This is the best price I have seen in a few years

Would Recommend

This putty knife was used to spread a bonding and sealing compound that is similar to mastic. It has the right flexibility and width for the job and to fit the container that held the compound, plus it also worked with a similar compound that was applied from a caulking gun.
