Recently I got a crack in my radiator and found out its going to be $300 just to buy a new one, and thats If I installed it myself, it was going to be around $500-$600 to have someone do it for me, I looked into other ways and here's what I came up with. Total cost $16, time 15min. lasts forever.
Step 1: Materials
I went to a local napa automotive store, and found a kit that is designed to fix cracks and holes in plastic parts on cars and containers. It's a fiberglass repair kit and only cost about $16.
Step 2: Directions
I followed the directions that came with the kit but there were a few things the directions said to do that didn't work as well as they claimed, I'll talk about what I found that happened or worked better in other parts as they come up.
The kit came with a strip of fiberglass cloth,. sand paper, a metal tube 1 time use brush, and a 2 part epoxy.
Step 3: Other Tools
Some other tools you'll need is a few simple things.
1.Scissors for cutting the fiberglass cloth to correct shape.
2.some sort of tool to scrape off excess material during the cleaning process, I used a small pick, a screw driver would work just as well.
3.A drill and a drill bit, the drill and bit are used to ensure the crack doesn't spread, Ill explain all that in detail
4. air filter mask, I used a simple painting mask, but any filter mask would be fine.
Step 4: Cut the fiberglass
Cutting the fiberglass is really easy. it is just like cutting normal fabric so normal scissors work fine.
Step 5: Preping the area
Make sure you scrape all excess dirt, grease, or any other dirt off, and wipe clean with a cloth or a rag, don't use paper towels because the may leave traces of fibers behind. Then use the sand paper to sand anything off that is left behind, and in order to give the fiberglass a surface to stick to.
