Silicone sealant

(1/3) > >>

thermidorthelobster:
Can anybody tell me if white silicone sealant sold in big tubes cheaply for home plumbing jobs is different in any way from black silicone sealant sold in small tubes expensively for automotive use?

I need to seal up the air hoses and air box drain valve on the Disco for wading purposes, and I don't want to go out and buy ever more sealant from the motor factors at great expense if I can use the stuff that's already in the garage!

Thanks.

George:
IMHO Silicone sealant is silicone sealant. :wink:

Motor factors just like riping you off because they know you're only going

to need a little bit, but still charge you full whack, and then some. ](*,)

I used the common stuff in a big tube ... nothings fallen off yet ;-)

muddysteve:
I've found that the black stuff sold for auto use tends to be polyurethane sealant, very good for car stuff sorkels etc (is what i used) if you need some i can get standard gun sized tubes of black polyU for nowt

That's interesting - maybe that's why the black stuff is slightly less obnoxious to work with than the bathroom stuff.
