Diamond Finish - 2 Pack GLOSS Clearcoat System (2K Urethane) 220ml We have been striving to find the best 2K clearcoat system available and this is it, once applied it has an amazing wet look finish. Pack Contents : 1 x 100ml Diamond Finish Clear Coat (High Solid) also known as Urethane or Polyurethane () 1 x 60ml Hardener () 1 x 60ml Thinners () Instructions Mixing Ratio 100 Parts Clear, 50 Parts Hardener + 10% Thinners (e.g. 20ml Clear, 10ml Hardener + 3ml Thinners). Drying Times : Air Drying at 20°C, Dust Free 30 Mins, Tack Free : 10-12 Hours, Thoroughly Dry : 48 Hours. Can be polished after 12 hours at 20 °C ONLY MIX WHAT YOU NEED EACH TIME, once it's mixed it has a life of about 15/20 mins max then it has to be discarded. Is it possible to pre-mix your 2 pack gloss clearcoat then keep it in a jar for later use if not all used in one go, or is it a case of just mixing enough to do the job? NO YOU MUST NOT DO THIS, once you mix the clear coat and hardener a chemical reaction is started, similar to epoxy glue or epoxy putty. It will hardened within 15/20 mins, if you mixed the lot you would be wasting product and money, so only mix whet you need each time, you will quickly find the amounts you need with a small amount of practice. We would recommend starting with 10ml/gram or Clearcoat - 5ml/gram Hardener and 3ml of Thinners and see how much coverage you get wer fin this is plenty to clearcoat a 1:24 model with 3/4 coats. Is this safe over decals Yes, 2K Clearcoat is safe over decals, it has been tested on all the major brands : Tamiya, Fujimi, Aoshima, Studio 27, Cartograf, Scale Motorsport MFH, etc. Please remember to apply a few mist coats over the decals before the wet coats. It has NOT been tested on homemade inkjet printed decals as so many brands exist, so please test on scrap first. Is this safe over other paints Yes, 2K Clearcoat is safe over most other paints (acrylic paint, Tamiya TS) once they are fully dry so please test on scrap first. What
