just been sanding some parts of my car back to bare metal and i can now feel a few spots of rain in the air.

is there anything i can coat it with to stop it from rusting agian?

 

You can just put a coat of primer over it for now

 

if you mean a temporary fix until the rain passes wd40 grease or vasaline otherwise id use (cant remember the exact name) oxide primer

 

its not ready for primer. i've just coated it all in WD40. do you think the rain will wash it away?

 

I know its not ready for primer but I used to just put a thin layer on to protect that would take 5 mins to smooth off again

 

whats the area???


cover with a grease , then just wipe off and degrease when need to go back to it, or as Poom says, give it a slight cover with primer, use a red oxide tho, but primer is absorbant, so dont leave it to long

 

the area is half a sill, little bits on the wheel arch and an area just behind the wheel arch on the underside.

WD40 will just wash straight back off will it?

to be fair, i suppose it doesn't make much difference as it didn't take me long to get it to bare metal as i used a wire brush attachment on my angle grinder
