Hi guys, not sure if you know me of not because I am quite new to the forums, and haven't posted for a couple of months. I have a ke70 corolla that i bought as my first car a few months ago and I'm keeping it standard.
I'm also only just learning about cars, so forgive me for not speaking in car terms and jargon (also forgive me for asking seemingly easy questions). I have a can of $4 spray on fish oil, and although I generally know what to do with it, I want to make sure I am using it correctly and understand it fully. My car has recently developed a little bit of rust, one bit which is not just surface rust :) . The things that I wanted to know about the fish oil were...
1) Are there brands/types of fish oil that are better than others? (keeping in mind that I have the cheap one).
2) Is there such thing as using too much fish oil? Does over using it cause corrosion of paint etc?
3) I understand that there are different types of rust preventative for the under side of the car, would the fish oil that I own have any effect if i sprayed it, for example, under the wheel arches? Or am I just wasting my time?
4) is it a good idea to lightly scub the area with, say, steel wool before I apply the spray? am i in any danger of ruining paint if i do this?
5) will this stuff do anything at all for my non-surface rust? Will it stop it from spreading?
6? *NEW* will washing my car render the fish oil useless? like, will i have to reapply it after every wash?
cheers!
