Otter Wax Heavy-Duty Fabric Wax Bar | 3-Pack | 5 oz | Water Repellent Surface Sealing Canvas Wax for Waxed Canvas Jackets, Bags & Shoes | All-Natural & PFAS-Free Beeswax Protectant Made in USA

I did a large canvas jacket. Took a few hours of rubbing it in and then heat gun to cure. Works very well.

I got my duster maybe 30 years ago. I've used the heck out of it, and hadn't really realized that it had lost its water resistance, until I ended up in a downpour (Living in Sonoma County, we don't really get weather, but this was like a Texas downpour). Since I hadn't recoated my duster since I got it, I got these. Well, first I got a single one of the smaller size. That size will NOT do a 30 year old duster, but one block of this size will. Follow the instructions, keep it all warm at a good working temperature, and use one of their wooden sticks to work it in. Don't over do it. It'll still work, and it can still look ok, but it will off-gas something fierce. If, however, you realized that you over did it (I really overdid it), leaving it in a hot place, hanging up on a good wooden hanger, and it'll lose most of that smell fairly quickly. I also did my old canvas "Aussie" hat.... crunchy, but water resistant... I'll be using one of the other blocks to recoat my old canvas tarp that I use for camping, and I don't see any issues (well, I wouldn't get it too close to a fire, but that's a basic intelligence test anyway).

I use it for rewax my outdoor pant, so far so good.

I applied this to a canvas peacoat. It went on easy and I used a hair dryer on high along the way to get it to soak in. Once I was finished, I let the coat "cure" for a few days. It still smelled and had a semi oily feel. Once I hit it with a proper heatgun, that smell and feel went away. With high heat, you can see the wax liquefy and the fabric soaks it right up. It did make my coat a tad darker, but it improved the wind and waterproofness as well.

Takes more wax than expected but it's worth it. Wears like iron. Order extra!

I used this on a Duluth flannel lined firehose shirt-jac. I thought it was kind of useless when I melted it with the hairdryer because it stated white and tacky. Well I got a HEAT GUN and really got it hot so it absorbed deep into the fabric. Basically no longer smells or is waxy to the touch. Just feels like regular Canvas but water beads right off. Pretty cool. Needed 2 and a half bars for a job done right on a 3xl

In my opinion this is a really good product. Make sure you get enough to do the job. May take more wax than you would expect. I would recommend this to anyone who don't mind working a little bit to achieve something really durable.

Otterwax 3 pack... Does the dirty job of waterproofing CANVAS but pretty shoddy job of sticking to much else. I bought the pack because I had a large carhartt coat that I was waterproofing (which for future reference takes about a bar and a half to do, and about a half of a bar for touch up work after the initial curing time) and on a whim decided to use the remainder bar for waterproofing a flannel work shirt. Flannel (and denim for that matter) does not take the wax well, becoming a sort of matted mess and caused some of the colors in the flannel to run. I gave it some time to cure and it "hardened" on me so I'm not quite sure about its usefullness on other materials. On the flip side, the waxing of the coat went really well, needing only some touch up on the hood after the curing period. I have to emphasize that this curing time is necessary; both in regards to long lasting waterproofing effect as well as maintaining the 'waxed canvas' look.

I used these to wax a canvas jacket. 1 bar was not enough and 3 is too much. I wish that they sold a 2 pack. However, I guess that I probably will use it sometime in the future as I reapply wax. The reason that I chose this is because it seems to be the only water repellent wax that doesn't have any silicone, paraffin or any other petroleum based synthitics. It worked quite well, I used an iron and a heat gun to distribute and melt the wax. I do enjoy the smell of the wax and it works great at waterproofing jackets/coats. It worked really well for one sided waxing to create a seal on top of my jacket. The other side of the jacket was completely fine so you don't have to worry about your skin/clothes being in direct contact with the waxed fabric. Even after heating and melting the wax, it was completely fine. I cured my jacket for about 48hrs after and wore it after that. I think its best to do a light coat first and add more as you go.
