Thanks for all the reply's chaps.
I have found when a builder has removed the odd sticker, by the time we get around to clean the ones that have been removed they are a lot easier to clean, perhaps the sun dries out the glue.
Paul Griffin. What is tfr, is it traffic film remover, and where can it be purchased.
Still thinking of buying wfp, have a vehicle so might look for a second hand system, it would have to fit into a Fiat Doblo.
Can anyone recomend a system, or have something for sale.
Thanks Andrew.
