Is there a formula for figuring out how much fiber to use on each seal. I know that each seal comes with specs on what is needed for that particular size. But I have a mixture of 4", 3", 2", 1 1/2", 1", and 3/4 and need to order fiber and chico. All the seals are eyx's or the next size up. I have never had to fill this many seals before and I've come up short on fiber before.
Second is it ok to use Duct seal to pack the larger seals?
