I just went through this whole process and discovered a couple of basic facts of life concerning RIB repair.
1.) There is no ''quick and easy'' way.
2.) Get the boat out of the water and prepare for a serious repair.
3.) Get the CORRECT repair supplies, including new, fresh adhesive.
4.) Don''t avoid the $40 adhesive because of cost - it works best.
5.) Download the instructions found on
line and follow them religiously.
I used a thick mixture of Dawn and water and slowly went around the boat applying it and finally found the tiny leak. (It was taking my boat a week to go soft and no amount of Viagra helped)
I took other peoples (around the marina) well-meaning advise and the leak re-appeared every two weeks. I was also occasionally dealing with a sometimes leaky fill valve.
Frustrated, I finally got the right materials and waited for the right (temp/humidity) day, did the repair, and it has been rock solid for three months now.
No short cuts. Research on
line for your exact material (my boat is a Hypalon Avon) and get the right stuff and the right directions. Use Toluene for cleaning the surface instead of MEK. It smokes your liver a tad but does a better job. Hold your breath while using it.
