What silicone/sealant to use

Finally running solar wires from panels to controllers. Had to remove silicone from hole punched through floor to wheel well.

What exactly is this? Want to make sure I replace like for like.

Thanks

It's not silicone unless someone has removed the original already, I have replaced my sealant with polyurethane, it last well and don't break down like silicone does.  Send Brad Wolf a private message he can tell you what it is

The goop that Foretravel sealed every thru-floor hole in my coach sure looks like white silicone...and gobs of it.  It is tough as nails and tough as hell to remove.  I sealed back all the openings with white Lexel after I poked my new wires through.  It sticks to anything and cures quickly.  Woody.

I think the original stuff may have been Silkaflex. Brad has mentioned it before. 
 I like it because sticks really well , easy to tool and seems to repel dirt.

Bob is correct.  It is Sikaflex polyurethane.

Thanks for the help.

What was there definitely seemed like a robust silicone. Fairly easy to remove, it remained pliable with no cracking or deterioration. Looks like it was factory installed but you never know.
