there is a few rust removers out there most are some form of weak acid, it would penetrate all the seams and dissolve the rust, question is what else would it attack?

I did have some stuff called ryd lime which reacted with rust. concrete and calcium and left most other things un touched and you just washed it off after.

shit.. they stuff i got is wattyl killrust metal primer... it says

A high quality, anti-corrosive primer which provides a tough, flexible, rust inhibiting coating to
protect steel surfaces and to provide enhanced protection and give a base for Wattyl Killrust
Superior Protection Epoxy Enamel, or other appropriate finishes. On aluminium and copper, prime
with Wattyl Killrust Super Etch. On galvanised iron use Wattyl Killrust Oil Based Galvanised Iron
Primer or Wattyl Killrust Super Etch

from what i can gather its just a extra strong prymer? so wont actuly do anything to the rust that is already preasint?

would some zink galv spray first help? or just cause the primer to peel?

I would say POR15 will be superior to the wattyl stuff, although the wattyl stuff would probably be ok on bare metal. I have a couple of cans of red oxide, but would go POR15 for bad rust areas over the wattyl. I haven't tried the wattyl stuff yet, but the por15 stuff I have used s still looking like new 2 years after application.

go to super cheap, or repco. buy one of those $30 sandblast kits and a $15 bucket of sand. go nuts then POR15 everything

$30 sandblast kit, what is this? Keen as unless you need the compressor too

[Dell'Orto]

Yeah you need a compressor as well

[Bling]

False advertising I got all excited too. Blardy rust

who sells por15??? cause its not realy posabail to get it back to beair metail in that seam ay...

[Bling]

www.por15.co.nz you can find local stockists on their site. Or you can buy direct from the site and pay postage.

I'd recommend a POR15 starter kit or super starter kit as you get all the stuff required to complete the job start to finish.

Just keep in mind it will only fix what it can get to, any hidden rust will still be there.

....POR15 is a rust inhibitor/converter.....

Not trying to be a dick or anything. Actually its not a converter. It works by sealing off the existing rust/metal from water and air.

Can you define converter then Adoom...

If you follow the instructions and use metal ready it dissolves the rust and etches the metal ready for POR15 paint. To me thats what I would call a conversion. Rusty metal --> etched rust free metal.

Just my 2c

# Removes rust by dissolving it...metal is left clean and ready to paint.
# Etches metal to provide a better surface profile for painting.
# Coats the metal with zinc phosphate to inhibit further rusting and promote better paint adhesion.

Keen to know if the sand blaster kits are decent or not?

Can get compressor no probs, so $30 for a kit would be good going

POR15 paint itself doesnt convert rust, it just covers it and stops it from spreading. Metal ready strips it off.

They're ok, nothing fantastic though, they're just a gun with a hose that goes into a bucket of sand. No idea what sort of life expectancy you'd get from one, though you can get replacement nozzles.
I used one to sandblast the a few patches on my bonnet, worked really well even with a piddly little 2hp compressor. Definately need a water trap though, otherwise they block up really quickly.

Yeah but who uses POR15 Rust Preventive Paint without metal ready? If a piece of metal to be painted is rusty its at least a 2 part process to use POR15.

I just considered using metal ready, the part of the system that converts rust, to be part of the job. I use it if theres rust or not due to its metal etching properties.


In regards to sandblasting Brad, did you just have to do it in small areas and wait for the comp to catch up?

[Dell'Orto]

Doesnt necessarily need metal ready, dont forget POR = Paint Over Rust

Yeah I just let the poor wee thing catch up, it was working really hard

From the POR15 data sheet on their website:
"...Use POR15 METAL READY to prepare surface before painting. Use of “rust converter” product is not recommended as they may affect bonding of POR15 to metal. POR15 likes to adhere to surfaces with a “tooth” rather than smooth,glossy surfaces..."

But we are really picking at .....whats the word?..Errrr.... being picky. POR15 is the only rust 'treatment' product I have ever used that has worked.

Just drive to mitre10 in te awamutu and get POR15 because it is awesome. You will only need the smallest tin cause it goes real far.

[79rolla]

haha... my dad stoped at miter10 te awamutu yesterday and they dont actuly stock it... apparently hey have had a cupple of other people ask for it aswell but they have never actuly stocked it...

Weird, por15 site says:

Rickits Mitre 10 55 Arawata Street (07) 871 5115

Is there more than one branch?

[soven]

Just order direct from the por15 site. Quick service and the guy who replied my email was helpful
