Quick fixes in finish restoration are usually never fixes for long. I considered sinking my time, effort and money into making my 76 25 look better, in the end I realized the 25 is a nice boat but will always need work. It was fun to learn on and served the purpose to get us sailing. The smartest thing I did was to stop "improving" it and put those $$$ and time toward the right boat.
I found that washing my boat with Star Bright Nonskid deck cleaner was a noticeable improvement and I used it on the hull too. We would always do a wash before taking her out, with the family this usually only took about 15 min since we kept her clean and never let her get too dirty. We did deep cleaning and my daughter put a lot time on the teak work in the spring after winter, but after that monthly washes at the minimum kept her shiny and got plenty of compliments for a 1976 boat.
