Half model 2

 Unfortunately,  my timber has pine resin, knots.  In addition, the bow part has some flaws so I needed to fix it. Actual process is coating the epoxy resin on the plug, however my half model had some scars, so I used another processing. My tutor suggested me to use "Dura tec" instead of epoxy resin for coating my plug.  It can cover all of bump surface of my half model and it is easy to do sanding.

       For using 'Dura tec' , we need a catalyst as well. M.E.K.P (Methyl Ethyl Ketone Peroxide)  is common catalyst with polyester resin. Normally, put 2~3 precents of primer's weight, so I used 1370 g of 'Dura tec' and added 30ml of  M.E.K.P

Primer (Dura tech) + 3% of Catalyst (M.E.K.P)

1370  + 30(M.E.K.P)

I used an air brush for coating 'Dura tec'. One of important thing when we work in F.R.P is wearing safety equipments. The materials are flammable and poisonous. It would really harmful for human body. That's why we have to ware safety equipment and must know how to deal with when emergency happened.

To fill the gaps, I brushed thickly. After drying Dura tec,  my group and I sanded the surface of the plug until all of scratch disappearing.
