What can be, however, is choosing the right sealant for your campervan’s construction, budget, and skill level (if you’re doing it yourself) because every product is a bit different. If you’re struggling to find the right product for your specific needs, this is a must-read post. To roughly sum up everything we’ve covered above, here’s a table comparing the various sealants for caravan awning rail. Product name

Nobody wants to buy a product that isn’t easy to use, and caravan sealant is no different. You should avoid buying a sealant that takes too much difficulty and time to install correctly because this can be extremely frustrating, especially if you’re using it on an awkward surface such as the roof. I suggest you go to a shop that sells fish tanks and equipment for aquariums. Buy a medium sized air pump and about four feet of plastic tubing that attaches to the pump. The pump will be mains electricity operated. Push the other end of the plastic tube through one of the bung holes and down inside the window space. Switch on and air will be blown through the void and out of the other bung hole. After a few hours it will slowly dry out. Best done on a hot sunny day. I also bought a small hygrometer (not hydrometer) from a hardware shop (cost 3 pounds) which measures air moisture. You can use the air pump when the air is at it's driest.That would be its excellent UV resistance and the fact it retains its flexibility throughout its service life, allowing movement in whichever part of your caravan you’re looking to seal. The Hodgsons Seamseal CV is an easy to use caravan sealant that leaves an excellent finish and is ideal for resealing a range of joints. It also offers excellent value for the money when you compare the price per 100 ml.
