Just rinse it with fresh water if it is an elastic spear gun. The trigger mechanism should not corrode if you have a serious spear gun as a it should have a stainless steel trigger mechanism. It is worth dismantling it and giving it a serious cleaning every now and then especially if you use it in sandy and dirty sea environments. A Bit of spray will also help the trigger mechanism....avoid greasy things to triggers as they form cementish material around it especially when in contact with sandy particles.
As regarding the elastic bands it is useless to cover with talcum powder (as I also used to do when I was happy with my first couple of spear guns). Latex bands have a life span and when they are almost half way through they start forming micro cracks at their ends which will eventually become larger ones. Avoid prolonged U.V. Light and any other hot objects to latex as it is the worst enemy!

i had a look at the 2000 uses in that wd40 pdf , in the fine print is a disclaimer:

"The uses of WD-40 described on this website were provided to WD-40 Company by end-users of the product, and do not constitute recommendations or suggestions for use of WD-40 by WD-40 Company.

i read wd40 is 25% petroleum, petrol ruins soft plastics. 

unless you have a sticking mechanism i dont think you should spray anything, this also goes for doorlocks,  spraying will just make it sticky and dust and sand will stick to the parts. for door locks you use dry powdered graphite
lubricant (its like pencil lead)

for knives you use silicone grease, i dont have  a spot of rust after years of sea use .

I agree 100% that WD40 has the tendency of hardening the rubber while silicone grease has many good properties especially for rubber. Whenever I dismantle my air speargun I rub all the rubber with silicone grease. It will help for the preservation of the rubber and to serve as a lubricant to moving parts
