Zinc Spray: best anti rust spray

[Maxwell-8 4,277]

I watch quit a lot of youtube, channels like Kevin Alberts, Ebinmain  . but surely other big channels, But I never see anybody using Zinc spray, do you guys have this in the US.

I use it all the time, and it's the best product against rust that we can get here by a long shot. It's spraying a thick layer of zinc, sometimes it has alloy in it too. Galvanizing with a can. never ever have rust seen coming true, and i don't always sand properly. It's also very scratch resistance. 

 

I always paint the inside of my rims with this stuff.

I've seen it in the past as some sort of welding spray. 

 

We don't use it as a primer because it's expensive. (minimum $10/can for cheap stuff, $30 and up too)

 

I can buy a lot of Rust-Oleum 2X primer or just use the paint.

We do use it after welding,even though its not related to painting. We also use on stuff that has got to be buried, like gatepoles, cause it digs in the metal, keeping in rust free, in the hardest conditions. And it doesn't chip off, like paint could

 

Paint, we pay €20 a can, and this zinc spray is "only" 14€

Back in the 1970's I worked for Chrysler chemical and we made paints and sealers for all the Chrysler cars and trucks.  We also made a zinc rich primer that some guys would spray under there new trucks. It works really good. Its a shame that they didn't spray it on all there cars and trucks. No one wants there cars and trucks to last forever especially auto manufacturers

Except Wheel Horses manufacturers! hihihi

 

I have seen new Mercedes's rust  in 4 years, brand new paint can be scratch off with a fingernail.

 

Whit zinc and such, manufacteurers could make a car last for ever, but it's just not good for the economy i guess

I used a zinc rich spot weld through primer back in the 70s-80s but it was used between panels and I wasn't around decades later to see if it did help.  Hope so.  I've used zinc rich "Cold Galvanizing" over galvanized panels that I've welded hoping that it would last like the galvanizing that wasn't burned off but I've not been impressed at all.

 

I have NOT used the product of this topic, Alu-Zinc Spray, but I'd certainly try it if I could find it here in the States.

We used a lot of spray galvanizing brand name Zink It worked well for us in electrical substation construction for coating Unistrut when cutting or grinding. 

[DennisThornton 4,769]

There's many with some being up to 93% zinc but I've not had much success with the ones I've used.

My body shop guy was just talking about this the other day: said he wished he could still get zinc chromate. That sounds like something our illustrious leaders took off the shelves because it’s too scary for us to have ha.

Quick Google shows it's still sold.  Wonder why he can't get it?

State regs?

[Greentored 3,216]

Just asked him. Yes its still available, but it is not the same formula as the 'old stuff'.  Kinda like todays 'aircraft paint stripper'. The government took all the 'evil' out of it. Does it work? Yep, but not even close to the original stuff.

I remember spraying this stuff called 'variprime' in the body shop back in the 90s. Sure, we'd dust a fender or a quarter out in the shop with no masks, hey it was almost 3 decades ago and we were young and dumb If it was in the air, you would be coughing by the time you took your second breath, period. NASTY stuff, but it worked!

Dupont. I sold it. Maybe the best etching primer of its time...

Yes sir it was awesome stuff. So was Imron.  And you had BETTER wear an appropriate mask when spraying either one!

I used zinc chromate primers in my shop and felt good about it but alas I don't know how well they worked.

Used allot of "red lead" in the Navy back in the day.

I use the spray “zinc” coating bought from “screwfix”, a store in the UK that sells building supplies etc.This particular one has an almost chrome like sheen when first applied. The wheels and wheel weights on my C121 were sprayed with this as a  quick “touch up” before a show 3 - 4 years ago, no sanding or any prep other than a wash down.They still look ok!

one friend dad owned a body shop - he often used imron and I believe he also used variprime 

 

at the time he rarely used a good mask / respirator - but the exception was when he sprayed imron

 

before / after pics below of my friend's 68 Chevelle SS sprayed with imron metallic black 

 

( my friend got this car for around $200 ... those were the days )

That entire car could rot away and the Imron would still be there and perfect haha!

Yeah, they salted so heavily in NJ, we could get rust buckets so cheap in the later 70s and they were only a few years old. Drivetrain tight...  Just another reason to head south and now they're using salt spray down here - just can't escape it. My '80 Olds had a special coating behind the rear tires. That high rust area survived - as well as the rest of the car - and I put 210K miles on it. Our family '70 Impala was well vented behind all four tires in only 4 years.

[tom2p 2,394]

the 68 Chevelle SS in the above pic was originally from Oklahoma (or near)  - super clean - all body panels were rust free and the frame / underside was almost void of surface rust 

few years later I got a 69 442 that was also originally from Oklahoma ... same price - around $200

 

similar condition - very clean - although this car did have a few small issues as well as some surface rust on the top of the body panels where the sun beat through areas of the paint

What did the part look like before any treatment?  Was it shiny and new?

 

The rust converter I've used needs to be topcoated.

 

In fact I believe the zinc should be also.

 

Try the test in vinegar!

 

Can you get POR-15 in Belgium? "I put that 5h1t on everything!" (not really, it's too expensive for that, but it's quite amazing stuff!)
