Winter storage and aluminum parts Oxidizing

Michael Soldan · Nov 20, 2019

My car is winter stored and every spring I find some oxidation on the aluminum intake and various aluminum mounts for alternator , mounting brackets etc. What do you put on these parts to prevent oxidation , I was going to try some spray oil and wipe everything. I'm interested in what you use.

the only way to prevent it is to clear over it and even then its not a great long lasting finish. Aluminum oxidizes, that is just what it does. Check this stuff out as I have not found any better. The green liquid just wipes the oxidation away and a couple quick rubs with the purple and its golden.

Mine does too. Not much you can do.

I start mine about every 3 weeks, seems to help, but the condensation is what causes that corrosion to form.
only way to stop it is to keep it dry, that is why it does not happen as quickly in the summer.

I had a MCA Judge tell me he had good luck using WD-40 on bare aluminum to help keep it from oxidizing. I have wanted to try it but have not as of yet. Said just spray it on well and wipe down. WD...Water Displacing...makes sense but, again, I have not personally tried it.
