Review: Superb wood filler - Rather than replacing more than a dozen rotted deck boards. I decided to try to fill the "ravines." I tried many wood putties: n'yet . Bondo? n'yet (Became unworkable too fast for my application). This kit with its slow hardening was perfect. Beyond being simple to use, with the two attached pumps pre-measuring the correct amounts of the resin and hardener. I decided to WILDLY experiment with "additives." First, I added a couple of scoops of Durham's Water Bingo! Mixed easily and perfectly increased the amount of the glop and was easy to spread into the ravines. Dried hard as a rock but it must be abraded hard for painting. Next, I stuffed steel wool into craters, which are deeper than ravines. Then I infused the steel wool with the mixed epoxy. Why? Epoxy bonds with steel and throws off heat to boot. The gaps I filled with steel wool and epoxy are clearly stronger than the original wood fibers because solid steel....Btw: you can perform microsurgery on the "treated" steel wool if you have a competent grinder with attachments. Finally, I mixed grout with sand into the epoxy. Why? Because the sand in this concoction, when used to fill shallower gaps, provided a surface onto which coating would better adhere. Success. Moral of the story: I would have been far, far better off, prying up the deck boards, purchasing new ones, and installing them. Why didn't I do it? I am a retired desk jockey and when I started the project more than a year ago, I did not have the carpentry skills to cut and replace the boards. I have them now. Absolutely no regrets even though the filled-in boards are less than cosmetically perfect. Two warnings: you should absolutely not experiments with epoxy additives. Use only those that the manufacturer prescribes. My outcomes were fine but yours may be disastrous. Second, I could care less about bubbles in the epoxy. Accordingly, my recommendations are expressly limited to the use to which I put the product. Review: Great value & excellent utility - I use a epoxy for a lot of different reasons & have tried several different brands. I'm an avid maker/DIY type (not professional) One of my favorites is West Systems yet its very high in price in comparison. I bring up West because its the closest competitor that I can think of for boat construction aka working with fibers. With Totalboat you get a lot for your money, almost at 1/4 the cost. I have not conducted any destructive or chemical test. I will say it feels nearly the same. The cure time for both SLOW hardeners is about the same. I'm a bit more keen on Totalboat's plastic containers because its easy to set up. With the other I need to dangerously pry off the metal lid. Another perk with this product that it comes with helpful accessories including 2 mixing cups, gloves, mixing sticks, & a plastic spreader; I know that's minor, but wow its helpful. I don't know how Totalboat does it. While I got this on sale, even their regular price is better. ## Features - Choose Fast Or Slow Hardener: Pot Life Ranges From 12 Minutes @ 75F For Fast Hardener, To 20 Minutes @ 75F For Slow Hardener ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00HR8515C | | Best Sellers Rank | #62,917 in Sporting Goods ( See Top 100 in Sporting Goods ) #95 in Boat Maintenance Supplies | | Brand | TotalBoat | | Brand Name | TotalBoat | | Color | Clear | | Colour | Clear | | Compatible Material | Fibreglass | | Container Type | Bottle | | Customer Reviews | 4.6 out of 5 stars 878 Reviews | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00811932021021 | | Item Form | Liquid | | Item Package Quantity | 1 | | Item form | Liquid | | Manufacturer | TotalBoat | | Material | Epoxy Resin | | Material Type | Epoxy Resin | | Model | TB-521KITSB-K | | Other Special Features of the Product | Slow Curing | | Part Number | TB-521KITSB-K | | Special features | Slow Curing | | Specific Uses For Product | Fiberglass repair | | Specific uses for product | Fiberglass repair | | UPC | 811932021021 | | Unit Count | 1 Count | | Viscosity Level | Low | | Volume | 739 Milliliters | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** TotalBoat - **Item form:** Liquid - **Material:** Epoxy Resin - **Special features:** Slow Curing - **Specific uses for product:** Fiberglass repair ## Images ![5:1 Epoxy Kit (Gallon, Slow Hardener) - Image 1](https://m.media-amazon.com/images/I/71n+1sfhqUL.jpg) ## Questions & Answers **Q: Is this a no blush epoxy?** A: Unknown **Q: Is this polyester resin** A: No it is not polyester resin. It is epoxy with a 5 to 1 ratio, and cures extremely hard. Polyester should not be used on a repair below the water line. Epoxy will not allow water to absorb into the repaired area. **Q: can I use this to fix lamination on my RV side walls** A: Worked great for me rebuilding the wall sandwich (fiberglass, thin ply, foam board,,,) after water delamination. **Q: Can you do inside of bathtub with this?** A: Good Afternoon, this product cures to a high strength, water resistant finish, so using within a bathtub should be fine. Thank you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb wood filler *by R***N on 17 October 2021* Rather than replacing more than a dozen rotted deck boards. I decided to try to fill the "ravines."
