carpet was all stuffed up from dad's wet golf clubs , which led to rust so carpet was gone. rust left to build up in boot dont flame my method bcoz i'm a newb and dont kno how to do things 1. got a buffer and buffed away all the surface rust i could 2. went at the hard bits with a screwdriver 3. cleaned up boot, bought rust killer 4. shook bottle, and applied it to the rust (turns black when chemical reaction occurs) 5. left to dry over night 6. primed the boot, left to dry over 2 days 7. painted the boot with black paint 8. waiting to get carpet for the boot. Some original photos have not been recovered yet.

yep, spot on mate, thats exactly the method that i have lined up to do this weekend but did u use a good brand paint??? im using the killrust system by wattyl, the black paint has an apoxy in it to give it more strength. Some original photos have not been recovered yet.

same method i used man. works well but cause the boot still leaks a bit. i lave the plugs in the boot out, gets a bit more dust in there, but the water drains freely, not that there is much. Some original photos have not been recovered yet.

i did the same but for the battery holder. I found using a drill with a grinder on it works really well for getting rid of the majority of rust.

check for rust around your boot seal.... youll be supprised how much water gets held in there and is free to rust away the lip to hold the seal on!

yup - silicon is evil - it attracts water so it won't prevent further rusting

yea true that, i dont deny that, but if ya treat and clean the rust first and then properly seal it with silocone so the water cant get in then it works sweet.

seriously - do the job properly.. have the rust removed and fix the holes that may have occurred with new panels or welding - even fibreglass, then respray... please don't use silicone... only use that on a crap car or a very temporary fix if you cannot afford at that point in time (ie when we had a $100 Corolla we used lots a silicon - but it'll never touch any of our holdens! LOL)

i have rust bascially all the way under my boot seal, its rusted away so much that it doesnt hold the seal up , instead it holds it so its horizontal and the water just pours into the boot how much do u guys think this would cost to be fixed professionlly,

Find a wreck with a decent boot at pick-a-part or some place similar, chuck it over the fence, then walk out...

yeah silicone with the chemical formula of SiO2 doesnt become 'acidic' and eat away at the metal....the 2 oxygen molecules that form the silicone compound undertake an oxidative chemical reaction that eats away the metal *thinks back to yr 12 chemistry*

I had a similar problem with the Boot Seal, the Metal Lip that holds the Seal on was rusted, almost gone around the corners of the top of the Boot and in a few other areas. If the actual lip has completely rusted off in various places, unless you're good with a Welder and an Angle Grinder, I would say get someone else to do it, it would be worth it. With mine, I removed all the rust, used Rust Converter on all the rusted metal, cut pieces of metal to replace the bits of the Lip that were missing, used Body Filler to hold it all into place and then sprayed it with a good primer and 2 Topcoats, bought new Seal Rubber for around $30, and now it works perfectly. 8) I didn't have to Weld my pieces of metal onto the Lip, as there were basically only holes there, so Body Filler was enough to hold it all on. If there are major sections that have completely rusted, then it would be the same procedure with just bigger pieces of metal and the need for it to be welded on and then grinded later to smooth it all off. Trust me, its not a nice job to do in any case... Some original photos have not been recovered yet.

before i had the rust out of my sills i siliconed my seal in properly and haven't had a problem since. Simple; - removed the seal - wire brush and ranex rustbuster all round - screwdriver to scrape rust out of seal - fill the groove with silicone sealant (the one designed for metal gutters, etc) - fitted the seal and squirted thick silicone onto the surrounding (cleaned) area. where the metal lip was eaten away just add more. after its smoothed, let it dry properly and use touch up paint to paint over. It isn't perfect, but the panel beater didn't even want to disturb it, he suggested just leave it cos it ain't going anywhere. the downside is if you LATER want it to be a show car and paint it properly, you'll get fish eyes in the paint from the absorbed silicone.
