Tam n pups winter trip 2022

Do you reckon that seal/cover strip will come off so u can get some real sealer in behind it?
Possibly. I'm not sure though. Problem is the screws go rusty then they snap when removing. It seems well fixed at the minute so I might just put a 6mm Bead around it.

It has that infill bead in it too which I've ordered new stuff for that. ..I'll run a thin bead of sealant over the screw heads before fitting the new infill

Why not use SS self tappers? If I can get the screws out of mine I replace them with SS
 
Speaking from experience of having to remove the whole front of a caravan years ago I would remove the strip. You can refix with new as above just drill a hole near the broken screw. U can then get the sealer in where it needs to go.
What's it screwed into? hopefully not rotten wood!
 
I would stick with Tam, if it's sealed and dry the motorhome is miles better than it was, start pulling it apart trying to make it like it came out the factory is uneconomical, :wink: it's an old motorhome and not got to be with him forever. :rofl:
He does a good job, unlike our self build neighbour last night, he has put his rooflights on back for front and 3 solar panels that I wouldn't trust over 30mph. :Eeek: Bob.

I've seen a few folk doing that with skylights ...it seems deliberate but I have to ask if they realise they aren't designed for that and will likely fail over time

The two react with each other and the aluminium corrodes
mmhh!!

in 1991/3 I built a show winning car, it was fibreglass and aluminium construction and every nut bolt and washer were stainless steel on the bodywork attaching the aluminium panels to their appropriate fixings.

30 years later the car is still as it was the day I finished it and looks brand new with no signs of any corrosion anywhere.

Sorry Tam for any thread derailment 😉

Yep if it was easy to remove them and seal under I would, but the ones on the roof the screws were rotten. But the trim was still soundly fixed. So I opted to leave well alone for now.

The side rail is screwed in to the aluminium body which does have wood behind some parts of it. That wood was rotten and has been removed.
You've to remember this is a 25 year old van and some parts are completely inaccessible without removing the whole side panel. Something I don't have the skill or tools etc to do. So I'm just doing the best option I can in the hope it seals it up.

Getting plenty rain at the minute so it's getting well tested 😕.

Normal steel reacts with aluminum too unfortunately there's not a lot you can do about it. Usually sealant keeps the 2 apart till that fails. Where the rotten wood has been on this van you can see where the aluminum is starting to corrode. I have a series of little pin holes along one section which I can do nothing about other than a smear of sealer along inside before I bond the new wood too it.

It's a can of worms on these old vans and something I would have avoided had I been aware of the damp problem.
 
Flipping weather today is biblical, never seen rain like this since Ireland last year. Still waiting on the buyer for the euramobil arriving. I've moved the mobilvetta to my sisters for the day as I don't want it here when he comes to collect the euramobil. Just too much of a distraction etc and the guy can talk for Scotland. I ran a bead of sealer round that join this morning during a brief break in the weather so I'm hoping it's keeping this weather out.

I'll be happier once the big van has been paid for and gone it's been a long month waiting
 
Our Lenny Lenny HB will tell you off for that if they go into aluminum :rofl:
Yes an excellant way of starting corrosion.

Tam I know u are doing your best - not suggesting otherwise for 1 minute.
Modern sealers/mastic etc you get nowadays are so much better than they used to be.
Just seems a pity that all the hard work your putting in and replacing the interior paneling around that area which my leak again if you are unlucky.

Yeah I know ..but that said I'll be checking the seals I put round stuff every so often and redoing as and when necessary all these sealants are only ever meant to last 5 to 10 years before they start to crack or shrink etc so really everyone with a van over that age should be checking or resealing windows and skylights anyway.

I'll be giving this a good hose test before I repanel that area so I can see if any more leaks
 
So what type of screws are best then through aluminium?
Plated steel will rust but won't set off corrosion as much with the aluminium.
Stainless steel self tappers with set off galvalitic corrosion and the aluminium just gets eaten away around the screw.
You can reduce the effict buy using a sealant on the screw but with a self tapper there will always be a point off contact.

Much less of a problem when using nuts and bolts as you can put a barrier on the mating surfaces.

it hasn’t happened to mine in 30 years 😉👍

Have you taken the screws out to see?
Also far worse in sea air we live 200 yds from the beach and having spent years sailing and seen the results it does happen.
I cringe when people attach solar panels with SS seft tappers a recipe for disaster.
 
If the aluminium is anodised which most is on motorhomes etc you will be okay using stainless steel fittings.
Only on surface contact like head to panel. A self strapper will be biting into raw aluminium & the hole will just corrode away.
