Review: Rigidizer is how we stay healthy - This material is very much akin to a milk consistency, though clear. In order to make sure you have adequate coverage buy more than 2 bottles. I bought 4. They say it covers well but for my own peace of mind I would prefer to apply a fairly generous coating for permeation of the fibrous material. Will take pictures and post an updated review after the first firing of the kiln. I have read suggestions such as applying a dye to the liquid to make sure you know what you have covered. I recommend that. As it is clear and once applied to ceramic wool fiber, you can't tell what has and has not been covered. ## Features - HIGH TEMPERATURE INSULATION - This coating increases the insulation value of ceramic fiber materials and can with stand temperature up to 2300F - HARD SURFACE FINISH - Rigidizer makes the surface finish after application with increase resistance to mechanical abrasion and helps flexible ceramic fiber material from being too flaky - EROSION RESISTANCE - Rigidizer increases surface erosion resistance for surfaces exposed to high velocity gases - EASY TO APPLY - Because of it low viscosity its application on ceramic fiber materials becomes very simple. It can be applied with brushing, spraying or dipping. It takes around 24 hours for curing post application.
