Paint for under bonnet chassis

[paul_a]

Hi the powder coating on the under bonnet cross member on my chassis right next to the exhausts has started to lift and flake a little. I’ve lifted the flaky bits off and the steel underneath is really good and solid. I guess it’s the exhaust heat that’s caused the issue. My question is what’s the best thing to put on it? Would high temperature exhaust type paint be ok or good old Hammerite. It will need something before rust sets it.
Thanks Paul

It’s the square box section just behind the manifold, that the swirl pot fixes next to. looks like yours has been removed.i reckon I could wrap it in the same stuff you’ve used. Where did you get it from? I thought about white exhaust wrap but 1. It doesn’t look nice and 2. I read somewhere it can hold moisture, which could make things worse. Paint and your wrap could be the answer?

The manifold is about 20mm away from the cross member. I’m hoping it’s just the heat and poor coating. 🥴 The chassis in general is really good.

Good point. It’s not corroded I’ve wire brushed it and it’s really clean and rust free. It’s just the powder coat that’s flaked off. Can I ask what you treated it with. Thanks

Thanks for all the good advise. I really appreciate the help.

Looks tidy. Is the extra protection the self adhesive foil on a roll? How did you apply it?
