scratched plastic

is there a good choice polish for taking scratches out of greenhouse plastic?  I see a bunch listed but looking they are mostly putting hard plastics first in the list and just listing poly at the end of the list.

My suspicion is that polishing is likely to make the plastic thinner.  

I don't know much about plastic greenhouse as we are still using the glass one my grandfather bought circa 1953.  But I have talked witn farmera around who have them.


What type of plastic do you mean? The thick sheets of flexible stuff or the plexiglass glass replacement? I'm pretty sure plexiglass can be polished but i haven't found a way that is safe.

Are the scratches impending the function of the greenhouse? Or is it cosmetic.

Standard thin flexible poly greenhouse plastic.

Mine is worse than normal because of where it is used.  The big shop doors close over it and the inflation fan pushes the plastic out against it.  But wind still causes the plastic to flex and move so I have a bunch of area that has been abraded rubbing on plywood.  And I am fairly sure it costs me heat.
