Long term solution?  Likely not.

When I was working at a performance shop, many people came in to have
poly bushings installed in various places in their cars.  They were
always back later to have them replaced.   Either with stock, or suck
it up and kept replacing.   Poly does not last in my experience.
Especially where you have a bushing that rotates.   They tend to use a
metal sleeve that is greased and turns against the poly.    The poly
wears very quickly in this application as the sleeve turns against it.
 In stock application the rubber is bonded to the center sleeve.  The
rubber is what allows for the rotational motion.  This is why it is
important to torque these type of bushings at their resting position
and pre-loaded.

Poly will also tear very easily if used under tension.  The only
lasting application of poly I have been happy with is under
compression without any rotational forces.  My Corrado has been
enjoying solid poly engine mounts for 5 years now (and its a bit
rough, but not a daily!)

I wouldn't ever bother with poly control arm bushings.  Buy good
quality OEM replacements.
