This year, I've tried to glue various items (back) together. The latest is a cracked toilet seat cover. It's plastic. The break is clean and fits perfectly.
I follow the instructions to the letter.....and all I ever end up with is a gooey gap that never wants to stick. But it certainly WILL stick to my skin should I get any on my finger tips.
I just tried - again - to glue an item together....and - again - have ended up with a gluey thing in two pieces that clearly never ever intends to stick.
Are the instructions wrong? It never works.
