Decided to fiberglass my flat roof my extension,measured up and rang fiberglass direct and placed my order,delivered fine but ran out of resin just over half way!!! Then needing some resin quick to finish my roof,some told me of CRS, local to me.I purchased 25 liters of resin from them to finish my roof.I mixed the first mix and gave it to my friend how was rolling it out on the roof (how used to for a boat company laminating) In the first rolling out of the resin he said this is far better resin which made it a lot easier to saturate the glass mat,give a superior finish when the top coat was added.The product was more expenses from CRS, but that is reflected in the product,which is better to work with and gives you a better finish.I would go to them again recommend to anyone who are looking from fiberglass products,especially if its your first time using resin.
