Laminate them only protect it from moisture, but it will distroy your image & the print (jell) coating.
There are ways to achive your B&W prints.
* Resoak your Resin Coated paper in water then refix it then wash it througly for 2X the required time to make sure you remove all excessive silver. You could also try to tone it with Sepia Toner...a more stable iron base toner that replaces the silver in your print, but you have to reprint the prints will a slightly lower contrast, because Sepia slightly increase contrast (about 1/2~2/3 grade). Also Sepia turn your print to a beautiful rich print if you know what you are doing.
* You should try printing on Rag Papers, because they are design to last longer than RC. Sepia toner compleatly replace all silvers in your paper, and the paper fiber don't break down as quickly as Resin.
Newer Archive RC is suggested to last around 25 years (haven't stand the test of time because newer RC debuted in the mid 90s), while Rag papers using archive process have hell up to the test of time...as long as 80 years, but most will last for 50~55years with out lost of tone definition or contrast. (these are ideal situation that you don't touch them with your greasy/acidic fingers, and uses clean cotton gloves to store them in acid free envelope & in dry dark space)
Wow!
I'm glad to hear that someone still is interested in the art that they took time to develop & print their cherished moment/image...With the machine print, automatic, P&S & digitall these days everyone claim to be a photographer when they have never seen the joy of seeing their image comes alive in the developer bath.
