Fixing Blemishes

I need a little advice on how to properly fix blemishes. I fully realize the whole idea is to NOT create things which need fixing.
( :smiley: If only the government could grasp that concept! :smiley: )

Let me share my latest installment to my composites training tuition, which has culminated into:

Rule #22: Always insure the resin tube is at the very bottom of the pot.
&
Rule #23: Do not shoot the bull while doing your infusions.

Watching bubbles come up the resin tube, when everything was otherwise good, is extremely upsetting! I think I was lucky, because had a hemostat right there and pinched it down before they entered the bag. Only I was short those last few flOz of resin. So, I walked the bubbles back down the tube, (at ATM), so I could give the part a little more to drink. Bubbles were inevitable. (That said, it was humid, and I didn’t feel completely settled about how long I degassed.) In any event, I realize I screwed up. But, I’ll get better! :smiley:

In the mean time, how do I fix my mistakes? What can be done when it’s so close!?

I’ve taken Adam’s advice on painting a 2k Urethane into the mold. (Adam, you’re brilliant!) My voids are behind a thin layer of Urethane. What is the best way to fix this sort of thing?

Sand down the clear, then fill with resin, sand and reclear.

How is the bull doing?

I was afraid you were going to say that. :sad:

:smiley: No bulls were harmed in the infusion of this part! :smiley:

That said, I prefer being understood over being funny. I realize I should refrain from using old American idioms in an international forum. In case that phrase doesn’t make sense to anybody:

“Shoot the Bull” - Boastful, senseless or shallow talk; Lying; Wasting one’s time by talking;

I had to look it up… (slang dictionary).
