One keytop in 8oz acetone. I should have let Newton answer this one. regards Ralph Martin Martin, darn it, I had to go out in the rain to the garage to get this information. I don't like this cold rainy weather after spending more than a week in Havana!!! Use 5.6 grams of plastic to 8 oz of acetone. Ground material is better than whole keytop because it desolves faster. This can be considered a standard mix. Use more or less plastic to strengthen or weaken solution. Newton
