However i have been to mapso and head a LOT of problems dealing with them.
I even had to order The Gougeon Brothers on Boat Construction books from the US because they could not or would not get it for me (very strange for West system's agents).
They didn't have any of the fiberglass i wanted, failed to reply to my repeated emails and finally said they don't supply fillet. The price charged was also was 650 $ for 30 Liters / kg.
Basically mapso deals with large customers and use west system for their own boat building. The lack of demand for small jobs is probably why they do not offer any support or have no time / patience to waste on small sized jobs which is why i had to look for alternatives.
So yah was not a good experience at all ..... and i have all the emails as well.
I received far better support from other companies i contacted, free samples, technical support, engineers checking my progress etc... which is why I contacted west system international to try and find another agent (as its clear west system is a customer oriented company, even for small business / DIY projects.
The book and the web site for West System where superb however they helped me to learn a lot. I even helped translate / pass on some of guides to local fiberglass / boat repair workers to help them solve some of the problems they ran into at work.
