Yes, I will do that, but I don't want to crack the bottle untill I need to use it.
I have now got it on good authority that a kicker should not be strictly necessary (which I have found with two other odourless brands in the past) and yesterday, when in Squires at Bognor, I had a look at the DeLuxe Rocket Kicker which says on the bottle that it should work with most cyanos.
I have actually found DeLuxe SuperPhatic a good substitute. It does indeed work on different materials as the manufacturers say, provided that one is porous and being both odourless and water cleanup has a lot going for it.
