How much did all the material used in this video cost to make this mold?

[ecfibreglassuk]

Hi, it would have been approximately £400.00 , best rgds

One of the advantages of Optimold is that the 5 layers mentioned can be applied wet on wet making the lay-up process alot faster without risk of shrinkage.

If using a general purpose polyester resin you would only be able to build up 3 layer max then leave to cure ,sand and apply further layers this is due to exotherm and risk of distortion from shrinkage that you would expect from a general purpose resin.

What is the working time on the resin catalyst mix?

[ecfibreglassuk]

@GoodScienceForYou Hi Working Time will vary depending on working temperature and catalyst addition. as a rule if adding 1% at 15 - 20 deg C you would expect the curing time to be approx 30min. and at 2% addition of catalyst you would expect approx 20mins. this is based on using a medium reactivity catalyst with a general purpose resin but it is always best to check with the supplier of your resin as some resin types can have a different curing time. Hope this helps
