not an expert....but it looks like the one on the top of your nose has bleed under the back of your first tape line - did you use thin tape to get your nose curve?

a couple of things
use good quality tape
push the edge of the tape down hard with a razor or hard edge, that applies for not only your initial tape outline but also the tape used to block out the rest or the deck or capillary attraction will make the resin seep behind under the second tape line and will pool directly behind your lap tape.

ps - that is a nice blue

To repair what I see,lift the seeped colour carefully....if that's impossible...then surform as flat as possible and glass the top clear,then glass an insert in full pigment to cover the initial Lam hiccup.

That damage looks to be mostly confined to the tightest part of the radius, as the tape was being applied.

This could mean that a widish tape would tend to slightly lift on the outside edge after it was pressed into the blank, and you may not even notice it.

Search the net for a taping technique that may help in the future, it's hard to explain, but I will try.

You lay the wide tape along all the edges that only have gentle curves, but when the radius start to get tight, you pull a foot or so of tape out of the roll, without adhering it to the blank.

Then using a safe edge razor, your cut the wide tape longitudinally so that you end up with a very narrow section of tape, maybe only 10mm wide. this will then go around the radius much better. You then need to build up with additional tape to get the protective width you need.

There may be an advantage in doing the width layers first, before you do the primary edge layer, that way there may be less chance of overflow resin running under the additional tape.

I think the technique is on YouTube, some guy showing how to do pin lines on a red longboard, perhaps one of the Hawaiian Fiberglass vids.

Found it, about the 1 minute mark.

there's also nothing stopping you from just getting a narrower tape for those areas.

Yep 3M 233+ is what you seek. Not cheap but worth it.
