Wish I took photos, I bought a Yakima Skybox 16 for $40, it was a mess. 7 Cracks all over it. They ran it into a low parking garage and had duct tape all over it.I bought this and the fiberglass cloth rather than the kit because you get more, and its a little cheaper. Also the fiberglass cloth I read is way better than the batting you get in the kit.This stuff and the cloth completely sealed all the cracks and I then drove it 1,500 on a ski trip at 80 miles an hour, no issues whatsoever... The place we stayed had an industrial garage door that came down on top of it and protected my car, damaged another part of my Yakima but this stuff held just fine on the original cracks. Will be using it again to make that repair.Mixing and Applying:I mixed it in a cleaned up cottage cheese or sour cream cup. What I did first is figured out how much I wanted to make by reading the label and then filling the cup with water and using a black marker to mark the spot on the outside of the cup to see how much resin I would need to put in. This way I could get the hardener drops correct with the ratio of resin. I think I did 1.5 cups of resin with 50 drops of hardener, this was a month ago, sorry. I know I did like 10 more hardener drops than it told me to the second time I used it because it was weak the first time. I then mixed it with a wood paint stir for 1 min. That may be excessive, but I went way to fast the first time I did it and it seamed that for some parts the hardener did not get dispersed well and took 48 hours to cure. I did it in a garage at ~55 degrees F. I was able to do 8 feet total of cracks, 6 inches wide with the fiberglass cloth with about 1.5 cups of resin in about 10 min and it did not set up that fast. I used up all of the 1.5 cups on this run. 12 hours later it was set almost everywhere, few tiny spots still wet, 24 hours, completely set. I used a 99 cent paint brush and threw it and the sour cream cup away when I was done.Yakima Specific instructions:Plenty of instructions out there on YouTube of how to do it. Be sure to watch those, use wire to hold the cracks together, and use duck tape on the outside to build a barrier/wall for the resin to push against and overlap when you have a crack that goes all the way to an edge. Use a razor blade to cut it away later. Just watch 3-4 videos and you will see what I am talking about.The rivet holes on the Yakima Skybox 16 are 3/16ths. Get a very sharp quality bit and pop them quick, if they get hot by spinning, it will start to melt the plastic, you don't want that. If you use a smaller bit it wont be thick enough to break the rivet and you will spin the rivet and the plastic will melt. Once I figured out it was 3/16ths, it made popping the rivets a lit easier. I replaced with 3/16"(diameter) x 5/8" (long) black rivets I bought in a box of 500 that came in 12 different sizes on amazon.
