5200 is not a replacement for epoxy, and IMHO shouldn't even be used on a boat. 5200 has too strong an adhesion strength for anything that may need to be removed at some point in the future, and you should probably be using 4200 instead.
Epoxy is really a structural material, and should be used to do things like attach stringers to the hull, fill small voids or holes, etc. However, epoxy has one major caveat to it. It must be painted or coated to protect it from UV degradation. Epoxy breaks down under UV...
looks like MAS is a little more pricey, but it you don't have to buy thickener for West... so when would i use epoxy as an adhesive, rather than 5200? Any pros, cons?

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
