This might be a stupid question but, when I read the application instructions for the uni mould system it says I need to leave the gel coat to dry and I assume the same for the coupling coat before you apply the 4 layers of tooling coat however, when you watch the carbon bonnet video you apply the coupling coat when the gel coat dries to a tack. Which is the best way to go to achieve the strongest results?

Yes you want the coupling coat to be cured to at least the firm but tacky stage.
