Thanks to Stephen and Matt for the advice. I had a look at the recommended products.

Seems like 3M have two; one in a yellow container and the other in purple. While Farecla have about ten different products.

So guys could you make it simple and tell me which particular product you recommend?

Thanks,
Greg
