Thread: Series Firewall Vent Covers

One I have are aluminium frame but steel wire - still very delicate. I manually wirebrushed them using a fairly soft bronze wire brush, but did not attempt to try and remove all the rust from the mesh, then a light coat of etch primer followed by black.

if they are aluminium, then get some spray on cleaner for ali car mags, spray it on let it sit then hose off.

They look reasonably clean except for the item bottom right of frame, in the past I have just grit blasted mine using Illmenite and have had no issues with that, anyway cheers Dennis

if you are only using a small sand blaster they should be fine but as JDNSW said I would wire brush them first to see what the outcome is then
