So finally today i put the grill and lip and other little bits and bobs back on.
It will remain indoors for the remainder of the weekend and early next week when i will be putting it back on the car. hopefully new headlights will arrive by then , so i can remake my wire harness on the car for the new headlights.
Its going to stay indoors at room temperature for the rest of the weekend and add a little more cureing time. just to make sure. Cold does weird stuff to paint.
