Default Engine corrosion

Hi everyone.. The engine of my 5-door hatchback is seen to be undergoing corrosion. I am intending to do some powder coating from ACL http://www.automaticcoating.com/serv...owder-coating/, in Toronto. Do you have any other solution regarding this issue? Or do you know any other store which provides a solution for this type of corrosion? Please share your opinions

uncoated aluminum and steel parts are subject to oxidation. when a durable coating is applied evenly and to the correct thickness and hardness, there should be years of corrosion free use.
two of the most durable coatings are powder coating and anodization.
i used to work in a paint shop that used powder coating, and i would often drop hot and fresh painted parts onto the concrete and they would not show any damage

usually aluminum parts are hand sanded before, and steel parts are put inside an automated lead-bead blaster.

powder coating is applied through a gun that is positively charged and the parts are hung onto a steel rack with wire hangers and the rack is connected to negative. the gun is sprayed around the part and the coating adheres evenly. (usually)

after spraying the part goes into a cure oven until the coating bakes onto the surface of the metal.

Had some surface rust on bottom of intercooler pipe - wire brushed it and sprayed it with Rustoleum - held up for a few years.

I do/did powder-coating. It is not as durable as often thought but better in most cases. Every part is different.
As for anodizing most people only get regular anodizing witch is not only porous but will scratch to look at it. Like everything else there are different type of anodizing. Normally as a personal preference I get many of the things I wish anodized "hard anodized",.

There is nothing wrong with good old "RATTELE CANNING". There are some Epoxy paints for things needing a durable coating. But generally the rattle can paints work rather well if you follow the information on the label for preparation of the work and any curing procedures.


However if you have a full wallet $$$$ get your items powder-coated.

NOTE: it is better to find a Powder-coater that is experience with engine parts or at least a car enthusiast. TRUST ME ON THIS POINT!!!!

Maybe? But the topic of the thread and the responses so far are pretty good?

Thanks for the replies.. You people spoke a lot about powder coating. What about liquid coating? Is it good to prevent rusting?
