I have an almost full bottle of LRP 'Blue Factor' carpet additive, used at one racemeet only before i packed in Touring. The sponge isnt even that dirty on it, showing it's little use.
Normally about £10.99 as new, I will take £8.00 posted
Likewise I also have a bottle of Nosram Asphalt traction additive. Again used sparingly as this only worked at one track. The bottle feels a bit wierd as another additve got spilled on it making the lable wrinkle, but the contents are not contaminated.
Like above due to little use looking for £8.00 posted
I will take £15.00 posted if you buy both !
