Outer Limits 4x4 Board

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???

What is that black or grey stuff they use to hold the plastic behind the door cards on?? that might work!!

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.
