Question: I have a tote bag that is canvas and leather and wanted to just use one spray.  would this work?  Canvas is a light beige and leather is navy blue.
Document: This is an excellent product. I have a Mulberry Bayswater bag -- expensive and in a fragile light color (&#34;oak&#34;). I sprayed it very thoroughly with Collonil Waterstop spray before ever using it, hoping to protect my investment. One evening at a restaurant, my bag was sitting on the floor next to my chair, and a waitress accidentally dropped a bottle of balsamic vinegar on the floor. The bottle shattered, and a few drops of vinegar splashed onto my bag.
I purchased this from a recommendation from Mulberry. It seems to have done a good job and very easy to apply. Would recommend for your leather products.
Love this waterproof spray, use it on my bags and shoes, no issues with water - either it's a spill or rain, water rolls off. you need to reapply it once in while.
Purchase this with Collonil gel and both did a great job in cleaning my leather bags! Met my expectations since I was looking for a good cleaner that protects my bag as well and this combination did an excellent job!
Love this stuff! I use it on my premium leather handbags. You do need to allow it to dry about 5 days to really get dry and back to normal. The leather feels and looks the same. I have never noticed a color change either. I wouldn't recommend getting caught in a downpour without an umbrella, but if there is a sprinkle or I make a dash to the car, my bags are fine. Water beads and you just wipe off. Also helped with color transfer.
For anyone who cares about their leather, this product is an essential. It literally makes the water drip off my leather shoulder bag. It dries almost instantly, and the smell is non-offensive, non-existent when dried.
This spray was very good and it did the job. It kept my shoes from getting damaged by water and snow, so I appreciated that. The only thing I did not like was the odor and its potency, so I recommend that you spray your shoes outside or in an area that you don't frequent that much since it's just rather unpleasant, and I don't think it's too healthy to breathe that it when it's freshly sprayed. Otherwise, I recommend the product since it's actually quite protective.
Luckily it was protected with Collonil. I used a tiny bit of leather cleanser on a rag and the color transfer from my jeans wiped right off!
I was dismayed, but then relieved when I wiped off the vinegar spots and no stain was left behind.I recommend reapplying periodically.
It is hard to tell whether it really protects my handbags or not. Even though Collonil has a high name, but given the can is very tiny, it seems overpriced.
Answer: yes
