AnthonyMk3AnthonyMk3: I purchased this product in order to play around with resin dome stickers, and potentially more, but was mainly concerned with its longevity outdoors, so I made a small batch of stickers, and placed them outside to see how they aged

The material was very easy to work with, and initially I was very pleased with the results. I opted to let them cure inside a pressure pot, and the final result looked great! I placed them outside before I moved forward with other projects

Glad I did, because as you can see, they aged very poorly, and no, the issue was not with the sticker underneath, which held up amazing. The resin very quickly broke down, this is less than a month of sitting outdoors, granted it was in sunlight all day, in the middle of Texas summer heat.

I would use this for indoor projects, or for anything that won't expierence a ton of UV light. It really was easy to work with (just make sure you follow the instructions to a T, and measure carefully). But very disappointing knowing that I essentially wasted money on this.

BluefinCHBBluefinCHB: Just read the instructions & you'll have great results, as with any resin/epoxy project.
Did my initial seal coat, let that cure overnight. Sanded with 400 grit & cleaned with acetone.
Did my final flood coat, likewise let sit overnight & was very happy with the results.
During the flood coat, I made sure to babysit the drips and keep brushing them away until the epoxy set enough to not want to drip. That took probably a good hour or so, but the results were worth it.
Made sure to stick with the UV rated stuff as this will be living on a saltwater boat.
Have more than enough left over if I need some for light touchups which should be super easy.

John H: I was making some daytime running lights for my old Mustang out of some LED units I bought elsewhere. I wanted a way to make them discrete and fit between the horizontal grill strips on the car but there was no way to attach the LED units themselves. I found this product, which is supposed to resist yellowing due to UV. It's super easy to use. I made a mold, then used the resin to cast the body of the DRLs with the LEDs inside. Following the directions, the product worked very well and I'm very happy with the results.

April: I had no idea JB Weld made this. It's a really great product, though it has some iffy and tedious directions for using it ... temp, etc., that I summarily ignored.
I just mixed it as normal and everything went very well. Crystal clear and very hard where I'd gotten rid of bubbles.

Now, bubbles. It's really no better than any other resin with the exception of a couple of things:
1. If you are making a small batch and have something to heat the resin to remove the bubbles (like a coffee cup warmer), it's brilliant. I'm going to assume the bubbles I got were the result of trapped air that didn't surface until well over 30 minutes because I was encasing embroidery. To be expected and I figured out how to correct for that and it wasn't the "fault" of the resin.
2. I do short pours, or those that I repour to embed objects before the initial layer is hard-cured. You can do this with most resins over a 3-5 hour period after pouring.

The instructions said that it's cured to touch in 5 hours and cured in 12. Because I still wanted it to be a bit boggy (because of what I was imbedding), I erred on the 3 hour side.
NOPE. Let it sit until the "cured to touch" stage,...
