front of the bag using a soldering iron so that it sealed the hole at the same time, then I threaded a rope through the hole, found a stick, drilled a hole in it ( I used a flat piece of fiberglass sail baton that I happened to have) threaded the rope through the stick and tied a knot in the rope.
then I took it out the back, tied the other end of the rope to the fence, and started pulling the open end of the bag over the closed end.
In a flash it was inside out.
Gave it a wash with turps and a rinse with hot soapy water.
Took the stick off the rope on the inside and put it back on the rope on the outside of the bag, did the opposite and the bag was bag to normal in no time.
I'm not going to say it was a breeze, you still need a bit of elbow grease, and you must be careful not to damage the zippers, but it was no where near as hard as doing it without the rope.
And I didn't get gassed by the fumes.
