If your anything like a lot of us with MH's who are always fiddling and enhancing and making additions you probably come across the problem with screws not tightening into wood anymore! I found this especially a problem when in some panels the wood is fairly thin so the usual solution of using matchsticks or cocktail sticks won't really work. Anyway yesterday I had a few loose holes so decided to try another method and can report its worked with VERY good results. It's simply using toilet paper and wood glue. I used 3 sheets of toilet paper and a spoon full of wood glue. The tissue paper dissolves immediately and it leaves a paste. I filled the offending holes, wiped clean and left to set overnight. Just screwed the screws back and it's as strong if not stronger as the wood itself!
