Silica gel to fight rust?

After searching a few frame repair sites in the Knowledge Base, and even some chemistry sites, I found little info on what I was looking for which brings me to this unique question.

Can you use silica gel tabs to reduce moisture inside your frame rails to cut down on rust?

Silica gel is the stuff in those little packets that come in your new shoes. They look like little white plastic pebbles and the package says "DO NOT EAT". The reason behind this is silica gel has an amazing feature of attracting H2O molecules. It traps moisture and keeps things nice and dry so your new shoes don't mold.

Well I've heard about POR-15 as a rust-cure, but what if you could prevent the moisture altogether? My question is, after treating mild frame rust with POR-15, would it be harmful to drop a few of these packets in some hard to reach places? I'm just wondering if I could cause any damage by doing this. Your suggestions mean alot to me since this is just still at the brainstorming stages of an actual plan. Thanks.

I always save those little bags of silica to put in firearm cases, camera bags , etc. I like your thinking. There's also
desiccant it's the stuff you put in the paint booth compressor dry as well. Lasts a long time but still needs to be changed every so often. There's a little window on the hold tank that has a litmus paper that turns color when the stuff is wet. If you don't change it water get's in the line again and fisheyes get it the paint again
