Dianna:
You’re already using the traditional method for
this process, but any additional tips needs some further
information from you: What kind of surface is covered with the mastic?
How much ventilation is available? Do you have access to a belt-
sander? How big an area is involved?
Answer these questions either here or e-mail me direct
at “hawts@nosc.mil” and I’ll try to help.
Regards,
Ron Hawtree
