Non-setting sealant

Post by TheOtherLeft »

Hiya fellas,

I'm after some advice on finding some non-setting sealant.

I need to seal a small access panel on my firewall and need some sort of sealant for it.

I have used Sikaflex & Silastic before but it goes hard when cured so is not raelly of much use. I have thought of silicon grease but it will go runny in the engine bay.

I was also thinking of liquid gasket maker (ultra blue) but I think it goes hard when cured as well.

Do you guys know of anything suitable?

Thanks

Last I was in autobarn there were 'non hardening' sealants.

May be what you want.

We use 'D-mastic' which is a non setting sealant that 'skins' when we do some roofing and body work on busses/coaches.

not sure how it would go with the heat in an engine bay though.

you tried sending a sikaflex rep an email???

You can get mastic that forms a skin but still soft underneath.

Just phoned Selleys. The D-Mastic has an operating temp of 10-70 deg C so I don't think it's really suitable for engine bays... or maybe it is but it may get soft.

I've used the selleys mastic on the fire wall/footwell where i repaired some rust. I stitched in some zinc seal sheet that over lapped a lil, couple of coats of paint then mastic inside and out to help seal then more over the top. 4 years on its still good.

There's some permatex gray sealant that Supercheap sell that skins up but doesn't set. It's fuel resistant but not sure about heat.
