Hey all. 

When having to repair an existing part what is the best way to find out what resin the part is made of?



Is there a simple method to detect the poliéster or epoxy? 





I have been told to burn the resin and detect the color of the smoke (black = poliester ,  colourless = epoxy).

This obviously is not a very practical method with existing parts that need repair.



Thanks in advance.

"epoxy doesn't stick to polyester"



Thanks again Hanaldo .... its exactly that statement that was getting to me.... Had it as a golden rule from all the theory ...
