I think if we reduce the pressure of the compressed air the velocity of the media is reduced and then glass beads can be used to acheive the desired results without destroying the chassis. But then no ventor will be ready to do that.

Simply put you need to get a new chassis then.

You might not see the rust very clearly but trust me its there and Pavan know too. Its gonna be a nightmare to get that chassis rust free.

The first places the rust will erupt in are the welds where new metal has been grafted on

Been there and done that so I speak with experience

Wasif Bhai what is this process of chemical dipping of the chassis that is so prevalent in the Uk ar there any places to get this done in India? Is that an option when the chassis is in bad shape? Or the metal is thin like what Pawan has observed on this particular chassis.

Chemical dip is a great way to reach all nooks and crannies of a chassis with rust preventive substances.

Not sure if it is availabel in India, you guys live in India so you might know better.

It does work well though and will not take away any metal from the chassis.

usually items are media blasted to ensure that all surface rust / paint etc is completely removed and then dipped to seal the said item from rust.

This is one of the reasons the restored cars last much longer in the west as the basic issues of reust are addressed in fitting manner.

Now in India when you patch a rusted area what happens is sooner or later the rust starts up again around the welds and even the edges of the patch.

Hi! Are you serious? This is a wonderful sentence for forwards.

Topolino chassis may be thin, but they are engineered to survive. But now you have to check if you have lost any metal, then the chassis becomes weak. Thin and weak are different situations.
In the very first car which we restored and was partially hands-on, we scraped down the chassis and then used a hand drill with a steel brush to clean the chassis properly. But sandblasting and dipping in a tank like galvanising would work better.
BTW, how is the engine?

In chemical dipping there is no media blasting, there is acid then neturalizing, then cleaning with water and once dried a spray of protection.

Chemical dipping is prefered when we have delicate parts which might get damaged by the media (from blasting).

How ever much also depends on the Guy doing chemical dipping, too much of dipping can also eat away the metal. Chemical dipping will go to every nook and crany of the component or part, which is a good thing.

As far as I am aware that much big tank is not available in India to carry out dipping of the whole body. Chrome platers also do chemical dipping before chrome plating and many times to scrap old paint the same acid is applied by brush over the body by local painters.

Would you know what acid or chemical mix this could be exactly?

hydrochloric acid, but then the one used for automotive purpose might be slightly weaker than the locally available ones.

Also phosphoric acid is also said to be a good agent. HCL is faster of the two.

All said and done, practically in our country we are handicapped with such kind of technologies being absent

We have given it a nice 2 coats of 3M antirust coating , initially i needed the Wurth guys to do it, but they have been giving me nightmares with their timings since 3 days.

3M is a rubberised compound and coats the surface neatly.

Yeah that's the main grouse and even if that can be adopted our mechanichs or local guys are unwilling to do so that's even more bigger issue.

guys like you and Pavan with the knowledge you possess should take the plunge and get started in ofering these services in India

Bhaijaan, that was a bit tooooo much

Some more pics on the chassis.

As on today evening, the work on the Chassis is DONE.........!

Lot of detailing has gone into the making of this chassis, Rust proof, Well detailed and as straight and square as possible.

Tomorrow onwards work on the underbody of the shell will start. I hope the commitment levels of the team remains same.

You have a good point, at one point of time I dreamt of a resotration shop (I even met Manvender Singh at an age of 16 to work with him). Now I work for a different Industry.

Chassis looking good Pavan.

Seriously guys ....why not look inot offering such facilities and others like hi class paintwork and chroming under one roof....surely a recipe for success

The Chassis has turned out CLEAN sir, we have not lost any metal.

ENGINE..................! all i can say is " Its running fine right now sir"

I dont know, what ghosts come out once its mounted on the car.

Sirjee, in such case, i need to start charging fees for all my restorations. and make it a Business. In which case, i will loose my passion and become a pucca Business man.

And i dont want to do that.
