I am in the process of redoing my transom. I have opted to do a pourable transom. I am planning on going with Arjay. I looked at Seacast and I think it is a good product also. My reasoning for my choice is it looks like the Arjay or Nida bond is more pourable and I will get a more even pour that will fill every void. I would love to hear from someone that has used these products and hear what you have to say. Any feedback is greatly apreciated.
