Review: Great Product at a Fair Price - The product is something that I have used for years and like very much. I will comment on something that others have noted in their reviews. The packaging was not up to the job of protecting the cans. Fortunately my order was only slightly damaged. I remember reading the reviews prior to purchasing from this vendor and reading the horror stories about badly damaged shipments. I was on the verge of not buying and moving on but decided to take a chance. I wonder how many sales are lost because of reviews mentioning shipping damage. Also, the poor reviews are consistent and go back a long way. So why does the poor packaging continue?
Review: It dose what it tells you - Work very well

## Features

- CONVENIENT EPOXY BUNDLE contains one can of WEST SYSTEM 105-B Resin (126.6 fl oz), WEST SYSTEM 205-B Fast Hardener (27.5 fl oz), and one set of calibrated 300 Mini Pumps. 205 Fast Hardener is a medium-viscosity epoxy curing agent. It is useful in a majority of bonding situations, and at lower temperatures. 205 Fast Hardener produces a rapid epoxy cure that develops physical properties quickly at room temperature.
- 105 EPOXY RESIN is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with 205 Fast Hardener at a 5:1 ratio, it cures to a hard, solid plastic with superior physical properties. It will wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals. (205 Fast Hardener is not intended for clear coating.)
- POT LIFE AT 72°F (22°C) is 9 to 12 minutes. Cures to a solid state in 6 to 8 hours. Cures to maximum strength in 1 to 4 days. Minimum recommended working temperature is 40°F (4°C). Does not contain VOCs and has relatively high flash point and no solvent odor, making it much friendlier to use than styrenated resins.
- EXCELLENT FOR COATNG OR BONDING, this epoxy is easily modified with WEST SYSTEM fillers, pigments, and additives to suit an enormous variety of construction and repair projects, including fiberglass boat repair, strip kayak and canoe construction. Resin viscosity is approximately 1000 centipoise at 72°F (22°C)
- INCLUDES CALIBRATED PUMPS that dispense 105 Resin & 205 Fast Hardener at the correct 5-part resin to 1-part hardener mix ratio. One pump stroke of resin for each one pump stroke of hardener yields 0.8 fl oz of the exact 5:1 epoxy mix ratio. These durable polypropylene pumps provide years of dependable service.

## Questions & Answers

**Q: Can you recommend pigment for woodworking?**
A: I haven’t tried any pigments but I do use saw dust mixed in with it occasionally

**Q: About how many square ft. (plywood) would this product cover?**
A: I can't tell you about plywood because I used it on red cedar and cherry wood. I covered 120 Sq. feet over fiberglass over cedar which is very absorbent. I used one can and got three coats  of coverage. You should get more because plywood isn't as absorbent. Great product, has long shelf life! Hope this helps  Good Luck. Capt. George

**Q: How thick is the solution just after it has been mixed?  Is it similar to thick syrup or runny like water?**
A: The mixed epoxy is syrup like.  It Wil tend to sag & or run on a vertical surface if applied to thickly.  I tried brushing, rolling and spraying for the final few layers of exoxy

**Q: can you use this for molds, crafts?**
A: You can but it’s not crystal clear. It builds up in my mixing cup over time and has a yellow color to it when thick like that.
