OK.. Long story but I have to get a wet lay mould made from a section of an mould which has some surface issues and I want a good finish. Would a 2K lacquer work or do I really need to use duralbuild?

It is some damage in a mould which I have put some gel coat down into but there is still some small surface issues I just need to fill and polish back.. I am just going to make a master from it then re-make the mould complete anyway so just need to get one pull from it then I can finish off the surface more on the master. 

If you looking for a cheap,quick fix just to pull a master fill the damaged areas with filleting wax. Smooth it out so its just below the surrounding surface. That way you will be left with slightly raised areas on the master that you can flat back and polish.
