one that holds the best but not messy to work with
i have heard of Black Jack before and because someone else has adviced it, it must be good. Perhaps ask your local DIY store just incase.
You need to use Black Jack. It is messy, but that's what you need to seal the roof. Be careful when you work with it, and clean up immediately. Hope this helps.
Blind Nailing Cement is the best choice. It is similar to roof cement, but has been thinned so that you can apply it with a brush. Nearly any asphalt based roof cement has the potential to be very messy, but with some care, you can minimize the mess. Be sure to get a brush designed for applying the blind nailing cement.
