Hey,i think this question is already on the site but i couldnt find it so ill ask anyways. I'm wondering what is the best type of afterrun oil to use other than the kind you buy at the hobby stores. i heard you can use transmission oil and some other kinds of oils. i currently use WD-40 in my Savage. so if you have any tips or comments comment. one more thing, can you mix oils and use them as after run, what i mean by this is can you use WD-40 and mix it with some other oil that is a good ARO and make is better or something like that. sorry if the question is dumb, I'm fairly new to this. Thanks
