The filter added to a single-coated lens, will not improve flare resistance.
The lens must be considered separately from the filter.
The flare of the lens will remain unchanged with or without the filter.
The flare from the filter will be less (probably) than a single-coated or
un-coated filter, but does not reduce the amount of flare that will arise
from the lens itself.
In fact, the filter will actually increase your flare problems by the amount
attributed to the filter. In other words you will have less flare on a
single coated lens without the filter, than with the multi-coated filter
attached. If you are using the filter to reduce flare, you will not achieve
your goal.

Subject: Multicoated filter on a single-coated lens
Let's say I mount a top-end multicoated (B+W or Pentax) -010 UV filter to a
single-coated lens. How much will the filter improve flare resistance?
The lenses in question are my Vivitar Series 1 13/2.3 and 300/3 telephotos.
