i am new to this stuff. i did some experiments the result to the eye was good. today i threw some 98 octane fuel on a item and it was like glue and if you touch it it leaves filnger prints ont it. why is that . any info. is it underbaked ? i dont know how to check my item temp for the curing proccess. i know i should have an IR to check it but dont have cash right now to buy one. is there another way??
