ok im building a 302. making alot of progress on it. but its gonna be a long term project but i dont want it to rust. so what can i spray on it to make it so it wont rust so i wont have to get it bored again. the guy at the shop said wd40 but that sounded kinda wierd
Wd-40.
wd-40 works great, even on bike engines, so def do it
I have a Block I honed a year ago and sprayed with WD-40 and last week I looked at it in the old 12x12 metal shed setting on concrete and there is NO rust on the cylinders.. WD-40 was made for the NAVY works great.
