PIPUK,
The only Motor Factor we have near to where where I live is Halfords and I suspect that if I go there and ask for TFR, they will look at me with that vacant look on their faces and just like me will say, "what is TFR" or "sorry mate, we don't sell that." Would this "Snow Foam" do the job please??
Best wishes,
RonBin
Snowfoam would do the job. However, I would look a bit harder for motor factors. There are probably 10x more motor factors in my local area of the UK than there are Halfords stores. It would really surprise me if there are not a number of suitable stores in your area.
