Just a rule to live by. Sometimes I don’t; like on the gloss coat for my kid’s new board. Was it a dirty brush, or contaminated by a compressor that was just drained and had “stuff” still in the line, or did I just not clean the board off well enough? Anyone care to share some of their mess ups or, am I the only one? Time to take it back to 60, and do it again. The only thing I hate more than a bad gloss is polishing one.
Well at least that is an easy fix. Not thinking straight= Mess up too. I’ve lammed half of a board with tinted resin only to realize that I am completely out of resin. not even anymore in my shed to whip up another batch with. I learned my lesson though and it hasn’t happened since(knock on wood).
thinking straight is hard to do with styrene fumes around.
Trying to rush through your fin box install is a good way to ruin a day! Did this on my last board & ended up routing one box with the target backwards & the other got lined up on the wrong hashmarks. Luckily i caught it before i actually glued the boxes in, but what a pain in the ass. Drinking beer during the process, probably not a good idea either 
Did a lammed fin repair for a kid right before a contest and forgot the catalyst. The darned thing just wouldn't hold. ???
What an idiot! Had to find another board for the Lad to ride in his heats.

The other side of that coin is forgetting that you added catalyst, and adding it again! Now I haven't done it, but I've seen the result when it happens. Besides smoking, the resin pops like popcorn in the bucket, it goes off so hot. Actually dangerous. Could start a fire.
Oh, I've been through the "popcorn" routine too. Set the bucket in a pail of water.
Epoxy bites me on the ass more than anything else, it is almost 100 % me being disturbed will measuring out the components, once it was 2 parts activator to resin, the other times, resin and no activator, or not mixing the 2 parts, can’t you see I’m working over here !
Too much catalyst, or none at all; how much epoxy or hardener (since I mix with the same containers) yeah done that too. I while back someone posted up that they didn’t make mistakes, well I still do, but I try not to make the same mistakes over and over, and always the common denominator is rushing.
never rush it.
it doesn't pay.
bad tude days will kill faster than a bullet.
mix that with toxic... vile.... extremely.... flammable ........burn forever plastics..........
and you got a bomb.
take care,and .............
.........stay alert.........stay alive.........it's as simple as that.

Not exactly a mess-up as it can easily be fixed afterwards, but it has happened to me quite a few times; I build mainly longboards with a finbox and a through-the-box-and-out-the-deck hole for the leash rope. Here comes this young lad who asked me for a 5’4" “copy” of a famous shortboard model. I had just finished polishing his brand new toy and I was pretty satisfied with what I had done, not being that familiar with shortboards. So I hand him the board and ask how he likes it and he goes: “Uh… Where do I attach the leash?” DANG! Forgot to install a leash-plug…
Just layed down a gloss… 200 ml, thought I put uv in …? 5 drops of cataylst just to cure what falls on floor.
Put it in the sun, guess what …?
This will go off, eventually ?
Story of my life!
Last summer, I was rushing to finish a board for a kid whose brother was coming to town for a visit and would be taking it home for him. Got it done, had it wrapped up for shipping, then turned out he was going to be the one to pick it up. He gets there, I put the fins in it and wouldn't you know it, my dyslexic mind had put one of the Fusions on the wrong side of the line so that the outside edge of the fin was sitting where the inside edge should be. Jaime picked up on my reaction, which had to say it all (sort of a combo of "having seen a ghost" and "oh shit!"). Gave him a board to ride for the day, routed out the fin box and installed another in true "hurry up" fashion. Luckily, I got that one right and you can hardly see the f**k up. Yes, he got a discount.
Rush is a four letter word. I once did a acid splash and forgot to add the cat. Went to lunch came back to cut and WTF!! it had drained out all over the place. Pulled the cloth and did another splash and no one knew. The mess on the floor well lets say I had sticky floors for a few days. Then there was a all black cover up I did on a CI fish. I got all kinds of shit for doing a black lam. Yet when it went to the shop it sold in the first hour?
I found out that if you install a Future box backwards you can just cut the fin to match without ruining it for use in properly installed boxes. Mo bettah to install the boxes properly, though.
I also found out that when gluing PU rails on an EPS core it pays to skip using Gorilla Glue; and, more importantly, it pays to completely fill the seams prior to glassing. No, a veneer overlaying the seam will not “cure” the underlying flaw because an open seam on the rail will inevitably attract a ding and proceed to leak water - and veneers look like shit once water hits them from underneath.
