...hello hello

like others i'm sure, now and again i need to use a little 'mastic' on the car. this time to seal up a leak....

there are so, so many 'tubes' out there, i get confused. Am I righ tin thinking some mastics have to be avoided at all costs, due to acidic vapours when they cure??? etc. etc.

Can anyone tell me the general rule with mastics????

The job in question is to seal between rubber and bodywork to stop leaks, so must be waterproof and flexible and stick to rubber / metal.....

Thanks
Will

Bathroom sealant, as sold by your average DIY superstore.

Go to a proper motor factor and get bodywork sealant.

Tiger seal or Sikaflex are both ideal for automotive applications.

just to clarify...

bathroom sealant = acid vapour / no no
bodywork sealant = seal sealer??

thanks

Correct. Not all, but enough to avoid.



No, seam sealer tends to be brush-on. The mastic I'm thinking of comes in tubes very similar to bathroom sealer. Often used for window seals, badges etc.

great - thanks matey

going to go with Neil's suggestion of tiger seal or sikaflex - is thsi the stuff? http://www.screwfix.com/prods/79250/Sea ... y%20300ml#

That looks more "house" than "car" - just wander down your local factor, see what they've got on the shelf.

all the time avoiding Halfrauds....i'm guessing

they have got an offer on oil at the moment though - part-synthetic though, so only bringing it down to the cost of 15/40 mineral anyway...

As "rules for life" go, it works for me.



I've paid a snidge over £3/litre for Fuchs full-synth, delivered, the last couple of times from Opie Oils.

There are many different types of Sikaflex on the market - you'd be better off reading up on it & choosing the one suited most to the application.
