Thanks for the tip Joe;
I went and got a bottle at Canadian Tire, tried a section on the trailer and ended up doing the whole thing.
IT IS GREAT! No rubbing, no buffing and it shines like never before.
The secret seems to be to throughly soak a small rag and apply it liberaly.
One small spreay bottle did the 16' trailer, 4 Aidorondack plastic chairs and
a 42' patio table. It really brought the table and chairs back to respectability.
I will use this again.
