Hey so if done some bike panels in carbon skinning the process went really well right up till final sand with 400 grit the panels have started to peel almost like orange peel on the resin, I'm now completely stuck on how to progress forward

Looks like you've applyed resin after the tackyness has gone so it hasn't bonded to the previous resin coat.
Xcr resin by any chance?  

I think I missed it by half hour, silly me for applying it, yes its xcr, I don't no we're to go from here?

     If your skinning I just use surf board poly resin. .crystal clear, higher temp rating.easy sandandcuresin 10mins if it's warm . final coat adds me wax additive and seals and cures so it can be sanded
