AdamP 0 Posted August 29, 2007 Is there any reason why I cant just bolt in an ali plate onto the original rivnuts on the roof? All the jobs i've seen had had them riveted on. Adam Share this post Link to post Share on other sites
ashley peddle 3 Posted August 29, 2007 mine is bolted on Share this post Link to post Share on other sites
pugrallye 0 Posted August 29, 2007 you can... but you have to use anodised rivets and make sure the two bare metals dont touch otherwise you can end up with chemical corrosion... which is nasty Share this post Link to post Share on other sites
Baz 421 Posted August 29, 2007 'Electrolytic' Sure, dome head screws/bolts into the exixting rivnuts will do the trick, with a smear of silicone sealer between to seal. Share this post Link to post Share on other sites

I'll be painting my ali before it goes on so that shouldnt be a problem! Will go and get a big bag of suitably sized dome head bolts then Adam Share this post Link to post Share on other sites
ashley peddle 3 Posted August 30, 2007 mine aint anodised and i dont have any corrosion yet (about 12 months since i fitted it...) Share this post Link to post Share on other sites
Guest bigbore Posted September 16, 2007 mine aint anodised and i dont have any corrosion yet (about 12 months since i fitted it...) ive seen some right states when i use to build horse wagons , in the end are company use to put plastic between the steel and ally to stop it happening Share this post Link to post Share on other sites
swordfish210 20 Posted September 16, 2007 i just bonded mine on using PU sealant and i used 8 rivets when i put it on to locate it. When it was all fitted i put a strip of white silicone around it to help keep the water out. Share this post Link to post Share on other sites
Guest bigbore Posted September 17, 2007 i was thinking of removing the one off mine , how much weight does it save Share this post Link to post Share on other sites
Baz 421 Posted September 17, 2007 IIRC the whoile factory vacuum/sliding glass setup weigh's in at around 14kg's. Quite a hefty saving, and of course up high so lowers the CoG. Share this post Link to post Share on other sites
ashley peddle 3 Posted September 17, 2007 sunroof set up is 14kg's. ali plate (3mm) is about 2.3kg Share this post Link to post Share on other sites
swordfish210 20 Posted September 17, 2007 i weighed all of the junk that i took off of mine and i weighed the stuff that i put back on and all togeather i saved 14.5 kg's. Well worth it especially as all of that weight is nailed to the roof Share this post Link to post Share on other sites
ashley peddle 3 Posted September 17, 2007 yeah thats the important bit i missed - is that its about 12kg's off the weight, but also it lowers the center of gravity - which is always a good thing (i think ) Share this post Link to post Share on other sites

pugrallye 0 Posted September 21, 2007 For all those people saying 'it hasnt happened to me yet' even peugeot used anodised rivets to prevent this occuring look under rear 3/4 trim (parcel shelf supports) for example, yes electrolytic corrosion, commonly known as gauling Share this post Link to post Share on other sites
AdamP 0 Posted September 22, 2007 I made mine up on tuesday and will be painting it next week I'll be spaying it with a good coat of etching primer and a nice thick coat of matt black Share this post Link to post Share on other sites
