Hey everyone, i just picked up an 05 evo 8 with 30k miles and the underbody has some slight oxidation and paint peeling from being driven in one winter and then sitting for over a year. There is no rot or rust holes or anything but i just pulled the engine and tranny and im building the car and im going to just do everything while i have it all out. What is the best thing to do about it? Should i just bring it to a body shop and have everything re-done or what is the best option? Just need some help thanks.

 

anyone?

 

like under under body?

I'd sand/grind it, rust inhibitor, and then just recoat it with paint and underbody sealer.

if its under body....

 

for the most part its under body there is a little on some of the suspension components too like swingarm and what not but its pretty light.

 

All the suspension components on the evo are aluminum so rust isn't really a concern. You can however clean it up with engine degreaser, works well, or aluminum cleaners.

 

If you are concerned about it then I would reccomend that you jack the car up as high as possible, take a pressure washer to the factory (garbage) undercoating and remove as much as possible. Let it dry overnight. Then re-apply with a higher quality undercoating.

This is what I used and the results are fantastic.

Overall it took 2.5 days for me to clean and re-seal the underbody. Note that my car was previously used for rallycross and at least 12 hours was spent removing the massive accumulation of mud that was caked in everything.
