If you’re as old as I am you may remember some of the auto body repair techniques of the late 70’s and early 80’s. It was an era of body fill ,shape and repair rather than today’s replace replace replace. While Bondo is still used in the automotive industry there are so many other uses for this stuff its ridiculous.
What I like most about Bondo is the fact it will not harden in the can and you are able to store it almost indefinitely. The other amazing quality about this stuff is it hardens and is ready for sanding and paint in under 15 minutes.
Repairing The Porch With Bondo!
Recently I noticed the columns holding up my covered front porch were showing signs of rotting at the very bottom. Apparently some of the caulking around the top of the column weathered and was allowing moisture in the pole and causing rot.

Tools you can use:
I completed the entire job with just a few basic tools.
A can of coil cleaner Nu-Calgon 4171-75 $14.12 at Amazon
I used this specific coil cleaner on my units and it works as designed. The thick foam lifted the dirt and grime for easy removal. The label said its a “self-rinsing” formula using the coils own condensation to wash away the dirt. I still used my hose to wash away the grime. One can was NOT enough for my 2 units.
A good cordless drill similar to this one from DeWalt
Any cordless drill with a decent amount of torque will do just fine.
Magnetic socket nut driver, I used a 5/16″ driver like this
The screws on my unit had a 5/16″ head and using the cordless drill saved me a ton of time. You can use a hand driver or a flat edge regular screwdriver as well. The screws on your unit may vary so take a look before you buy any new tools.
