Rust prevention

[Pastry]

someone should really sticky a sill guide as its asked about twice a month. [] dynax s50 comes with a flexible lance and a diffuser tip. you can spray from the panel in the door frame or the bungs under the carpet (inner sill) or feed it through drain holes. you can remove the diffuser tip with pliers for a more direct spray and to get into the tight bits in front of the rear arch. Make sure the drain holes dont get blocked in the process. an LED torch helps or you can use the LED flash off a mobile phone. mobile is also handy for taking photos. in my experience other rust spots are around the rear number plate lights, underneath the rear hatch seal, around the windscren seal and under the main rear lights. I had some rust spots from a poorly fitted number plate. ive also heard the rear arch wells in the boot can rust. my present concern is under the front wings but haven't got round to taking them off for a proper look. edit; s2/turbo owners seem to get the bottoms of the front wings rotting.

If I were you and spot rust areas that you can access like the rear of the wheel arches you might want to nip the rust in the bud if its not too bad (before bodyshop work is needed) . To do this you need to take the rusted area back to bare metal with a dremmel tool or similar, paint with a rust eater like Bilt Hambers Hydrate 80 then top with a hard paint and finish with a underseal or stoneguard depending on the location of the rust patch. Your probably never going to stop rust 100% but the idea is to slow it down considerably and not let it go on unchecked. Then you should avoid nasty surprises when you find you've left it too late. But it looks like your doing the right thing by dealing with it now. If you cant access the rusty area (like inside the inner sills) then application of a good wax like Dynax S50 should again slow the rust process down... Edd

Hi,

All this rusty sill business im reading has got me paranoid. Bought some tectyl ml and was going to spray into areas.. mainly sills.. and any other areas people might recommend that rust ? What is the best way of doing this to reach the entire length of sill ? I was reading also about drainage holes so dont want to block them. Any advice on where and how to spray this stuff would be useful

Thanks.

I bought a can of Dynax Underbody wax protection and sprayed underneath the sills too. There was some surface corrosion around the jacking points and towards the back, near the wheel arches. I cleaned it all up really well then applied the underbody wax. I too used the Tectyl ML in my sill cavities - it's very good stuff. Make sure when you spray it into your sills, you have a few layers of newspaper on the floor to catch any that runs out of the drain holes, if you're doing the job in your garage. It's rather runny, so you should find that it doesn't block drain holes. I'm starting to wonder if it is worth taking the vent covers off the doors and spraying some in the cavity there. I haven't heard that is an area vulnerable to rusting though? I'm also thinking of spraying some into the windscreen frame, underneath the rubbers. Have a look to see if there's any corrosion around the fuse box or the area on the opposite side, as rainwater filtered down through this area and if one of the drains is blocked, it can create a bit of a lake!
