SILICONE ALTERNATIVE. For all those who do not like silicone, try a polyuethane elastomeric sealant, like the Sikaflex range. Superior adhesive
range between different materials. When cured virtually indestructible. Can be used in aggressive enviroments, so an I/C engine
room no problem. Potable so no contamination of water. Can be used under water. Can be sanded, though idon't recommend. I prefer to use some spittle from the hand as a final smoothing agent before curing. Can be overpaint
ed with any paint system
. Downside, it's expensive, but you will not be buying by the box only a tube. From any good build
ers merchant or Amazon.
