Cavity Wax, Best Way

[bricol]

The long thin lance with the pressurised guns allows you to shove it up a hole in the end of a chassis leg, sill, door/screen pillar, internals of boot lids, bonnets, hatches etc right to the other end, pull the trigger and pull it back at a nice constant speed.

A quick test beforehand in an old 2 litre bottle will show the coverage and a suitable speed.

The little metal lance thingie allows underbody wax to be easily applied. Found mine very useful over the years.

ive heard you can spray your shed with old engine oil in minutes too

I bought the Sealey pressure pot to use with a 5l tub of Dynax S50 for internal sills etc.

Still not got round to it but on the list before winter sets in..

Yes, the SG18.

I thin my undercoating recipe with "white gas" aka coleman fuel, so that I can fog it in internal cavities.

What else do you use ein your recipe?

Your mention of fogging is some of the reason I wondered if these 'spray guns' may be better than aerosol as they potentially atomise the product better for fuller coverage.

I use a standard compressed air suction gun, sometimes a sandlbaster gun.
1 part fluid film
1 part cosmolene
thin as needed.
I get minimal drip off, the white gas evaporates pretty fast.
The cosmolene skins over like pudding, but the fluid film stays wet (to keep creeping) underneath.
As it get's a skin quickly, it doesn't pick up dirt so badly.

I'm on the fence with ACF-50, would definitely be a lot easier than using Dynax S50 but will it hang around as long?.

 

[steveo3002]

claims to last a year or so ? although i dont see why it wont still be around longer than that in a cavity

i guess the blurb suggesting its used on airplanes etc suckered me in , you dont want your cesna wing falling off due to rot eh

 

[PhillipM]

It's generally used for laying up aircraft over winter in a nice protected hanger or under a tarp though...

You don't see Wichita spam cans driving on salted roads either......

 

[steveo3002]

yeah gotta try though eh ? it seems alright to me for protected areas , its not gonna wash off inside my quarter panels anytime soon and it smells nice /minimal mess , not convinced about external use in the uk although we have a member on here that swears by it

trouble with all these hardly any of us are starting with a new rust free car , and you really need to stick to one product and be able to come back in 15-20 years and show how its held up

Shoved dinotrol inside my car 15 yrs ago . . .9 yrs ago after replacing rusty metal, shoved Noxudol 700 inside it . . . so far, shoving a camera inside the sills shows good protection ..

I have always used either Dinitrol or Dynax cavity wax aerosols, but wonder if using a special spray gun will give much better coverage. Because it's in cavities it isn't the easiest thing to tell how well it's going on, so using what's accepted as the best way is all you can really do.

Does anyone use one of these, I have seen them sold be various companies range from £35 upto this, and they all look identical.

Are these one of the better guns/ways to apply the wax or are there better (home use) guns?

Thanks

I've always used this pressure gun. I heat it in a bowl of hot water yo get better spray. I use the thick honey dinitrol.

 

[Ianb]

I have only used the aerosol version, but Dinitrol ML seems great for cavities, seams etc, it is so thin and runny.

 

[Keithmac]

@steveo3002 that wasn't a dig by the way, just genuinely interested how it lasts long-term.

The Dynax S50 definitely give a good coating.
