hey guys i have a rare 2 door sedan (rare for australia) and it had a bit of THICK surface rust on the roof when i paint striped it. although it hasnt gone to far there is alot i was going to get it paint striped but there is a 8 month wait. is there a manual type rust eater? does it eat it how does it work b4 i apply primer?

POR-15

Go here...
Eastwood

I've tried POR-15 and it works good. Love their metal preparation system. I've used Rust Bullet but it doesn't come in black. I lean toward the Eastwood online store because it has anything and everything you need for bodywork. I believe everything you can do to superbly prepare the vehicle the better the outcome will be. It's just more work on your part. That's the tradeoff.

So you have used POR15 and Eastwood - how do they compare?

I thinking of using some POR15 on my sons very surface rusty Torana soon - but have recently heard about KBS Coatings and Eastwood as competitors.

I plan to brush it on, then prime, then brush on Brightside.

What do the experts on here think? POR15, KBS, Eastwood, or sand it to bare metal and etch prime...

i just piked up this stuff from the paintshop and it says to wet the rusted area first with clean water, wipe over with rust stuff then once dry wipe it of with a dry rag. is this all i have to do. surley this alone wont cure my surface rust problem will it?

I don't believe in any of those "rust converters"

To remove the rust you need to hit it with a wire wheel on a grinder, or a similar rust removing wheel - whether it be a flapper wheel or disc or one of those fibre discs that look like a giant gasket remover.

Good old fish oil is a good next step. Its highly penetrative, very corrosion resistant and dries to a film you can paint over.

I like to use a kill rust type initial primer over areas that had rust, just make sure its sprayable. Then seal that with a normal automotive primer.

I had surface rust on the roof of my ute.
I got it sandbasted - It's about as clean as you can get then.
Don't take any short cuts (I am not saying anyone's advice is a short cut)
Because once the top coats are on, they're on.
the last thing you want is your fresh paint job to start lifting etc.

Hmm...I'd heard some sucess stories with the POR15, KBS Coatings, Eastwoods - so thought it would be OK.

A panel beater friend of mine said rust converters were pretty crap too, I just want to believe their good so I don't have to pay $1000+ to get the whole car sandblasted.

Just get the part(s) as clean as you can with wire wheel then scuff it a little with sander and then coat it with a rust inhibitor like the POR-15, Rust Bullet, or Eastwood Rust Encapsulator. It makes for a good base coat and seals the rust longer than anything else.

i think the POR15 would be good in Austraila - as they have a tie coat primer that is a hi build sandable primer.
