I almost exclusively use the EC Epoxy Putty "system" for small moulds .. depending on the complexity of the shapes --

Some moulds I have made as a combination .. "green stuff" tooling Gelcoat, then even out details with the putty, then reinforce with glass-fibre or CF cut-offs as a strong backing

The Unimould system really depends on using chopped strand GF, but it works fine with finer glass-mats or woven --

If you want to use Pre-Preg .. go for the Unimould ..

Do not adjust our mind, theres a fault in reality :-)

Hi guys, Just a quick question about which mould making system i sould use as i have several small moulds to make and im not sure which type of mould would be best, So the items are bonnet vents about 15 cm square however there are extra pieces that direct the airflow these are about 15 cm x 5 cm and have irregular ridges on them, will post pics if i get a minute. So i was wondering if the parts would be too small for uni mould system and the mould putty would be better suited?
