MasterBlaster and wax???

[Socalsteve]

Hi all,

Not sure if this is a stupid question or not, but I'll ask it anyway...:xyxthumbs:

Since the MasterBlaster uses such high heat and force, does it melt or burn off the wax that is applied to the surface of a car?

As always, thank you all in advance,

Steve

It's not HOT it's warm...nothing to worry about in any way

 

[Helltopay]

The heat is not that high, mostly just warm. Accordingly, I would say that it has no impact.

 

[Kamakaz1961]

Not an issue at all. I use the Sidekick and it blows warm air similar to the Blaster. I use wax as my LSP too.

I would not worry. You are fine.

•Need to find the temperature of the air flow generated by the MasterBlaster (MB).

-Carnauba Wax starts melting @ ~180 F
-Bee's Wax starts melting @ ~ 130 F

•MB's air velocity/force:
-Anything that "touches" the Wax, degrades the Wax to a certain degree.
-Compare the degradation of the Wax, as it's being pounded by the MB's forced air-flow, to the same atmospheric air-flow pounding the Wax covered vehicle while driving.
-The water being blown off the vehicle...as well as the focused air-flow from the MB...may also be a Wax degrading factor.


•I'll conclude that:
-Unless the MB's forced air-flow temperature exceeds 129 F, then this particular heat is not an extremely deleterious factor.
-The actual force of the air-flow, and the water being blown off the vehicle, may cause some degree of "harm" to the Wax.

-However harmful to the Wax the MB may/could be:
It's probably still better than using towels to dry the vehicle!!

-Wax is a sacrificial barrier:
Easily replaced. More so than ClearCoat paint.

I am sure that if you let your car under the Summer sun, it will get way hotter than when is being dried with the Master Blaster.

For those interested...something posted in the past. I have to believe just sitting in the sun causes more heating that the MB since it is localized and short termed. The entire paint is no continuously heated.

Equipment:

• 1 cooking thermometer and held it by the head and not the stem.
• 1 8 HP Metro Master Blaster

Ambient 78 F (matched another thermometer)

4HP Mode
Exhaust outlet - 118 F
End of hose - 120 F

8HP mode
exhaust outlet - 133 F
End of hose - 139 F

The exhaust port has a 1-in outlet, the hose it closer to 1/2-in so that may explain the temp rise but I was thinking there would be more heat loss in the hose. I guess the air is moving fast enough to not get cooled as much.

The air was uncomfortable to hold at on 8HP mode once temp stabilized. If I redo it, I will try some fixture to hold the thermometer. It takes over a minute for the temperatures to stabilize.

There goes the beeswax down the drain!!

I bet my black corvette gets way hotter than 135. Anyone know what temps Rejex and other sealants are good up to?

 

[allenk4]

Would a better measure of the impact of the heed air from a MB be an IR thermometer pointes at the surface of the paint?

Given how a MB is used; I can't imagine the panel ever gets close to the temperature at the nozzle


....or you could just put a thick layer of wax on a small section of your hood and blow the MB over it a few times to see if the wax is visually melting or evaporating. Would be an interesting experiment

Sealants/(synthetics) start melting/fracturing @ ~ 350° F.

Thanks!

so given the surface temperature of a black car can be hot enough to melt wax, how well do you think traditional waxes stand up to a black car sitting in the sun with no airflow? is any wax in direct sunlight after an hour pretty much toast?

ever tested? or does the wax somehow keep from flowing when it becomes such a thin layer at that point?

If the temperature of the panel exceeds the melting point of the Wax...then the Wax (which is a compound comprised of, among other substances: solvents, sometimes beeswax, etc.) will melt from a hard wax to an oily film.

As you can correctly surmise:
This remnant of the Wax is easily washed off; and will act as a magnet---attracting so much dust and other contaminates, as to beat the band!

Just to comment....

While a specific wax by itself may have a specific temperature at which it melts, once it's formulated into a product I don't think the normal rules for melting apply because it's no longer just a individual component but a part of a more complex formula.

I'd also add that the melting point for the "formula" could be higher or even lower depending upon the quality of the chemist.

I've spoken to a few chemists in my life about the topic of wax melting off cars in hot sun and they have indicated to me it's not like the average person thinks.


Just food for though....

If wax melted at temps stated, Florida would be know as the wax state with parking lots coated with wax.

Wax does not melt off your paint. I have no scientific data to back this up; other than using non-hybrid waxes on a black car in the summer where the panel temps sit daily @ 180°+... Beading still lasts.

However, it MAY decrease the durability of the wax slightly - too hard to say that for sure.

I would not worry about a Master Blaster effecting wax. It's just not hot enough or on a panel for a significant time span to cause an effect IMHO.

Another point that proves my point is, if wax melted off paint so easily - why is it nearly impossible to buff down a traditional carnauba wax off a hot panel in direct sun...if it "melted" - you could wipe it right off. Why aren't the carnauba plants/trees in Brazil dripping with wax?

Here's something I wrote a few years ago...




Black Car Paint Temperature in Full Sun
(And a few other colors too)

The Sun

The topic of working on a car in full sunlight without any shade comes up from time to time on the forum. While there are some companies that offer products that are stated they can be used in full sun, it's also true that all paint care products specifically and car care products in general will work better on a cool surface in the shad then on a hot surface in full sun.

At approximately 2:00pm today here in sunny, Stuart, Florida I walked outside and took some temperature readings using my Infrared Thermometer and then took pictures of the readings with the vehicle in the background to show the color of the paint.

At the time of this article I took a screen shot for Stuart, Florida from weather.com and a picture of the skyline to show that it's a clear, sunny day with some light cloud cover.

Here's a black Corvette that's been parked here since 8:00am this morning...

You can see there's quite a temperature difference between a range of color spectrums. While it's best to work on a cool surface in the shade, if that's not an option for you here's a few tips...
