White Epoxy Paint

Having my engine rebuilt at TAD. They only have perkins blue paint. I wanted it painted in white to brighten up the space and to show leaks easier... but I would have to supply it myself.

Any ideas on the correct paint to use on a engine and transmission?
I looked online of course, but figured asking for advice from someone that has used a specific product is better.
Thanks,
Bob

I was the same, wanted my engines painted Cummins white, being cummins after all and for the exact reasn you gave, oil leaks and bright.

They turned up blue as well, the reasoning being that the white discolours badly wherever the engine gets hot and since then have seen a few white engines and they were correct, the white has gone brown in areas.

FWIW

add: If you realy want white, why not just get it from TAD's paint supplier?

TAD says If I wanted it white I would have to supply the paint.....
I have seen john deere luggers with thousands of hours on them still white and shinny. Guess it depends on the paint, hence my post.

It would have to be a high temp paint.
I guess the blue would be ok, but much prefer white.

2 Part Epoxy

Any 2 part epoxy will work fine. They can 250-300 F. no sweat. Be sure that there is "NO" oil on the surface and wire brush/ sand to remove any loose paint and rust. Should last for years.

After two years, my Cummins engines are still bright white. Perhaps they changed the paint formula? Epoxy is too hard of a paint to put on an engine plus it is a pain to remove when you need to do that. I would just go with spray on, one part high temperature engine paint.

POR makes an engine enamel in various colors. It's a one part that is easy to apply with a brush. The paint contains isocyanates so paint in an a well ventilated area and don't stand over the engine deeply enhaling the aroma of your newly painted engine. If you are going to spray it, be very careful. A particulate mask will not filter out the isocyanate fumes.

The engine needs to be free of oil so should be washed down with their cleaner if it's not already squeaky clean after the rebuild. I used it on one of my car engines. It still looks fine after more than 10 years.

Why don't you paint it yourself when it comes back?

Its a good question chief... thinking about it. But not sure if the time it takes to get back here will cause it to rust or not, doesn't take long..

I checked out the POR brand. Looks good. I will send a pint up to TAD and let them paint it, then touch it up prior to the dealer reinstalling it.

My mistake, the ones I saw that had discoloured were isuzus.

Not everywhere, just around the hot bits.
