MikeThomas Posted July 28, 2020 Report Share Posted July 28, 2020 Morning all. I purchased the glass rear seal from Moss, they are recommended as the best. However the seal is to big for the glass. See attached photo. Any point in asking for another one or do I have to cut it? TIA Quote Link to post Share on other sites
Motorsport Mickey Posted July 28, 2020 Report Share Posted July 28, 2020 Won't be too big when fitted correctly to the Surry backlight frame first. Cram the seal well into the bottom most acute corners first and hold in position with masking tape around the seal and Surry frame. Then cut the tape and extract it when you get into the corner for the rubber to glass fitment, the rest of the seal then prevents the corners wiggling off the frame. I believe this is how Stuart does it and he recommends the Moss seal and he's fitted more Surry backlight windows than the rest of the Register combined !

Tim T Posted July 28, 2020 Report Share Posted July 28, 2020 I've just fitted my first screen and it was the backlight. Used a Moss seal with Moss finisher, it worked fine. Finisher goes in the seal first. I could not see how it would work but as you persevere and progress it becomes obvious that it will. Used minimal lubricant. I think that when fitting the seal it should be snug all round with the excess in the acute corners. You can see that the radius of the glass is very much tighter than the frame radius and that is where the excess rubber goes. Good luck and believe, I did! Tim Quote Link to post Share on other sites
MikeThomas Posted July 28, 2020 Author Report Share Posted July 28, 2020 (edited) Anyone reading this post then please read the correction by Stuart (eight posts further down) Mike Hello Mick & Tim Really appreciate your time and expertise re this. I would have liked your posts but there is no facility to do this, maybe you are moderators? Anyway, I have received the following email from Moss who have been prompt and helpful. MOSS Hi Mike Generally you do fit the rubber to the glass but in this instance the seal needs to be fitted to the frame first, it needs to be pushed hard down into the corners by the “B” post, the rubber does appear too long as there is access, this will need to be taped up to hold it in place, then fit the glass to the rubber and then the beading. The rubber will shrink over time this is why it is this long, we have experimented with the lengths, tested and fitted these screens here in our testing area. If the rubber was shorter it would shrink and leak at the corners. Kind Regards, Adam Chignell R & D Technical Support Moss Europe Ltd MOSS ENDS So it looks like you are all barking up the same tree! Thanks guys and best wishes, Mike Edited July 31, 2020 by MikeThomas Quote Link to post Share on other sites
Tim T Posted July 28, 2020 Report Share Posted July 28, 2020 When I spoke to Moss I was told to fit to the glass! When I asked for advice from two other TR specialists I was told to cut the seal and shorten!!! Definitely not a moderator and not supportive of the removal of the liking facility.

Nigel A Posted July 28, 2020 Report Share Posted July 28, 2020 (edited) I had the same problem, but after discussing it with Jeff Marks at Moss I persevered and it was a perfect fit. Nigel Edited July 28, 2020 by Nigel A Quote Link to post Share on other sites
Tim T Posted July 28, 2020 Report Share Posted July 28, 2020 ... just to be clear, I did fit mine to the glass as advised emphatically by Stuart. Probably one of the most satisfying jobs of the rebuild as I never thought that it would work. Tim Quote Link to post Share on other sites
tr graham Posted July 28, 2020 Report Share Posted July 28, 2020 They do appear to big at first , but by the time it’s all together it is needed so do not cut it , I used plenty of lube and it was all in in 30 minutes. Graham Quote Link to post Share on other sites
Motorsport Mickey Posted July 28, 2020 Report Share Posted July 28, 2020 If Stuart says fit the seal to the glass then I got it wrong, listen to him. However the consensus is the seal length is correct, don't cut it. Mick Richards Quote Link to post Share on other sites

Thanks guys and best wishes, Mike Sorry but thats cobblers! The rubber is too long as already stated so the excess goes all the way down into the corners but I dont see how you could fit the glass into the rubber when its already in the frame as thats not how those rubbers work, I fit the rubber to the glass then the insert and then fit the whole lot to the frame. I have confirmed this with Jeff Marks who is Moss technical director and Adam is going to get a rap over the knuckles! Apparently he was confusing them with MGB and Mini ones that need to be fitted that way. Stuart. Quote Link to post Share on other sites
MikeThomas Posted July 29, 2020 Author Report Share Posted July 29, 2020 Thanks guys for all your input, for some reason I am unable to 'like' any of your posts. Also a big thank you to Stuart for clarifying matters. Going to find another seal fitter local to Coggeshall, Essex. Best wishes, Mike Quote Link to post Share on other sites
Eddie Trickett Posted August 12, 2020 Report Share Posted August 12, 2020 I assume this would apply also apply to a perspex rear screen. Are there any downsides to a perspex screen? Thanks Eddie Quote Link to post Share on other sites

MikeThomas Posted August 27, 2020 Author Report Share Posted August 27, 2020 Update Rear glass was fitted yesterday with no issues and I would like to thank everyone on this thread that has helped and in particular Stuart . I have added the instructions on fitting below so as to help anyone searching and who were worried like I was about what appeared to be an oversize seal. A couple of weeks ago Jeff Marks from Moss-Europe sent me an email and called me to explain why they make the seal longer for the rear glass. Jeff was also happy for me to post his instructions below with a view to helping others who might need to replace a rear glass seal sometime in the future. Instructions rear glass seal surrey top TR5 - Part no 902349 Although the seal seems to be too long, without this extra length the seal will not fit correctly into the lower front corners, we put a lot of time and effort into achieving the optimum length. Start by finding the join and fit this at centre top then push the seal onto the glass working equally to both sides in turn without any lubricant and do not pull it tight along its length. When doing so when you reach the lower centre you will have a loop of extra material, loosen the seal along the lower edge and fit the center of the rubber to the glass. Then work the seal onto the glass working equally to both sides in turn, you will find that the rubber needs to be “worked” on to the glass. When fitting this to the aluminum frame we use a washing line as it is strong, doesn’t stretch and pulls out of the seal well, we always do the job with two people one working inside and one out pulling the line out equally to both sides and helping the rubber to lip over as we go along where necessary, this gets tricky on the corners and patience is paramount. We use silicon spray to lube as we go but this might terrify your painter as paint and silicon aren’t good together when applying the paint.
