Few years I made one of my high side seats in carbon but had to leave out the moulded slots, first one was tickety boo but the 3 after that were scrap as cloudy in places then pin holes etc also it etched my mould so gave it up as took me 3 hours to clean the mould up.
Tried clear gel...result= cloudy big pants
Tried thinning clear gel...result= even bigger pants.
Best result was first one where I never used gel at all just wetted mould with clear resin and slapped on the carbon....result= few wee pin holes but laquer cured that.
Oh and carbon doesn't like uv rays so needs sunglasses
