Title: Chassis sealant Post by: rickjen on November 04, 2015, 07:36:14 AM Hi all, I am just about to put the sub chassis back into place and refit guards etc. What is the recommended sealant to use in the gaps and joins.?
Thanks in advance rick :) Title: Re: Chassis sealant Post by: crowbar on November 04, 2015, 09:22:54 AM I used windscreen sealant as it just skins enabling easier removal in the future
Title: Re: Chassis sealant Post by: Rod on November 04, 2015, 11:25:13 AM I also used a window sealant (Selleys Butyl Mastic) between the mating surfaces. Once assembly I ran a thin bead of sikaflex along the seam. In the future if I (or anyone else for that matter) need to take the subframe off, all that needs to be done is to run a knife along the seal and the subframe should separate due to the non hardening mastic.

When I worked for O'Briens, they used it all the time and it was a problem down the track trying to get the screens back out. Bostic 5614 non skinning mastic is much better for this sort of use as it IS a non skinning and does stay soft for a lot longer.

I based my decisions on the following post when I went through this process. http://forum.fefcholden.club/index.php?topic=19669.msg121216#msg121216 There are different types of "mastic". I used Buytl as opposed to D. I hope you are right though - I hope not to have the subframe off in a hurry. Once in 56 years is good going. I won't be around in another 56 years to see it off again. Jim are you able to tell me where you can get Bostic 5614? I am a day or two away from knocking the back window out of my ute to put a new seal in. Is this stuff the go?

I am sorry to highjack your thread. Jim I just looked online for Bostic 5614 and the info says it is Butyl Mastic. http://www.bostik.com.au/industry-products-catalogue-sheet-28539-bostik_5614_non-drying_butyl_mastic-m-0-g-0.html Is this OK for the window sealant. I have a tube of the Selleys equivalent. Thanks again. Rod |
