Hi.

Ok happened my fault.
I did not steer resin enough or used wrong ratio, after 5 days still have few soft spots on my part.
What can I do to fix it?
Or it cannot be fixed and i have to scrap the part.
Part das not need to look nice it is bottom part of my bonnet.

If you haven't already done so then i would recommend watching our video series on making a bonnet. It covers exactly what you are doing.

If the frame is reasonably stiff, then use only one layer of cloth on the surface so that your bonnet skin has a balance laminate and is less likely to warp.  Probably unlikely to be a major issue but on a good sized bonnet, you could knock things out a few mm  with warpage from an  unbalanced laminate. Usually that is within tolerance of adjustment on the latch and  hinges though.
