For protecting bare metal (after welding/rust removing etc.) which is best: Red Oxide primer or Hammerite?

I have used both in the past but I just wondered which was best for long term protection.

Opinions folks??

zinc rich red oxide primer is my fave (also used on offshore oil platforms..)

My preference is for Hammerite (copiously applied) followed by
Waxoyl.

I'm with Ray,

Red oxide primer everytime.
Maybe a rust remedy first if the metal is lightly rusted.

Hammerite, apart from being expensive, always seems to chip off after a short time, no matter how good the surface underneath.

Red oxide every time. Hammerite doesn't protect properly unless you use a primer under it anyway.

red oxide anyday.

red oxide or zinc oxide paint. never liked Hammerite.

Or POR15, if the surface is a bit dodgy - thats magic stuff, but you need to top coat it, as it degrades in sun light!!

Hi Folks,

I usually thin some red oxide or zinc 182 down with cellulose thinners and lash it on so its wicks into all the small crevices you don't see. Then a coat of normal red oxide/ zinc 182. Have found Hammerite good for areas that don't get stone chips, etc as it is a bit too hard to take stone chips.

POR 15 (from Frost auto supplies) is great for under the car. Have used in the past on the difficult to protect spots that get all the stones and spray with fantastic results. Not cheap, and not too environmentally friendly either, but you'll only have to do it once.

im hoping to have new sill area on splitty by the weekend , im going to red oxide then hammerite the underneath, is it best to remove the black primer on the new panels first or paint over it? ,cheers stve

Right, well, on a similar theme, what is the opinion on the best treatment for bare metal on parts that are going to be painted body colour?? (engine bay, etc). Presumably some sort of etch primer. Can this be bought in cans to protect as you go along? or do you have to bare a complete area then spray with a compressor?

I used zinc primer on my MG but on hidden areas to be covered in waxoyl later on. I think this has an 'etch' in it but I just wondered if this was OK to use or if there was a better product out there in cans? and if it's OK to use a high-build primer on top of the zinc primer?

Presumably some sort of etch primer.

Yes
Yes
You don't have to use a compressor + spraygun and do the whole area but it gives better results than spraycans - the stuff i sprayed with a gun was much nicer than the spraycans I have now. However it did give me a very sore throat

Well it was just to protect it while I'm doing the job. It can be flatted and sprayed properly after or imperfections hidden with a high build primer. I just don't want any nice shiney bare metal surface to end up looking like the hull of the Titanic while I am exposing the rest of the car to Mother nature's ravages.......

You don't have to use a compressor + spraygun and do the whole area but it gives better results than spraycans

Yes I know, but if you buy the stuff at a paint factors in a paint can, you either have to apply it with a compressor/gun or try to get it put into aerosols.....

I know etch primer is available, just was not sure if it was available in aerosol tins.

my local paint factor does it in spray cans so I guess most will

end up looking like the hull of the Titanic while I am exposing the rest of the car

Well the pictures I saw of the hull recently did not look to bad after all this time although I can understand your reluctance to go for a Limpet finish

well ive made some progress this week , finished metal treated to wire wheel on drill , jenolite,redoxide and then hammerite, hopefully thatll do it,steve

I thought you could not paint Hammerite over red oxide? Don't you need to paint Hammerite over bare metal or Hammerite primer?

Any pics of the resto by the way Steve?

Can this be bought in cans

You can get it in halfauds - its a u-pol product I think in a shiny green/blue aerosol can...

ill find out about painting cheers cam, hope to have photos online soon , need to see my pc wizard mate
