Review: Excellent flow rate, levels quickly before becoming tacky - I use this in very small quantities to fill a small void. This product works very well, levels out quickly and dries in a reasonable time frame.
Review: good adhesion, but seems to cause oxydation (rust) on ... - Convenient to work with, good adhesion, but seems to cause oxydation (rust) on the surface of steel, when applied to it. This is the first time we have used it and have only limited experience. Can anything be done to prevent this? Some surface treatment prior to the application of the silicone?
