So what'sthe difference between the gel and the spray? I'm just having a look on Amazon and they both seem to be waterproofers? Is one better than the other? I've got the Joni which I believe is Hampstead? I know there's a Napa version but I don't think mine is a Napa. I'm looking at these at the moment http://www.amazon.co.uk/Collonil-Leather-Gel-recommended-Mulberry/dp/B003XNB14K/ref=sr_1_1?ie=UTF8&qid=1343047317&sr=8-1 http://www.amazon.co.uk/Collonil-Waterstop-heavy-leather-waterproofing/dp/B001O5O4L6/ref=sr_1_2?ie=UTF8&qid=1343047317&sr=8-2 http://www.amazon.co.uk/Collonil-Clean-Care-foam-materials/dp/B0040YTK44/ref=sr_1_7?ie=UTF8&qid=1343047317&sr=8-7 http://www.amazon.co.uk/Collonil-Light-Brown-Cream-Polish/dp/B0065KBLWU/ref=sr_1_8?ie=UTF8&qid=1343047317&sr=8-8 http://www.amazon.co.uk/Collonil-PREMIUM-Microfine-leather-polishing/dp/B0049GAYP2/ref=sr_1_9?ie=UTF8&qid=1343047317&sr=8-9 http://www.amazon.co.uk/Collonil-Waterstop-cream-75ml-Medium/dp/B003XVI5ZK/ref=sr_1_21?ie=UTF8&qid=1343047513&sr=8-21 Any suggestions on which is best?
