Service brilliant. Wonderfully efficient and prompt service and delivery
Urgently needed for a restoration project I am working on. Great service and prompt delivery.
Have never used this stuff before. I found it easy to work with on some small filleting job and it's super light weight which was especially useful for my applications.
Thanks also to classic boat supplies for the fast and hassle free delivery.
