does your friend do restoration professionally or its only one off for you ?
Yes if the base surface preparation is not good this happens. I have seen that in my earlier car as well. My friend only does mechanical work. But as of now he is busy setting up a earthmoving equipment workshop for a common friend of ours.

Re: MPR 4142, 1959 Fiat 103D Select Restoration.

If you see paint bubbling then you can be 100% sure you will find rust underneath. You then need to sand it back to bare metal, prime and respray. As Manish said earlier, in MOST cases of respray jobs in India the painters do not understand the chemistry of painting. You are starting with steel which is not in its natural state. In its natural state it is Ferrous oxide (rust). By painting we are trying to cutoff the oxygen and moisture attacking the bare steel to create rust. Most people do not know that body filler, polyurethane primers, red oxide etc are ALL POROUS. If you apply it and leave it in the rain, it will penetrate and attack the steel below to rust it. The prep is effectively ruined so any paint on it is also ruined. There is also a bad practice to put plastic body filler direct on bare steel. This chemical reaction also traps rust under it sometimes. So what is the solution. It is to apply 2 pack epoxy primer which has zinc phosphate in it. It must be sprayed on AFTER the metal tinkering is complete, and the body washed down with warm soap water to neutralise the acid in the welding, and then heat dried either in a booth or in the sun. The epoxy cures hard in 2 days completely. It is rock hard and imporous. After this there is no chance you will get surface rust. All body filler is put on this surface. On top of this primer, basecoat and clear lacquer. Clear lacquer is what protects the paint. I put on 4 coats. 2 on, then flat. Then another 2 on, then flat and polish. Hope this helps.

On a separate note. Quality respray is only possible in a paint booth with dust extractor and 60deg heat for 90mins. Sadly almost no one paints in a booth in India. Also clear over basecoat is far better than two pack when it comes to a glass like finish.

Best wishes. Sarajit

Re: MPR 4142, 1959 Fiat 103D Select Restoration.

Guys I am back after being blocked due to a malware attack on my PC. Thanks to GTO for understanding the problem.

Some updates my Fiat - After the mechanical restoration I have had few issues with the original distributor. So a replacement Lucas was sourced temporarily and with that car runs nice.

However The only issue - Non vacuum original carb with Vacuum distributor so I am not utilizing the full potential of the engine. But it drives great. So original MM distributor will have its paly taken out and and electronic point will be put in place.

And also it was decided to paint the car - Verde (Green), so paint shade of fiat green from Glasurit was chosen, however that turned out to be - the famous Bangalore Autorickshaw color.

So Gave a 1:18 Triumph Spitfire in BRG to paint the car.

Here is the car, getting washed after all the work.

The car in the parking. Note the eleven hundred logo which was resin casted at home.

The engine bay is all cleaned and nice - The air hose is reproduced as original by bhpian Rony Vesuna @President - Many thanks for that. The Air duct was purchased from USA and thus comes with an electric fan.

Fiat experts have corrected me on the radiator top tank color and that has been done after this. Holding good so far.

The carburetor is all shiny, thanks to bhpain DKG @DKG for vapor honing and Chandana grinding to surface grind the faces.

The ignition switch receives the badge, this is again resin cast at home from original.

Lastly it had been nearly impossible to get parts, the windshield washer bottle is one of that - thanks to bhpian Sarajit @Twincam for gifting me a broken one to measure accurately, with that I have a 3d print. so resin cast in clear will be done in near future.

Such a lovely car! No wonder Enzo Ferrari was impressed.
