I need to waterproof my canvas on the pu. Can anyone tell me where I can purchase the waterproofing and what is the best way to do it? Is there a special type to buy for pu? Also the caulking on the roof needs to be done. Is there a special caulking to use or will any kind work? Any information would be greatly appreciated. How much of each do you need? I know it depends on the size of the pu. I have a 92 Jayco-14ft box. Thank you! :)
If you contact Jayco they will tell you the proper product to use on the tenting and the type of caulk to use on the roof.:)
I was in Camp World on Monday with a similar question about caulking. They directed me to a self leveling caulking for roof repair. It's a bit thin and will run to all the voids where a traditional thicker caulk will not. If I remember right it had something like hypalion in it, the local RV store had a similar caulking with the same ingredient, but a different brand. They both told me it's the stuff to use for roof sealing around the vent, seems and edges, or on patches.
Good luck.
