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.

Is there a reason you don't want to use Duratec? Made almost specifically for this purpose really. Bit expensive I guess but it doesn't sound like it would need a lot. 


I filled the worst of the damage which actually went down to the glass with a vinylester gel coat that the mould has on it anyway to make sure it matches but I want to make a couple of changes anyway so I was just thinking out loud as the mess happened yesterday and today it just looked awful.. It is not as bad as it first looked but I guess I have a good weeks work to get it how I want..

I was thinking about getting it to a really good surface if possible and durabuild is good but is quite rippled when I spray it.  I can get a clear coat down really smooth out of the gun so a bit less work. But I do have some durabuild I can use and to be honest I think it will be OK using that then once the master is out then just fine tune that with a clear coat or more durabuild. 

I kept meaning to make a master but I had to get some made fast for customers and it got left.. my mistake but one I will not make again.. LOL..
