Rechargeable aerosol cans

[JHZR2]

Hello,

Does anyone have one of these air-rechargeable aerosol cans? Something like the Eastwood Eastwood Rechargeable Aerosol Can? I think some paint spray units can be pre-charged with air versus having to be tethered to an air hose.

I think these may be useful for spraying something like fluid film onto car underbodies, though they seem to recommend an "undercoating gun". Anyone knowledgeable of the differences?

Thanks!

Are you spraying paint or bulk fluid film? There is a big difference. Fluid films AS (aerosol) product is thinner then the bulk NAS product partially due to the propellant which bubbles off. With an undercoat gun I need at least 60 psi when shooting fluid film for reasonable coverage. If the product is warm it requires less psi, mine was cold maybe 40F.

Id be spraying bulk as I emailed FF and they recommended their bulk product for undercoating. Didnt mention anything about the AS product.

They did tell me I could cut it (though not recommended) with vegetable oil to get the correct viscosity.

They told me that liquid A and AR were overkill and not necessary for undercoating apps.

now just looking for an easy way to do it, a little bit at a time especially for touchups and whatnot, as simply as possible.

My thought was that a rechargeable aerosol is portable and simple, makes it nice.

The eastwood sprayer says thin liquids I highly doubt FF will be thin enough without a considerable amount of mineral spirits which defeats the purpose of using bulk.

You can purchase the aerosol AS for reasonable cost in cases and they have a wand no for doors etc.

I have two concerns with that in that my main goal is undercoating over the OE PVC-based undercoat on 30yd cars for corosion protection. I worry about the solvents in the aerosol attacking that, even if the FF does not.

Second is having all that solvent and propellant around to breathe. I like the control and flexibility of a spray gun if something can be utilized to spray it.

OK, from the FF site:

I have a gallon of Fluid Film and want to thin it down. How can I do that?
The first recommendation is to thoroughly mix the product. Fluid Film is thixotropic, and will get heavier upon sitting. Achieving room temperature with the product will help as well. If a thinner version is wanted, start by mixing a small amount of vegetable oil to the product until the desired consistency is reached. It is not recommended that Fluid Film be used in a pump type sprayer even after thinning. Airless paint spraying equipment is what is recommended for proper application, applied at approximately 2000 PSI as a minimum.

Does Fluid Film dry out?
No. Fluid Film is a lanolin based product containing no solvents. It will not evaporate or dry from the surface. Fluid Film will leave a wet, non-drying film, that will provide long term corrosion protection on all metals and superior lubrication for all moving parts.

Will Fluid Film stop grass from sticking to my lawnmower?
Wet grass will stick to almost any surface. Applying Fluid Film will prevent any corrosion from occurring and ease in removal of grass build up.

Does Fluid Film protect all metals?
Fluid Film will protect all metals from oxidation and atmospheric corrosion, including steel, copper, lead, tin and zinc. It will stop chrome and brass from pitting and aluminum and magnesium from oxidizing.

What can I use to spray Fluid Film in its bulk form? Will a pump up sprayer work?
No. The most efficient way to apply Fluid Film in its bulk form is with the use of standard airless paint spraying equipment. Airless paint sprayers operate under high pressure, usually between 1500 - 3500 PSI, which atomize paint into tiny droplets, propelling them towards the desired equipment. We recommend a minimum of around 2000 PSI. Applied at a film thickness of 3 - 4 mil, this will cover approximately 250 sq. ft. per gallon. We also recommend a spray tip of between 515 -517 for best atomization.





So I know nothing about Airless Paint Spraying Equipment. Tell me about that... What do I/dont I want and how much am I going to spend to get something that works? Seems to me that Im moving away from eastwood and into the HD world going for that type of a device...

About the only thing that the rechargeable spray cans are good for is spraying penetrating oil. They're completely useless for painting- since you charge them with compressed air and not something (eg R-134a) that liquifies, you only get a few seconds before the pressure starts dropping too low to atomize paint very well.

Airless sprayers will pump very viscous fluids at high pressure to atomize them. They spray latex house paint with no thinning. It also applies/sprays/flows a lot of material compared to a spray can or automotive type HVLP spray gun.

A basic home improvement sprayer will probably get the job done for $250. That's not a heavy duty piece of equipment but probably fine for once a year use as long as you maintain it well.

To answer you question, NO, or at least on my rechargeable cans...
I was having issues with the product atomizing properly and after being stumped, I called support and they told me only low vis products will atomize correctly out of the cans I had.

I was using a fluid that was closer to 30wt.....

Fluid Film AS says they use CO2 as a propellant. It looks like the Fluid Film is very thick soda for a few seconds as it goes onto a surface. Their propellant doesn't smell, and doesn't have any side effects. I'd know, both cars got 4-5 cans of Fluid Film AS this fall.

A case of 12 aerosol cans was $96 shipped. Without an airless paint sprayer, it was reasonable enough for me.

FF including aerosol has no solvents so that is a non issue just propellent. I use the aerosol around my horses and I have sprayed my dog in the face with it when he showed to much interest in what I was doing, accidentally of course.

The NAS product is thick even after mixing think Palmers cocoa butter lotion. If you have a local retailer and they have the brush can you can open it up and see what I mean. If you go on Lawnsite or Plowsite they have given away allot of the aerosol cans to potential customers.

If you are determined to use the gallon size you can always brush it on just like paint otherwise I would use an undercoating gun. I use gallons and aerosol, I prefer the bulk gallons but the aerosol is allot handier.

Amazon has 11 3/4oz cans for $9.39 A gallon looks like it is about $40.

So it looks like you get ~4x the material by buying the gallon versus the aerosol.

wow - I have a air-rechargeable aerosol can still in the box - been in the garage for years. Never tried it. There is a small bag of spray nozzles that came with it. Probably different spray orifice or patterns. There is a big eagle on the can - that was my deciding factor back then for buying it - I know, that's not a good reason.

I've got that SAME can LOL! Oh, and it is worthless.

You are right about that!

Worthless? Now I want to take the can out of the box and set it up somewhere in the garage - maybe on the workbench, maybe on one of the stereo speakers - it's for looks, not use. It's like American Spirit. Well in that case I'll have to display it somewhere around the Harley.

Few years back I bought the wife a half helmet with the American flags and eagles flames around it. She won't use it - it's been in one of her display cases since - Novelty, sorta like the can I guess.
