Hi, have a new project on my car and making an glassfibre frontspoiler with carbon skinning on top. Big issues with the resin cure.
I have now put 5 layers of resin and everytime i want to sand the surface flat the resin clogs up the sandpaper. the resin is still litlebit sticky after 24h. I have also tried to let the resin cure 48h but when sanding allways the resin is clogs up the sandpaper. 
When sanding the sticky part of its fully cured under it. what is the problem here?
