[Paddlewise] Adhesives for polyethylene

Hi,

as a frequent Sikaflex user, some notes:

There are different formulations available here:

Sikaflex 221 is proposed to be a multi-purpose sealant

Sikaflex 291is mentioned as a marine sealant and adhesive, and prooved 
to give stronger bonds then 221. It is the preferred adhesive to glue 
skegs (mostly mahogany ) on fiberglass kayak hulls, but I think it does 
not stick well on polyethylene. I had no great success with 
polycarbonate either. Please correct me if you have other results.

Special formulations (also UV stable) are used for gap filling of teak  
sailboat-decks.

When applying Sikaflex, work with surgical care, as you will easily 
spoil anything, especially when you use the black stuff. Smoothing of 
the surface can be done by using dish-washing detergent  in water, which 
allows for touching the surface without sticking to it.
