i've been doing plug kits for few years now and a few problems that have popped up are bubbles in the eyes,i always brush down to the tail to keep any bubbles down there i also exhale on the plug to pop any.after i put them in the spinner i check for bubbles and dripps for the first hour,but i'm still finding bubbles in the eyes.
the next problem is cracks this just started happing a few batches ago.i havn't change any steps.i thought i might of forgot to sand the primer beforepainting but thats not it.
last and most annoying is yellowing i have most of my first kits and use them,there white as snow my newer ones yellow in less then a month.
in the pics i tryed to show whats going on the top plug[surfster]is atlest 3 years old the bottom[danny] less then a year.
the cracks go down to the primer.
the bubble eyes didn't come out to good.
any ideas whats going on.rob
