- I also have some used paint brushes for sale. I have both male and female brushes. For more information .... Wait, What?
Male and female?
Yeah. Some have bristles .......
Some don't ....
Yeah, that's funny in a twisted sort of way. What can I tell ya?
Anyhow, that's not why I posted that. My question is, anyone have a good idea for reusing these brush handles for something else, after removing the bristles? - I also picked up some additional Fiberglass Cloth. These have 8 square feet per pack, and cost $7.98 at the local Lowes.
Multiply by 7 and add tax, for a total of $59.22 We can add that to our prior total in the spreadsheet of $11,300.15, for a new grand total of $11,359.37. - Here's a couple of pics checking how the TPO rolls down over the plywood in a 180 degree bend.
Looks like it should be fine. - Here's a close up of the top side after rounding.
Here's the bottom side after I rounded and then pulled out the sander and gave both top and bottom a light sanding, just to smooth it a little bit. - It finally cleared up a little bit today. I pulled the TPO back and proceeded to round o the edges of the plywood. I used a 1/4" round over bit.
- Another wonderful day of liquid sunshine. It's supposed to be nice tomorrow, maybe I can get more work done on the back of the roof. Wahoo!
- Here we go ... Another day of wonderful liquid sunshine....

So far, looks like the Bondo Fiberglass resin over Fiberglass cloth is a winner.
We used that several times to repair vettes. Bondo gets heavy if you use a lot of it.
What surprised me was that it hadn't torn at 535 lbs. It did start to slip in the wooden clamps a little, hence the elongated screw holes on the one end.
The Epoxy tore at 455 lbs and the Por 15 a little over 400 lbs. I want to fasten the ends a little more securely and see how much more I can get out of the Bondo resin.
Then again, my scale tops out at 660 lbs, although, I am not sure I'll get there.
The big difference is cost. Epoxy and Por 15 are around $170.00 a gallon, and Bondo is around $70 a gallon.
The Bondo resin is listed as waterproof, although it is also not completely clear like the Epoxy.
Por 15 is not fully clear either, so it depends on the usage.
However, Bondo with Bondo Fiberglass cloth looks pretty good.- ro_sieExplorerSo far, looks like the Bondo Fiberglass resin over Fiberglass cloth is a winner.

It dawned on me that I had not tested Fiberglass Resin with the Fiberglass cloth for strength.
So, I did just that. Based on the preceding pic, I made sure the Fiberglass Resin over fiberglass cloth was the same width.
I stuck it in my test setup.
You may remember that the Epoxy tore at 455 lbs, and the Por 15 tore at a little over 400 lbs.
Here is the Fiberglass resin test.
This is a little bit blurry, but the scale is at 535 lbs.
This hasn't torn yet, but the I stopped the test because the Fiberglass resin test started to slip at this point. If you look at the earlier pic, you can see the screw holes are elongated, because during the test the resin/cloth started to slip.
So, I am not sure if I want to be impressed, depressed, or thrilled?
So far, looks like the Bondo Fiberglass resin over Fiberglass cloth is a winner.
