Rust Prevention in a Can?

[Slugwerks]

I'm sure we have all seen the rust converters and encapsulators in a can. Here is one from eastwood incase you haven't:
Internal Frame Coating w/Spray Nozzle

I find myself thinking it might be a very good idea to coat the inner torsion tubes, inner rocker panels, as well as other enclosed areas with this product or one like it. The eastwood product does have a zink part, I'm no chemist so I can't say if the zink in the paint does anything, but I do know they use zink in the galvanizing process.

You guys have any thoughts, recommended alternatives, or advice on the best practices to prevent rust? I'm redoing this car (1969 911E) from the ground up, and I'd like to have the car last as long as possible, while still being able to drive it even if it happens to be raining.

Thanks

haha... you just got their email too?

I picked up a backpack chemical sprayer for like $12. I'm going to make an end on some long tubing. Feed the tubing into the car very similar to the video and crank up the pressure

While I replace most panels I'm using picklex20 on all the inside of the panels before they get welded in, and then I'll spray in some rust paint to protect the inner surfaces and welds.

thx for posting the comprehensive summary of the links

[merbesfield]

For internal body parts use Body Wax by Wurth. You can spary with their Mulit-Sprayer or rig up your own. This is what many of the high end shops use during restoration. The link below takes you to a demo on the multi-sprayer. Wurth sells the Body Wax.

Yeah I did get their email this morning.

I guess asking helped some because I hadn't seen picklex20 mentioned before. Maybe I missed it. Merbesfield thanks for the links. Any reason not to double up this stuff? IE hit it with the picklex20 then a layer of bodywax from wurth? Sorry being stuck on the east coast makes me very rust averse.

Thanks again,
Rich

the picklex20 will wash off if it comes in contact with water.... it's like a phosphate rust converter/primer for keeping metal from flash rusting, so it needs to be coated with something.

as sksystems says, PX or similar washes off with H2o. Good for indoors, comes right off outdoors. Trust, me I know. Body wax is permanent, so to speak. Meant for long term protection. PX is just short term while your are working.

Check our this Jaguar restoration shop. They are one of the best. Look at how they use the Body Wax for explanation.

Old post, but thought I'd mention it, since there's quite a few Albertan's on these boards. Eastwood can't ship any paint products to Alberta, Canada due to some new paint recycling regulations?????

I was going to try out this product, but they cancelled it from my order, and were pretty vague on the reasoning. Now on the website most paints have a warning that they can't be shipped to Alberta, Canada. I guess our province is being turned into Kalifornia

I did manage to get them to mail me one of the long spray nozzles, which has a pretty standard attachment, so I'm going to try putting it onto a locally purchased can of aerosol rust paint.

Anyone coat the inside of roll cage material? Or does it all burn off from the welding?

[pksystems]

I hooked up the nozzle from this to a can of tremclad rust paint to give it a test in the longitudinals. Much like they show on the website, it does a pretty good job misting out the end of the hose. After a couple seconds tho, the paint will come pouring out of seams, openings...etc. so you WILL make a mess if you use this.

It sounds like you need like 4-5 cans to do most cars, at $20+ each tho. Buy one, clean up the nozzle and reuse in cheaper rust paint cans.

Pictures?

[john walker's workshop]

cold galvanizing compound in a spray can. wurth alu-zinc for one. also called weld-through primer. you would have to get creative to coat inside the rockers.

[pksystems]

Doing inside rockers will be no prob. I've drilled extra holes on the inside of the car, which the tube fits through. After everything is welded shut I'll give it another shot of paint, and then put rubber plugs in the holes. The outer rockers have water drains along the bottom that the tube will fit through.

Not much to see in pictures.... it's got a thick coat of gloss white, everywhere. Hopefully it dries before it snows again (Summer has finally arrived) Now that I've checked it over, there's a couple places that could use a bit more paint.

That's the top of the torsion tube on bottom, and underside of the old lap belt on longitudinal (now under reinforcing plates for cage)
