I have thinned epoxy with 90% rubbing alcohol and acetone, but be careful, you can make your epoxy rubbery and weak if you go too far. I have never thinned West Systems before, it is pretty thin straight outta the can and sands great too.

Use heat to thin it, if you add thinners you compromise the strength and cure of the epoxy. Heating it up thins it out & helps get the reaction going. Just get it warm, too hot and you will also lose strength. Warming the surface you are going to apply it to is also a good idea as it helps keep the resin thin to soak into any pores & keeps the reaction going for a quicker cure time.

NEVER THIN WEST SYSTEMS WITH ANY KIND OF SOLVENT!!!!!!!!!!!!!!!!!!!!!!!!!! You want to mix stuff into it, use the additives made by Wests for best results

I personally do not thin my epoxy's in any brand -Have I, yes- BUT go off thinning epoxy it can mess with strength dry time etc, you CAN thin epoxy by heating it up BUT it seriously reduces work time, ive had some that went from aprox 70 min work time (was special epoxy not off the shelf) to less than 5 min basically was starting to set as it cooled. Some you can get away with mixing it with above 90% rubbing alcohol but set time is affected and who knows what else it may effect. A good thin epoxy (youll never need thinner) I like is aeromarine it used to be labeled as "green", their "red" was thicker but the number should be the same 300/21 if you buy it call or email to check easy to mix wasnt critical to the ratio being a little off and is just as good as some of the "more expensive" brands, bob smith has a fairly thin finishing epoxy its not as good as the aeromarine nor as thin, when all else fails contact the manufacturer of the epoxy your using and ask them what can be used if anything to thin the product they sell..Hope this helps a little
