Silicone grease (e.g. Dow DC4) is not the same compound as silicone sealant
The DC4 grease is a lubricant and remains viscous like a Vaseline type lube.
(DO NOT USE DC4 IN PLACE OF VASELINE in some applications). DC4 is highly
resistant to outside elements e.g. WX, heat, cold etc.
RTV stands for Room Temperature Vulcanization and is a GE trademark as I
recall. The original RTV was a red goop. Now days there are a number of
silicone sealants and not all emit vinegar (acetic acid) as a by-product of
curing. I do not know what the cure by-products are but suspect they are no
more harmful than vinegar.
Some clear silicone sealants make a good seal for aquaria and like doodads.
It is not a cement but may be used as a glue.
