I'm going to use it for sealing a water tank on my model steam engine, which I am making. Sorry I couldn't be of much help. If you read some of the comments for Isoflex, there might be some help there. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by S***H on 12 May 2026* Worked perfectly on shed roof ### ⭐⭐⭐⭐⭐ Expensive but good *by G***S on 15 April 2026* Just a little bit expensive but perfect ### ⭐⭐⭐⭐⭐ Good base to add isoflex *by U***I on 14 February 2020* Used the isofex liquid rubber to seal the tender of my miniature steam traction engine. Unfortunately I missed a spot so i needed to add more liquid rubber. For to repair and cover the area I used the primer to prepare the surface and the adjacent rubber for a better bond. Repair went along fine, tank is now sealed.
