If you have a clear shot at them, drill them out and go one size over on the rivets, put sealer on and around the rivets, should work well.

Another way you could try is an epoxy sealant. Gluvit is a common one to use.

Unless you got a river gun & the proper rivet set you'll be wasting your time.

Air hammer and rivet set kit wont set you back more than about 60 dollars and you can fix your problem now and any that arise in future.   You could also look at purchasing a few blind fasteners such as sealed riv nuts if the areas are hard to reach both sides of.

I tryed tightening them first so far so good.i filled it with water and no leaks.but How much longer do they last if just tightening them up?

Solid rivets work by swelling the shank in the hole, beating on both ends simply flattens them.

It really depends on how much the rivet was already bucked. 

 

A rivet that is over bucked won't hold any tighter than a rivet that is simply bucked properly. 

In my position I would change them or apply some free flowing sealer like gluvit

That's not the case. 

Solid rivets clamp between the head and the flattened end. if removed properly when changing one the hole will be the exact same as before. 

There are scenarios where the shank is swelling in the hole but in  those case damage is occurring. That damage will be visible on the bucked side of the rivet as well
