What to do to protect a transmission case after cleaning has been a recurring topic over the years. Originally the transmission were covered with a 'cosmoline' like product which is a mix of wax and oil to protect the metal from corrosion. These products are still available and some people are recoating trans cases with this stuff to good success.
But that coating remains sticky/tacky over time. I don't like that. So I've been trying to go the epoxy primer route. These primers form a chemically hardened coating that'll last for years, isn't sticky, and looks great. This blend of epoxy primer I used on the latest 915 transmission build is pretty much perfect color match and what I'm calling Magnesium Grey. The idea was to coat the case with something that essentially looks as close as possible to bare, oxidized magnesium. The only problem with it, is that they can't mix anything less than a gallon. (IMG:style_emoticons/default/blink.gif) So anybody need their transmission case painted? I'd love to run through this gallon ASAP. |

Main goodness with a confluent hard coating like epoxy is that unless you heat the trans in an oven, the porous metal will have petroleum retained that will off gas, seep, etc. The epoxy acts like a hard shell. Ive never really had issue with any method I tried, but I don't have a set up to clean the cases so I just don't. In the future, I plan to do vapor/sonic once life settles down and I invest even more into my business since it is now helping cover living expenses and not a hobby. Cool write up and I look forward to more data. BTW, I have had many swear by Gibbs as the closest to stock and longer lasting. The Tectyl was OE and wore off shortly. Kind of silly. |

The Tectyl was OE and wore off shortly. Kind of silly. I wondered about this. I have a can of Tecyl that I planned to coat mine with, but wondered how long it would last. Available in quarts on Amazon if anyone is curious: https://www.amazon.com/gp/product/B00HUY8PY...=UTF8&psc=1 |

Available in quarts on Amazon if anyone is curious: https://www.amazon.com/gp/product/B00HUY8PY...=UTF8&psc=1 Only problem with these is they remain soluble in organic solvents (gas and oil) and are susceptible to removal by hot water. Not sure how long term they are in a dynamic environment. Mainly designed for protection in long term storage. |
