best way to paint slightly rusted vw body

[greggl4321]

What's the best way to paint a slightly rusty vw body? I'm looking for something that drys really hard and has the color beneath a bit of a clear coat,(or something like it)

With all of the talk on epoxys resins enamels acrylics ect it can get confusing.

What's the best way to paint a vw bug body to prevent rust?

Does rustoleum auto body clear coat prevent rust? Its not apart of their stop rust line ?

[vwkirb]

It does get confusing because there is not one answer. Nor is there on product that will do it all.

The answer depends on your constraints really.

Backyard, shop, drive way, paint booth, diy, pay someone?

I'm a backyardser slash DIY

Looking to stop rust. Not sure if the best thing to do is primer paint and clear coat. Not sure what I need, wanting to go with rustoleum products.

Not sure what goes on after the paint, or even which paint to use. For some reason urethanes are interesting me (is that what gives a thick clear coat)

Post some pics of what you have.

I'd suggest the Masterseries / Rustbullet type product as your first "layer" over any rust areas. On top of that and any other preped areas you can also use a DTM epoxy primer, or If you are going to with Rust-Oleum then their product.

I'd look away from Rust-Oleum, I'd look into an Acrylic Laquer. Neither will last like a polyurethane, but with any painting safety should be your number one concern.

You first need to address the rust before you just cover over it. I'd start by sanding the rust down to get it smooth, treat with phosphoric acid (Ospho or medal prep) to stop and encapsulate the rust, then a good primer like epoxy 2k or Master Series Sliver. Then you can body work and top coat with which ever product you want.

Phosphoric acid can be used to treat very thin rust or remove thicker rust. Rust bullet has a test where Cold Zinc Compound is 2nd to their product. I believe urethane's require more than just a face mask and ventilation to use so they are not within bounds for a DIY paint job. Correct me if I'm wrong on the last statement. There are a few water based auto paints in the U.S that has performance like urethane's but is not as common as Europe.

Right, I believe strongly the isocyanates in urethane are inappropriate to be used outside of a paint booth. They pose a risk not just for the user but anyone or anything in the area. 3m won't even suggest an appropriate filter for their cartridge respirators, they only suggest fresh air masks for use with isocyanates.

There's really not much out there with the performance of urethane. MCUs (Moisture Cure Urethane) like Masterseries, POR 15, or Rustbullet are a good bit less toxic when applied by brush, but still should be treated with respect.

Single stage Acrylic Enamel also uses a isocyanate based hardener.

Your really only based with Lacquers and Alkyds like Rustolium. There are waterborne paints like auto air colors but they need to be topped with a urethane clear. Unless I'm missing something, that's pretty much all the common options.

What about epoxy resin?

[vwkirb]

Sprayable Epoxy Coatings like a DTM Epoxy primer/surfacer/sealers?

They are a catalyzed product, but the chemistry is different than urethanes and a good respirator, a paint suit, and goggles are safe enough to spray it outside.

You really should research the particular product you intend on using. MSDS and TDS will tell you what you need to know.

I'm currently looking into finding a better solution to spray paint that does not hold up against salt exposure on painting parts or small areas. Zero Rust does not neutralize rust in my experience but does dry hard. I'm thinking of keeping some on hand and using it instead of rattle cans using a touchUp spray gun.

Here are the webpages for it if anyone is interested. They claim it is pretty safe.

Dtm ? I think that's it.
Looking for a epoxy that'll go on rust metal, perhaps think layers of existing paint.

Are there colored epoxy primers and then clearcoat epoxy clear coats?

Can epoxy clear coat go over rustoleum? Epoxy will get really really hard too won't it?

[Zundfolge1432]

So you want to paint over rust? This makes zero sense.

[greggl4321]

Why not? People likely can't always get it all. There are paints for it and I think they block the rust from getting oxygen and spreading. Won't any paint act as a rust encapsulator?

How come the rusteum paint job doesn't start off with a primer?

[theKbStockpiler]

Paint over rust products can only tolerate maybe .005" of surface rust so 99% of the rust has to be removed. In a dry environment painting over rust might last 3 or more years but if the car see's rain it will show rust much sooner.
From what I have read epoxies are more dangerous than urethanes

I suggest you get some professional training in paint and body. Nobody that knows anything paints over rust.
