Make a Keychain From a Car Badge With JB Weld

* Use short video tutorial (above) if you don't want to read! *

------------------------------------

JB-Weld is used for many applications. This tutorial will show you how to mix JB Weld in small portions so that you can get used to working with it and curing it properly.

Generally, JB Weld is used to fix cracked plastic covers, fenders and numerous other things, but this tutorial is just a sample of how the 2 part epoxy works (similar to most other 2 part epoxies).

If the mix is right, the bond will be very sturdy, but if not, it can be prone to failing - especially when there are only small areas that need to be bonded (like a keyring to a car badge :) ). You may be better off using epoxy resin that hardens like fibreglass, but even fibreglass bonds will break if used to attach things like keyrings to (heavier) tools, etc.

I will soon make a video showing cracked plastic fixed with JB Weld, but do not have enough at the moment.

------------------------------------ Detailed Instructions Below

-JB Weld

-Gloves - JB Weld contains Bisphenol-A... Yay for dangerous carcinogens!

-Xacto Knife/Razor

-Keyring

-Q-Tip/Popsicle Stick

-Old Business Card

-Gloves

-Rubbing Alcohol

-Object to add keyring to

Optional:

-Paint to paint JB Weld

-Clear coat paint to seal your work

1- Roughen surface with sandpaper (if you have it)

2- Make cuts and scratches on area of badge and keyring that will contact the JB Weld epoxy

3- Clean with rubbing alcohol to remove dirt and grime

1- Put equal amounts of the hardener (red tube) and epoxy (black tube) on cardboard

(You will want a 50/50 mix of each...Too much hardener (red tube, grey colour) is ok, but too much epoxy (black tube, black colour) will be gummy when cured)

2- Mix with card by "wiping" and folding the mixture, making sure to remove all air bubbles

(You will need to work quickly as this can set within 5 minutes)

1- Take a Q-Tip, popsicle stick, etc. and dab a small amount onto your tool

2- Apply the epoxy to both surfaces and join the ring to the badge

3- Place badge and ring onto cardboard/paper to dry (can be sanded when cured)

*(You can balance the keyring on the Q-tip while it dries if you want the ring to be flush with the surface of the badge- Otherwise, just place it on a piece of paper and sand it down after, which is much easier)*

4- Curing:

-Make sure to let the epoxy dry overnight (around 12-15 hrs). If the mix still seems soft after a day, try to cure for a couple more days. If it's still soft your mix was not correct

(If needed, you can sand and paint....I did not, as the grey blends with the JB Weld decently)

1- Sand the area with 800-1000 grit

2- Tape off badge and areas that you don't want painted

3- Prime the area with a few thin coats of primer

4- Sand primer with 800-1000 grit

5- Paint the area with a few coats of base and clear

6- Let dry and put it on a keychain!
