EDIT -Update
Just browsing through some of my older reviews and found I have been remiss in not updating the excellent follow up service I had from Autoglym after my previous review.
Had a telephone conversation and subsequently received a replacement part free of charge even though warranty had expired and some complimentary product to replace what had been wasted.
Apologies Autoglym, I was quick to complain and should have responded sooner to your excellent treatment.

I would love to give a long term review but after less than 2 years it’s virtually useless. The blue cap with the nozzle that attaches to the plastic bottle is impossible to tighten securely. It constantly falls off with the slightest of movement and I’ve probably wasted more money in spilt cleaning foam, wash and seal than this cost me in the first place. I would advise against buying and look for a better quality product.
