what i learned my 1st time: don't crank the lids down really tight as it SUCKS when ya can't unscrew the lid n it's hard to find a pliers that large.
oh yea, remember to be able to laugh at yourself when ya do stupid sh*t like that as it's a learning process n enjoy the process funk ups n all.
n on the topic of screwing up, don't put everything you have(supplies) into your 1st try as if something goes wrong it's nice to have supplies left over to do it again right(pf-tek to the letter will not fail).
