Red Oxide Primer
Is this a good idea to coat an engine bay in first before an overcoat in normal grey primer?? From what iv been told its a good base coat to use over rusty metal, obviously after the rust has been rubbed back as much as possible.
Is there any truth in this??

Not sure, only seen yellow acid etch and no it wont rust but it doesn't matter as long as you cover the primer with paint the moisture wont get at it whatever you use.

So out of the two acid etch primer is the better one, however both do a good job of sealing previoulsy slightly rusty bodywork??
which you then can coat in grey primer before a colour coat?

I got informed that Zinc primer can also be used.. is that right?
I thought etch primer was for other metals, such as aluminium?
My mate had to use it on a landrover before the other coats...

you can paint normal primer over bare metal, as long as your not leaving it over a period as it is pourus.....in other words cover it with the top coats asap....red oxide is better to paint bare metal if you dont intend top coating right away.

You wont stop rust with ANY paint mate. Once rust has started to eat away at metal it will carry on till it is removed. Either cut it out, or shot blast it.

I've found that life I needed.. It's HERE!!
or treat with repeated coats of jenolite and a grinder with a wire brush on if you havent access to shot blasting, zinc based primers arent great either. In this weather its also a bad idea to be spraying unless youve got somewhere heated to do it.
