Not a carpenter but Stairs Done

Looks good!
Where do you get that much Fiberglass Resin from!? Sorry,Fiberglass is one area I don’t know how to work😉
Both good ideas,to avoid sliding off! OOBeau...what did you do to give each rung the strength to hold your body weight? Some kind of metal rod under each rung..or what??
I went back & studied the photo better. Good idea👍 Besides adding something to give GRIP..I’d pour a little old motor oil,or something on the legs where they touch the ground(to deter termites)😉. “Treated” wood these days is a far cry from the old stuff & most isn’t even treated “For ground Contact”...🥵 We make up for it by using some other deterrent/preservative.
