WEST SYSTEM 105 Epoxy Resin 1kg - Clear Resin for Deep Pour Casting, Wood, Metal & Fibreglass Repairs- Marine Grade Epoxy Glue for Woodwork, Repair and DIY - Pair with Hardener for Use

I use this resin to repair wooden windows and frames that would otherwise need to be replaced. Last replacement cost for 8 windows was £20K so this focusses the mind. Used properly the repairs will outlast the rest of the structures so of excellent quality if you do it properly. I am allergic to this stuff so have to handle it with a great deal of care, but the results are so good, it is the basis of my preferred maintenance system as a very active DIYer. I previously bought the next size up, but my needs are declining so this fits the bill.

Just the job I hope
