Eternabond tape question
I want to seal my front & rear seams on my new toy hauler. I was wondering if the eternabond tape is good for this. I was was wondering what width should I use, I was thinking of 6 Inch. I also want to seal all the vents and sunroof etc. thinking of 4 inch for this. Anyway, I have seen all types of this tape, fabric backed, white backed, etc. Which one should I buy and where should I buy it from? Any help and info on installation would be greatly appreciated.
