Work fabulous couldn't be happier
I received treat as my complimentary liquid and it really is a treat,it's my go to interior spray ,leaves a lovely natural finish with no greasyness or shine ,i cannot recommend this highly enough.
Handy sized 250ml bottle of Guard so I could give it a try. Used it on a friends white VW and a black Skoda. Easy to apply by hand and easily buffed off giving a very good finish to both cars. The Guard on it's own bought out the white paintwork far better than an alternate (not M&K) show wax I had tried previously. Would be happy with this as it's normal price but getting it for free, now that's a bargain :)
