I have several Sealant Applicator Guns - all the real cheap types. They
work but, for more viscous products, can be very tiring.

The viscosity of many things tends to reduce as the temperature is raised. So
perhaps making sure that the sealant is not to cold might help. e.g. not stored
in a cold garage during winter.
