I used flex 90 to build spring bushings it is really stiff was easy to mix and poor you must work fast , the quality of the polyurethane rubber is exceptionally good and provides exceptional support . In retrospect I wish I had used the 70 on everything I only used it on the shock mounts but if you need something for high impacts resistant the 90 will hold up
Product has worked for my car bushing so far so good. I could not find a basic tutorial anywhere on their website or packaging, I may be blind, but , thankfully it is a straight forward process. Fast shipping as well.
work time is vastly incorrect, i'd say it's closer to 1 minute. It is super thick once part a and b have been added, and it is SUPER prone to air bubbles at room temp, heavily recommend using a pressure cooker to remove air bubbles.
Works as described. No complaints. Order arrived on time in perfect condition.
Fast shipping. I think it is going to work great.My test piece turned out better than expected.
