Can I treat slightly rusted coil springs with Waxoyl

[jimmylau8080]

Dear All

I saw my coil springs are slightly rusted? Should I wire brush and apply Waxoyl Rustproofing Aerosol or just not bother

I tried Waxoyl Rustproofing Aerosol before it looks like a thick waxy. If I applied that, will it mislead the MOT tester. He might think that thick waxy is like oil leaking?

Thanks

May I know what type of oil I should use?
