W123 hood pocket rust protect/prevent
Hi,
My 240d is pristine, but in the d/s hood hinge pocket, I just noticed that one spot has lost the seam sealer and paint, so there is metal exposed and a seam is visible. There is slight surface rust, but no metal flaking. Need to know the best way to repair and then protect these sensitive areas. My thought is one of the aqueous rust chelator/converters to take care of the surface rust, then seam sealer, Eastwood rust encapsulator paint as an overall coverage, then the correct color paint to hide completely. Does that make sense? I think I'll brush the coatings on, because aerosol will go everywhere... After all clean, anyone have a reason why not to use a waxy coating in the hood pockets to protect overall from rust? Thanks!

Topcoating after using rust reversers (very difficult) and waxes (usually impossible) to adhere to those materials is hard. So hard in fact that I do not know how to do it to where I would be satified with the result.
Anyone more experienced with these materials have any advice? Brushed on coatings usually have poor appearance. You may want to skip the topcoat.

Thanks! I'm not concerned about look inside of a hood pocket, which is OE painted over seam sealer. I'm most concerned about protection for the long term.
Interesting that paint will not adhere to chelates or converted rust to metal. Even with an etching primer, perhaps? Thanks for the insight!

On my 82, when the maple trees started dropping their little seed things, my car was sitting for a week or two. Enough dropped in to clog the hood hinge pocket drain, and water collected.
No leaks, no rust, but I noticed that the paint seemed to feel softer as did the seam sealer. I suppose water will solve these paints if sitting long enough? So I need to seal somehow, look good, look bad... Need to clean out and fully seal up with wax or something else. Hopefully if I put the hood full up, undo the hinge from the pocket, fold it out of the way, remove the spring, and then...? Should I powerwash? Soap and water? something else? Im tempted to spray some oily creeping stuff in versus something that "hardens", but theat will make a mess when it rains. So I dont know what to do... thoughts???

Use some naval jelly to dissolve as much if the rust as possible then apply some POR15 per the instructions.
