I am getting ready to join cup and hull on my 16' BL. I found these on amazon
http://www.amazon.com/gp/product/B00137PWXY/ref=ord_cart_shr?ie=UTF8&m=ATVPDKIKX0DER
made out per spec with Aluminum 5052.
Aluminum 5052
"5052 is one of the higher strength non-heat-treatable alloys. It has a high fatigue strength and is a good choice for structures subjected to excessive vibration. The alloy has excellent corrosion resistance, particularly in marine atmospheres. The formability of the grade is excellent and in the annealed condition it offers higher strengths than 1100 or 3003 grades."
So based on this it looks like a good choice.
Now, I've never used rivets and I read somewhere that if the blind side on the soft material (fiberglass) one should use washer also. Any ideas?
