Thank you for all the input
Abstract: The abstract of the write paper is to investgate the current available store bought, low cost, so called "engine enamel spray can paints" and compare to
various low cost red colored enamel spray can paints.
To be technically correct the engine should be painted with low cost spray paint rated at 500F rather than spray paint rated at only 200F. Using higher cost 1200F rated paint design for exhaust pipes and brake calipers is an overkill.
There are many choices of low cost spary can red colored paints available in the market space but not so many low cost spray can engine paints.
Undoubtely there are high end industrial paints costing upwards of $150/ gallon that will hold up to the engine temperatures, which many have used. Could paint 10 belly tractors with a gallon of paint.
Made a slight typo error, should read 1948 rather than 1940
Do not know if this is even correct and do not even care.
"There is school indicating that Ford tractors built between "1948" to 1957 were blood red similiar to IH red while Ford tractor built between 1958 to 1962 were orange red."
I knew if the results of my research project was posted on the forum, many would throw "red" bricks at it. I wellcome the bricks.
There are no theories here, just facts.
From reading the achieves it is apparent that owners do not in general paint the engine with paint formulated specifically for engine application, but use the same paint for the undercarriage and engine. After all Ford painted entire belly and engine with the same paint. This was a lead based paint with lots really nasty chemicals in it.
Personally, I wanted to paint my engine with modern formulated "engine paint" rated at 500F, rather 200F rated paint. Current high end industrial type paint would most probably hold up to engine temperatures, but his was not considered in the research project.
Also, this paint is still not designed for engine application.
Only low cost, off the shelf spray paint purchased at auto stores, hardware stores, TSC and Walmart were considered. Afterall the tractor is a work horse, not a show horse.
Typically older engines ,especially flat head Ford engines are less efficient than modern day engines. The percent of heat generated compared to total energy generated
is much higher in older engines than modern engines. Also, pressure die cast engine blocks are not painted in modern engines, compared to sand cast iron engine blocks, which were painted with "lead" based heavy metal paint, which held up very well to engine heat.
Off the shelf paint formulations of spray paint enamel ten years ago is much different than the paint formulations today because of EPA regulations, Even, the paint formulations one year ago are different than the off the shelf paint formulations available today because of EPA regulations.
The state of California levied stiff fines on TSC for selling Valspar tractor paint, which had higher VOC than the regulations allowed. TSC pulled the paint off the shelf about 6 months ago and replaced it with some inferior paint with LOW VOC manufacturered by Yenkin-Majestic with a brand name, MAJIC , sold exclusively by TSC.
TSC decided to pull the paint from the shelves in all states and replace with MAJIC in all states.
Older vintage paint fades even red, with age, everyone knows that
Many autos today are painted silver color and is a modern popular color, 20 years ago the silver color had a major fading issue and few autos were painted that color. With modern chemistry the silver no longer fades.
Using the same TV, watched promotional films made by FORD dearborn tractor & implement divsion and IH Farmall division in the era.
The promotional film, titled "the new ford tractor ,1953" the Jubliee is orange red in color compared to the Farmall Cub protional film showing a dark red (violet red) colored tractor. Also a Ford dealer promotional film titled, "Ford tractor construction levitown, PA" shows tractors that are orange red and not IH red.
Spectrum analysis
The reason the color spectrum analysis for each paint sample was included
to show the percent of red. violet and yellow for each shade of red tested.
The IH red is basically identical to regal red.
Using the spectrum analysis results the engine paint color is compared to the general purpose paint to determine the best match, rather than relying on the eye.
The higher the percent of violet the darker the red. Most red paint in the market today based on spectrum analayis contains some violet which places the color on the blue side of true red rather than the yellow side of red.
Special color mixes of high end paint from PPG or Sherwin Williams were not considered costing upwards of $150/gallon.
The report gives the best engine paint color matches for those who prefer orange red for the undercarriage, best match for red and the best match for violet red.
There is no attempt to determine what color Ford painted the tractors, but do have my own opinion, which is stated in the report.
There is no statement in the report saying, if the engine was painted with a non engine paint, then the paint will not hold up to engine temperatures.
That is the bottom line.
