This is very good advice! However, it takes a bit of effort but it will tell you where you're going wrong in all likelyhood.

New plugs and new moulds are always much riskier than seasoned moulds, They are prone to outgassing, porosity, lack of complete cure etc. If there's any stage of mouldmaking to take great care with it's new moulds!

Don't give up! It's not an easy thing to learn, but the payback in personal gratification is well worth it! is offline Find More Posts by
