Waterproof camping and boating gear seems like kind of a no-brainer. Shouldn't ALL camping, and especially boating gear be waterproof? Maybe it should, but not everything you buy is waterproof -- or even water resistant. But that is an oversight you can usually correct.
We usually don't set out to participate in outdoor recreational activities in bad weather, but is all too common for some to strike while we are enjoying the great outdoors. When that happens, it is good to have waterproof or at least water resistant gear.
A lot, but not all, of camping and boating gear and apparel will come from the factory waterproofed. Some fabrics are naturally waterproof or at least water resistant. For those items that do not include factory waterproofing or for items that may have lost some of their waterproof capabilities due to normal wear and tear or abuse, you can often solve the problem with a product like Camp Dry spray. It is not too expensive and is very easy to use. Just spray a coat or two on clean dry items like tents, jackets, gloves, and footware. It is said to work well on tents, tarps, boots, hunting apparel, outdoor gear, boat covers, and more. I have used it for years to waterproof my OHV, cowboy boots, hiking boots, and to improve the waterproofing on coats, tents and awnings. I figure it will be good to use on the main sail cover on my sailboat. I have even heard of people using it on canvas shoes, which could be a real boon to boaters. Be sure to test it on an inconspicuous spot on light colored materials to avoid permanent stains.
The first step in waterproofing your camping or boating gear is to make sure the item is clean and dry. Be sure to brush debris and caked on dirt from the seams of boots and shoes. Remove any stains you can. You will want to set up your tent and make sure it is pulled tight when spraying your tent to ensure complete and even coverage. You may also want to waterproof your packs. Pay special attention to seams on all items: tents, awnings, gloves, boots, shoes, and jackets. Those are often the most likely points of leakage and need the most protection.
Camp Dry normally dries in abut 24 hours and cures completely in about 72 hours so you want to allow some time after applying it before using the items and subjecting them to precipitation. Some forms of waterproofing can seal surfaces too well, causing them to trap moisture inside as well as keeping it out. Camp Dry says it has no effect on the breatheability of fabrics when applied per the manufacturers instructions. Attempting to waterproof items with other kinds of sealant may destroy breatheability and make them uncomfortable to wear. Non-approved chemicals may cause damage to many materials. If possible, test any protective product someplace it won't normally be seen to be sure it is safe to use on the full item.
Items protected with this kind of waterproofing will not stand up to being submerged for any length of time but normally does a good job of protecting them from normal dew, rain, and snow. Camp Dry can even help protect parkas and other snow gear against melting snow. I've seen way too many snow-rated garments that let melting snow in so as soon as you step in out of the cold and the snow melts you start to get soaked! Camp Dry and similar products are designed to waterproof fabrics and footwear and are not designed to waterproof equipment. You can use it to waterproof a canvas or heavy fabric bag to protect your cell phones or radios but don't use it on the devices themselves. If you are looking for something that protects even when submerged, remember you will also need some way to seal the items where they contact your body. Waterproof boots can still get wet inside when submerged because water can soak down between your leg and the boot. Waterproof gloves may allow water to enter through the cuff when submerged. I have seen people use duct tape to seal boots and gloves but it can be painful to remove when it gets stuck to your skin.
I have not had any problems nor heard of any problems with Camp Dry staining or otherwise altering the color of anything I've used it on, but, as always, try to test it on an inconspicuous area before applying to the entire item just to be sure. I have used it on canvas, nylon, leather, and even suede, on jackets, gloves, shoes, and boots, Even on my OHV riding pants! I haven't tried it on riding jerseys. I suspect the open weave that provides adequate breathability wouldn't be easily sealed against rain and I usually rely on a light jacket or poncho for upper body rain protection on the trail.
Applying waterproofing to boots or gloves is NOT a substitute for waterproof boots and gloves. Applying waterproofing can help prevent water from easily penetrating materials but it is no substitute for truly waterproof construction, like rubber boots or rubber gloves.
Another option is to put your stuff in dry bags. Dry bags are often used on boats and can provide excellent water protection for gear in camp. Dry bags are especially useful for things you normally wouldn't apply waterproofing to, such as clothing, socks, and underwear. If you don't have any dry bags you can get some protection by putting your stuff in plastic trash bags and closing them tightly. Of course that only works well for things you have in storage, not things you are wearing or actively using.
Stay dry!
