Review on WEST SYSTEM Flex Epoxy 4Oz by Peris Auditore

I used this material to repair a Thule box that was badly cracked. My application called for a flexible yet very strong epoxy. I supplemented the repair with fiberglass cloth and used fillers to thicken and fill. The result was a surprisingly strong repair that left the box looking like new. After everything was cured, the repair withstood repeated washing and sanding before applying paint. I don't want to test the repair destructively, but it seems to me that it's stronger than the original. Mixing was very easy. and a long time of labor was forgiving. There were many instructions and suggestions in the documentation provided. it is great!
