Resin
The product itself works as it should. The price of the product seems a little pricey for the quantity

Great Resin for General Fiberglass Needs
I needed resin & fiberglass to make a small repair on an interior part of my vehicle. This resin worked great, and set up as expected. To get good results, weigh out your resin. Use a scale under your mixing cup. Then add the appropriate amount of hardener drops. Stir as directed. I applied this using a chip brush, and wetted out 3 layers of cloth for my repair. I would recommend this for general purpose polyester resin needs.
