Total KUDOs to the makers of "Miracle Paint"!!!! I went through 2 separate kits of plastic repair stuff on my radiator at the radiator neck. The last person to replace the hose cracked the radiator by pulling side-to-side on the hose. Now I have a seam crack 3" down the side of the plastic housing, and at the inside of the elbow. I decided to try the "Miracle Paint" with the standard fiberglass cloth.
- put one coat of paint on the crack + 1" either side of the crack,
- allow it to sit 15 minutes,
- apply the fiberglass cloth, press it down so that it is tight against the crack and surrounding area, and
- apply another coat of "Miracle Paint".
- Let it dry overnight
- Apply a 3rd and 4th coat of paint and let this dry 12-24 hours between coats.
- Since I am fairly inept, and since the 'patch' has been holding now for 3k miles, I can say that this stuff is worth it's weight in a new radiator ($370)!!!
Thanks, Mr. Bergsma, for turning us on to this product.
