-In order for the resin to penetrate fully into the glass, it can be heated, or a vacuum can be used (or both, aka autoclave). When mixing resin with hardener, heat will be generated. It's possible to obtain drum or pail heaters. Use caution not to overheat (don't boil resin) or leave heater on for prolonged periods of time.

 In this image, woven roving is used. Strand glass may be easier to soak in, given it does not have symmetrical layers impeding the resin.

-The hardener for polyester resin, [[Methyl Ethyl Ketone Peroxide]] (MEKP), is a corrosive and flammable liquid, and it should be handled with the greatest caution. Keep from children's reach. Wear protective goggles when mixing resin and hardener together. Shake the resin well before each day's use. The heavier components settle to the bottom of the container and must be recirculated. Drums can be up ended and stirred with a long stick. Do not glass in the direct sunlight on hot days. the surface to be glassed gets too hot and can upset the resin's hardening process. Also, the heat will cause the resin to gel too fast, perhaps before it can be totally worked into the fiberglass.

-Note that the MEKP commonly used is diluted, and is not as dangerous as pure MEKP.

 Rig up some kind of temporary shelter with a tarp to provide shade and cooler temperatures or wait until later in the afternoon when the sun is not baking the surface to be covered. In hot temperatures, lesser amounts of catalyst should be used. Do not let uncured resin get rained on or wet.

 In order for the resin to penetrate fully into the glass, it can be heated, or a vacuum can be used (or both, aka autoclave). When mixing drums with hardener, heat will be generated. It's possible to obtain drum heaters. For small quantities, there are heaters for 5 gallon pails. Use caution not to overheat (don't boil resin) or leave heater on for prolonged periods of time.
