Durability –The durability of a rubber RV roof sealant is the product’s resistance to tearing or deterioration. It means that the sealant should be very elastic regardless of its type. It should be elastic enough at least to stretch out quite a bit then return to its original shape. We also appreciate that it can work well even in hot temperatures. It is a breeze to use, so even first time users won’t have a hard time in applying it on a wide range of surfaces. Once cured, the product is mildew and UV resistant, allowing it to last longer than other products on the market do. Price –It will be subjective as the concept of expensive will vary depending on who you ask. Therefore, you should get the priciest one that you can fit into your budget. With that said, avoid setting a budget so low that you will not have any other choice but to buy the cheapest sealant that you can find. Remember that when it comes to roof sealant, you will always get what you paid for. How Many Types of Roof Sealants for RV Are There
