Soda blasting the car tomorrow!!

[degreeoff1]

Yeah you heard it right....I have a guy coming over with a big assed trailer to "soda blast" my ride.......Does it on site with an air machine and baking soda...I'll let you know how it turns out...pics etc...will cost me about $400 bucks.....

Damn I have not been this exited since I bought my motorcycle....

Mobile soda blast, who gets to clean up the mess?

[degreeoff1]

wee bit dusty but evedently only 50 lbs or so used....rinse off the driveway and kill posion ivy downstream to boot

My place it won't matter......youd have to see to understand...but its ALL good :-)

[Travis Neff]

Just have them do it in the front yard and hang up some x-mas lights. Christmas in September!

[Lou Rachwitz]

Take lots of pictures

I had my 914-6 soda blasted anout two years ago. I think you will be surprised, It takes longer than you think. The original paint and primer are on there really well. The repaint came off in a second. AL:

[degreeoff1]

Look at the work I have already done...I think you'll agree it will not be long....all hoods skirts etc are FG...:-)

Well, be carefull. The guy that does mine does a 2 step process. First step is something similar to crushed glass. It's sharp and removes bondo, paint, primer, etc very quickly. It then gets finished with a plastic media for the proper primer bond. No matter what the product, if they stay too long in one spot it will generate heat and warp the panel....

it does not generate enough heat to warp a panel... "Hello Myth Busters"

Cant wait to see the finished product...... Any more pics where your bonding the FG flares?

I have never seen the process done with that particular media. However, from common sense I would only assume that if there is enough action with any media that can remove paint from using the end of compressed air nozzle that someone not knowing what they are doing could warp a panel.......When you strike metal with any media from a projectile (nozzle), long enough it acts like a peening hammer and "moves" metal. I could put sheetmetal in my abrasive blaster and literally reshape it if I stayed at it long enough. Agreed, this media is very light and unlikely in the right hands but "right hands" is the key here.

On the other hand, blasting does generate heat. If you don't think so, aim a media nozzle at the end of your rubber glove. It gets hot in a couple of seconds.

So there is really two issues. The media, air pressure and length of time in one spot has a great deal to do with the results and the heat\warpage generated.

Now apparently the claimed benefits from soda are :

Unlike abrasive sand blasting, sodium bicarbonate particles remove contaminants by the energy released when the particles explodes as they come in contact with the surface to be cleaned. Sounds good.....Please post pictures of the results.

Anyone tried blasting with dry ice? Some companies will do this process on site as well. It's supposed to be easy on the base metal and it evaporates. (i.e. no abrasive left over except the old paint/crud)

I just don't know if it would work on removing paint/bondo.

I didn't say it doesn't generate heat. I said it doesn't generate enough heat to warp a panel. It's the localized pressure as you laid out quite well in your first paragraph.

Some of these guys have some serious pressure coming out of their machines. For them, it simply helps get the job done quicker. Again, as you mentioned, get it in the wrong hands and your nice smooth panels can be toast.

You can reach out and touch a panel that's been blasted. It's no hotter than your car is sitting in the parking lot at the Ventura car show. So, I'd have to again say there's "one" issue. I own a sandblaster and with our control arms, hubs etc. we work with a professional sandblaster on a bi-weekly basis.

Do some Googling on the subject. It's actually spelled out quite well by others.

I'll tell ya this thing rocks!!!
He is 2 hrs into it and it is almost done...Given it is just the unibody....trunks are CLEAN!!!

My cameras disc took a sheet so I will have to get pics tonight but there is little to no heat from the process and the metal is as clean as the day it was formed...

I'll update later tonight...BTW LOUD as HELL!!!

[Va914]

Nice

So you have 2 weeks to get it all back together and over to the ECC, right? LOL

C-ya in two weeks

[Acox914]

nice work.

no offense, your cage is a little scary....
why is the rear hoop so far forward? the trick is to get em as close to the targa upright as possible, and about a 1" piece of metal connecting em to the seatbelt upright mount...

im worried about your in/out access thru the door with both hoops so close to each other......

[degreeoff1]

add wide angle lense, back pad and walla there it is...BTW that is as far apart as I could get my bars...the autopower weld in lit was to say the least a tough fit, there is 25" between the bars

As I understand it, soda blasting will not heat up the metal bbecause it works in a totally different way than other meadia blasting techniques. most media blasting is an errosive process, that will erode anything in the path of the energetic "spray" of media. soda blasting works because the individual crystals of the soda media will fracture and break apart on impact. this releases a tiny littel "bomb blast " against the surface. when the crystaline structure is fractured, energy is given off. the advantage is that it WILL NOT errode the surface, nly the coating by bombing it off!

From a web site:
"Unlike abrasive sand blasting, sodium bicarbonate particles remove contaminants by the energy released when the particles explodes as they come in contact with the surface to be cleaned. Silica sand on the other hand, removes the material by wearing it away. This is also the results when the sand hits the metal surface, the metal is worn away and the saurface is damaged."
here is a pic of mine soda blasted.

this releases a tiny littel "bomb blast "

No *****... look what it did to the house in that picture!

No *****... look what it did to the house in that picture!

and it blew all the leaves off the trees. is that snow on the ground or the soda? it looks like winter there.
