thanx for all the info and ideas guys
i ended up going with the good old stinking fish oil and then a coat of tectyl 506 wax type stuff over the top, i also drilled a heap of holes every where and used rubber gromets to fill the holes. they dont look to bad at least i can rest knowing its all protected inside everywhere.and yes those little tube thingy off a wd40 can worked a treat.
now my shed absolutely reaks like shitte ,i might have to stay out of there for a few days
all for a good cause tho
cheers
