Buggyjam Posted February 15, 2018 Share Posted February 15, 2018 Just exploring the inner arches on my car at the front. There’s a few areas of surface rust here and there on the inner arches. A couple of circle spots where the spot welds are that I suspect are more than surface. Some areas are still yellow paint but a lot looks like bare galvanised whet paint has come off. I suspect the surface rust is where the galvanised has failed or taken stone abrasion. The fact the paint is missing in quite large areas near the suspension mounts tells me looks like the paint has been stoned off over time. Doesn’t look like there was ever any waxy underseal applied at the factory (looked at a 981 at the opc and it had it) just paint. I’ve got a stack of Bilt Hamber stuff sitting and waiting and going to attack it all. Heres the workflow I’m planning:- Jack each side up and do the following 1/ Inner arches removed 2/ degrease using Bilt Hamber surfex 3/sand areas off using course grit. 4/ use Bilt Hamber Deox C gel for 24 hours under cling film 5/ scrub, rinse with water then paper dry and use misses hair dryer to make sure water gone 6/ apply two coats of Bilt Hamber Electorox zinc primer, leave for 96 hours for full cure 7/ Apply Bilthamber Epoxy mastic anti corrosion coating leave to cure for a day or two 8/ top coat with speed yellow using a brush (its out of sight up under arches) hoping that sorts it. Big prob is need temperature over 10 degrees for some of it to cure. anyone else noticed any rust at all on their inner arches? Link to comment Share on other sites More sharing options...
