Troll Hunter Posted March 21, 2012 Share Posted March 21, 2012 Hi, All, I need some advice, please. I'm doing my door rebuild, cutting out rotten steel frames and welding in new sections. At least, that's the theory! As promised in my post some months ago, I'll post a report, together with some horror piccies, when completed. Can anybody please recommend an adhesive to put between the aluminium skin and the new steel frame? It seems that the adhesive acts as an insulation between the dissimilar metals, to reduce electrolytic corrosion, and also reduces drumming of the door panel. As far as I've been able to find, using Google, are a number of products by LocTite, and a couple of other manufacturers, but they all seem to be epoxy based and to set rigid. Would such a product be suitable, or does it need to retain some flexibility. I ask because the old adhesive, even after 21 years, is still slightly flexible. Alternatively, could a silicone based product, eg bath tub sealer, be used? Any advice will be very much appreciated, and thanks in advance.

CwazyWabbit Posted March 21, 2012 Share Posted March 21, 2012 Have a look for the sikaflex thread on here from the last week ..... that stuff sticks really well and remains flexible EDIT: http://forums.lr4x4.com/index.php?showtopic=75082 Quote Link to comment Share on other sites More sharing options...

Phil Hancock Posted March 21, 2012 Share Posted March 21, 2012 Sikaflax for sure. Quote Link to comment Share on other sites More sharing options...
pat_pending Posted March 21, 2012 Share Posted March 21, 2012 Or Tiger seal. In fact any pu adhesive sealant. Quote Link to comment Share on other sites More sharing options...
DrRob Posted March 22, 2012 Share Posted March 22, 2012 Not a silicone based one as it will "interfere" with the painting process!!! Quote Link to comment Share on other sites More sharing options...
Dads Toy Posted March 22, 2012 Share Posted March 22, 2012 Sikaflex is often recommended for Land Rovers where you need to stick something, but which one? I had a quick look and there seem to be quite a few! Malcolm Sorry, just found the thread in "Tools & fab" Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted March 22, 2012 Author Share Posted March 22, 2012 Many thanks for your responses, everyone, and particularly for the link to the Tools and Fab. PU is obviously the way to go. I must admit that when I read the first three responses I suspected a wind-up. I've never seen such anonymity on this forum!! Mike Quote Link to comment Share on other sites More sharing options...
Tom1809 Posted March 27, 2012 Share Posted March 27, 2012 What happened to using seam sealer? Quote Link to comment Share on other sites More sharing options...
antony110 Posted March 27, 2012 Share Posted March 27, 2012 I read once in a LR Mag to use gaffer tape on the door frame first and then put the sealant over the top to stop the dissimilar metals corrosion problems. Have you thought a bought galvanising the frames as well? I think that's going to be my route when I come to it Quote Link to comment Share on other sites More sharing options...
