This stuff is the real deal!!!
This stuff is great!!! Worked perfectly for filling in rotten spot on my exterior door casing until I have time to put a new jamb in!!! Long strand makeup of this classic filler can be aggravating if youâre not used to it but it definitely makes for a better fit for the application I used it for! Strong odor, but it was easy to use, cost effective, and dried and cured in less time than I expectedâ¦definitely recommend and would use again

Perfect for what it is, cost effective fixes
Tough to work with but that’s the nature of the product. This is nothing like regular Bondo. It’s wicked strong. I wouldn’t try to make it nice and flat. If you get it to stick and cover your hole leave it and angle grind it off later, sands super smooth. Wear long sleeves, a glove and mask though when cutting into the dry stuff. Long gloves when it’s wet for sure

Tough to work with, but it works
This is tricky to work with, but it does not set up as fast as I thought it would, so there was some time to get it right. Because it is very hairy, you will NOT get a smooth surface upon application. You will have to use a combination of sanding and filling with regular Bondo to get a truly smooth finish. In my case, I just needed to cover a six-inch hole in my fender (using the Bondo backing mesh), so the car will pass inspection for a few more years. I sanded it *reasonably* smooth and called it a day. After painting with whatever Rustoleum I had on hand, it looked “good enough”. Now that it’s done, the whole job feels solid and secure. Very happy.

This is what I call the big guns.
This stuff is tough and is used where body putty doesn’t quite get it done without cracking. I used this on my Vette with great success .

Dries super quick
There are no directions on how to mix or use on the can. I watched the video that comes with the product on Amazon. Not precise at all, kind of guessed based on the video. The video is using the red hardener and not the blue like mine. After I mixed it, about 40 seconds, I started applying to the holes on my transom and it went on, but not easy to apply bc the strands keep it from applying smoothly. It dried in less than a minute as I was applying it. It dried real real quick!! I still had alot left on my applicator that became useless. Keep that in mind when applying, maybe use a small amount to only cover 2-3 small holes, then mix a small amount again so you don’t waste any. Maybe I applied to much hardener and that’s why it dried so quickly?? I tried to use the same amount in the video. Sucks that there are not more clear direction on how to use and mix. I should of went on Youtube and watched a video there. Not sure if I would recommend. I will update this after I sand it off and see how well that goes.
