You'll have to either check the tube or look up the data sheet for the product.

The one I purchased from bunnings is parfix brand and says roof, gutter and concrete on it and is clear.

Generally silicones used for steel roofing is non corrosive and neutral cure. Silicones used for tiles and bathrooms generally are not. But as mentioned, it should clearly state this on the tube.

And i also use the parafix silicone from bunnings, has worked well over the last couple of years

Dunno if this is true or not, but I've found that the 'sweet smelling' caulk is acidic whereas the water-based stuff (odorless - acrylic) is not.

I agree.
