So, a few months back I purchased a 100 lb heavy bag (Everlast 100 year anniversary bag) and have been using it without gloves. I only use wraps when my knuckles got cut, however, the skin seems to have healed and has not cut since then. I only work the heavy bag 2 times per week focusing on power and technique. I was actually able to put dents into the bottom portion of the bag going full force without experiencing pain. I am not training to compete in the ring, I am training for self defense purposes and would not want my hand to break if I was to punch a solid surface without gloves or wraps. I only wear gloves when sparring.
Well, there are different kinds of resin, even of clear 2-part resin. The two main kinds (epoxy and polyester) will both be absorbed by porous materials like paper though turning them translucent unless the paper has been sealed first (diluted permanent white glue or something like ModPodge will work, then dry thoroughly). Then you'd probably want to use only an epoxy resin (Envirotex Lite, e.g.), or a tweaked epoxy like Easy Cast which can soften or become more flexible when thin later when exposed to even body heat.

You can get a new one for around 5 or 6 dollars. If you're loosing sleep over it, just replace it. They're easy to stop - just a tad harder than before. Now they won't close or fit without a 9 volt battery installed, so you have to install a dead one now. Too many people were removing the batteries and not replacing them. Actually, if it is beeping - and even though it went off after it stared beeping - it's likely that is the designed behavior. They would design it to warn you a little bit ahead of time and not when it would stop functioning in 12 hours. You know the battery is fine - how? By pushing the test button on the detector. That only checks that the detector works, which it will - even for a month or two - maybe even 3. After the battery low starts beeping. Buy a brand new name brand 9 volt battery and try that. Miscellaneous: Somebody told me on some A/C ones I have that the 1/2 life of the radioactive element that's used to detect the smoke only lasts so long and (well, yes it would) anyway making it almost useless after 10 years or so. I had another one near the bathroom that beeped whenever someone opened the door after a shower and the steam came out. Wow! A bunch of people here who never inhaled that's for sure! If cigarettes don't set them off, pot smoke sure isn't going to unless you're blowing it right into the detector or it's a party and you can't see across the room for the pot smoke.
