I applied it twice at an interval of 12 hours before applying a second coat. I’ve been out in the rain and the water slid off my bag. Great product! I would use it again and I have enough to re-coat my bag in 6 months time. If it’s good for canvas on boats, then it’s going to be good for handbags too right !? Review: Easy to apply, great water protection - Very easy to apply with 4 inch brush, enjoyable task as the fluid seeps into the car top. Dried quickly in the shade with great results - when it poured down the beads were very satisfying. My Saab 9/3 took approx 0.8 litres so its not cheap but neither is a new top. Ill be using every winter from now on. ## Features - WHAT DOES THIS PRODUCT DO - Specially formulated to seal and protect your canvas soft top this polymer based sealant will provide protection against moisture and other environmental damage. Used after Protex Canvas Cleaner or Canvas Dye this is the final stage in the Protex soft top restoration process. - COVERAGE & PREPARATION - It is recommended that approximately 500ml of product is sufficient to waterproof a top for a 2 seater car. It is best to apply the product in cool/overcast conditions so that drying time is not too fast and to avoid causing an uneven finish. - APPLICATION STEP 1 - Shake the bottle well and decant sufficient product into a separate container to apply to the soft top. Starting in the middle and working towards the edges, apply the waterproofer with a clean paintbrush. Avoid spilling any onto the vehicle's paintwork. - APPLICATION STEP 2 - Leave for 3 hours to allow the waterproofer to dry and if required recoat again allowing 3 hours drying time. - FOLLOW UP - It is recommended that the canvas is sealed and protected using Protex Canvas Waterproofer every six months. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0075IV3OC | | Best Sellers Rank | 18,545 in Automotive ( See Top 100 in Automotive ) 600 in Motorhome Parts & Accessories | | Brand | PROTEX | | Colour | Clear | | Compatible Material | Canvas | | Customer Reviews | 4.4 out of 5 stars 551 Reviews | | Item Form | Liquid | | Item Weight | 0.53 Kilograms | | Item form | Liquid | | Item weight | 0.53 Kilograms | | Manufacturer | AutoUseful Ltd. | | Manufacturer Part Number | ST22 | | Material | Silicone | | Model Number | ST22 | | Number of Items | 1 | | Style | silicone | | Style Name | silicone | | Surface Recommendation | Fabric | | UPC | 608819984766 | | Unit Count | 500.0 millilitre | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** PROTEX - **Item weight:** 0.53 Kilograms - **Material:** Silicone - **Style:** silicone - **Water resistance level:** Waterproof ## Images ![PROTEX Convertible Soft Top Canvas Waterproofer 500ml - Seals and Protects - Image 1](https://m.media-amazon.com/images/I/71rOxVMww6L.jpg) ![PROTEX Convertible Soft Top Canvas Waterproofer 500ml - Seals and Protects - Image 2](https://m.media-amazon.com/images/I/61fxCujvHhL.jpg) ![PROTEX Convertible Soft Top Canvas Waterproofer 500ml - Seals and Protects - Image 3](https://m.media-amazon.com/images/I/61+vTeZOH4L.jpg) ![PROTEX Convertible Soft Top Canvas Waterproofer 500ml - Seals and Protects - Image 4](https://m.media-amazon.com/images/I/718fFTpLj5L.jpg) ![PROTEX Convertible Soft Top Canvas Waterproofer 500ml - Seals and Protects - Image 5](https://m.media-amazon.com/images/I/81PyinnPI2L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How does the waterproofer look on a tan top? Will it darken it, and will it cover up or magnify appearance of minor scratches?** A: I used it on a camel color canvas top and it works and looks fantastic! Didnt change the color at all and any existing stains werent magnified . **Q: does this product seal thread seams?** A: The trick is to dab and poke the solution into fine details - it’s a water consistency, so tends to easily roll off - you MUST have patience and diligence when applying. Use soft bristle high-quality brush, paint on in real small zones. DO NOT let it get on glass or paint, and dry - IT WON’T COME OFF. To answer your question, yes, it’s a most effective product. Highly recommend masking off glass and paint first, real good, before you start applying. My next time, I think I’ll try a very small foam type paint roller, instead of a brush, and go REAL slow. Good luck. **Q: Can Protex World waterproofer be used on my tan Saab convertible top?** A: I don't see why not. But I did not like this product for many reasons. First, the bottle came not full, the product is very difficult to apply and if you want to have an even coat better be careful because youay need more bottles, specially if bottle came almost half full to start with. After a few days the product starts running off on my windows. To be fair, it seemed to seal the roof but I will try somw other product next time. My car is a BMW 650i convertible, black top... **Q: does it UV protect?** A: Yes it does. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It does the job and I used it to waterproof my canvas bag *by C***N on 5 January 2024* I brushed this on my cavas Troop Bag as it’s not waterproof. I applied it twice at an interval of 12 hours before applying a second coat. I’ve been out in the rain and the water slid off my bag. Great product! I would use it again and I have enough to re-coat my bag in 6 months time. If it’s good for canvas on boats, then it’s going to be good for handbags too right !? ### ⭐⭐⭐⭐ Easy to apply, great water protection *by F***T on 12 September 2025* Very easy to apply with 4 inch brush, enjoyable task as the fluid seeps into the car top. Dried quickly in the shade with great results - when it poured down the beads were very satisfying. My Saab 9/3 took approx 0.8 litres so its not cheap but neither is a new top. Ill be using every winter from now on. ### ⭐⭐⭐⭐⭐ Great product *by T***E on 12 August 2021* Watching rain water bead on the canvas soft top is very satisfying. The Protex product appears to be far superior to other products I've used in the past. The waterproofer is straightforward to apply with a small brush and a cup to hold the product. The second coat is harder to apply than the first because it just wants to bead and run off, so you have to take your time. At least it demonstrates how effective it is. Once dried you'd never know it had been applied - it has no effect on the appearance of the roof. ## Frequently Bought Together - PROTEX World Convertible Soft Top Canvas Waterproofer 500 Milliliter - Seals and Protects - PROTEX World Convertible Soft Top Canvas Restorer (Black) 500 Milliliter - Color Restores Like New - PROTEX Convertible Soft Top Canvas Cleaner 500ml - Deep Cleans --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/60102262-protex-convertible-soft-top-canvas-waterproofer-500ml-seals-and-protects](https://www.desertcart.jp/products/60102262-protex-convertible-soft-top-canvas-waterproofer-500ml-seals-and-protects) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-15*
