While I do not use the West System epoxy, a short read of the article shows the graph to be accurate for the West System 105/206(&7) products, not all epoxy. A call to Brownell's tech support is how I found out about heating up the Accraglass gel. The gel has a very long working window, multiple hours not minutes, and heating it a reasonable temp has not created any issues for me. YMMV,
