Cavity wax spraying?

[slybunda]

Looking to do cavity wax in the cars sills and box sections and doors etc now the aerosol cans if waxoyl and equivalent do seem to work out expensive compared to air compressor fed stuff so the question is
Would a small 24L 9cfm air compressor be enough to do the job?
Always wanted an air compressor but don't have the space in the shed for big one

I thought this was another mortuary thread. Can't advise what kind of compressor you need because I have that sort of thing done where I don't have to deal with the mess but it's certainly a worthwhile endeavor in a moist climate. For small areas I use canned wax made by 3M or similar products.

Yea canned aerosol stuff looks like the simple solution here too, was just wondering about air compressor since my kid would like to paint toy car models with it too so could get double use out of it.

I have a 1/5 hp compressor for airbrush. It's fine for thin paint. I think you need a much more powerful compressor to spray cavity wax. I think you need a compressor with >1 hp.

I use a "standard" 2hp tank compressor for fluid film and it barely keeps up. I'm under my car on a creeper finding places to blast, blast for a few seconds, then move on. Typical duty cycle. Make room for the compressor, they have vertical models if space is tight.

Maybe a dumb question, but how about just using Fluid Film in spray cans?

Not sure I can get fluid film here in the UK.
Can get stuff like waxoyl, dinitrol, hamber s50 dynax and noxudol 700/750

Had my cavity sprayed with wax by my proctologist in the late 90's and no polyps since. The stuff works!

Noxudol 700 has a spray can with a long want, for cavities there is nothing better according to a long time test done by classic car site.

Cosmolene?

The crayon stuff VW uses works great. I’ve never had a VW that developed even a speck of rust.

I used a small dewalt vane compressor in a pinch, cranked it up and it worked fine.

When I went to a shop to have them do CarWell spraying they used a long want, maybe 2'. Or 30". They drilled holes in the door sills and used the wand. Also took off tail lights and used the wand. But they also had the experience to know where to drill the holes.

Wax is OK but the oli based rust prevention products "creep". So if a rock scratches off some of the product the nearby product will creep to cover over the scratch.

I think NH Coating only suggests their wax product for new cars.

Need to be sure the wax does not plug up any drain holes in doors, etc.

Another guy pushes his sprayer up the drain holes as he does not want to drill holes.

Yes I can get this stuff here there is a noxudol 700 and a 750 version which is better?

 

[Trav]

The 700 is the one I use and nothing has rusted on anything internal I used it on over the last 10 years and it is solvent free. IIRC the 750 uses solvents so I never used it, I don't like the idea of solvents out gassing into the cars interior.

 

[slybunda]

The noxudol 700 comes in schutz 1L bottles, can these be sprayed with those Venturi types sprayers with the flexible 2ft hose? Would it spray properly with a small 24L air compressor?

 

[Trav]

Sorry I have no idea, a 6 gal compressor is pretty small so I have doubts about that working very well. I was thinking about this with the 24" wand. I am sure in the UK someone is selling this setup.

it will spray ok you might have to pause often depending on the type of sprayer.

The Fluid film sprayer recommends 80-100psi and consumes 6-8cfm.
(check recommendations of the actual sprayer you are purchasing)
so what is your compressor stats? 9cfm@what psi?
a 150psi 6gal will do alot better than a 125psi 6gal as far as reserve air@greater than 80psi.

I don’t know if they have Mike Sanders in the United States, but this stuff is popular with some here in Germany. I once had a Lada Niva that I treated with Mike Sanders wax - sprayed in body cavities and undercarriage. You have to heat it (liquify) before you can spray it, but once sprayed on it sticks pretty well.

I don't have a compressor yet but looking to get one. Space is an issue for me so the smaller the better. From the room I have left in the shed a 24L compressor will fit and possibly a 50L but need to get it's measurements before committing.
I was looking at something like this:

Which seems to be compact enough. Will be enough for cavity wax spraying though is the question
