You can apply more layers within a 24 hour time frame, though I would scuff up the surface with 60 grit paper and clean well with acetone regardless. If longer than 24 hours, make sure you scuff up and clean. The problem with tooling resin is it actually needs to 'self-bake' to achieve its full properties, and it needs a minimum of 3 layers of 450g csm to do that. If you didn't get that down, then are you able to apply more layers and do an elevated temp cure? If you can get it up to 60 degrees minimum then you may get away with it.

The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind... 103% of all people do not understand statistics... Do not adjust our mind, theres a fault in reality :-)
