Surfing Waves

First board was going great until it came to glassing- please see attached.

for context I mixed it in the correct ratio added some additive F and the temp was above 15 Degrees (I also used the side to side techinque with paintbrush) - Any ideas where i went wrong? (Such a shitter)

Are there any possible fixes...

1) Is this your Hot Coat ?

2) You said you did side to side brush strokes, what about top to bottom / front to back strokes ?

3) What type of paint brush ? I always recommend the "Purdy" brand.

I don't see any glass there so must be the sanding coat? Maybe you let the resin sit too long before you applied it to the board? Most likely you can sand it down

Could be you applied too much resin but solution is to sand it down
