I have this revo chassis here and before I put it back on. I want to de-ano it and change the color. I doubt I need to de-ano it if I am just going to spray it. So questions are..

Do I need to de-ano the chassis before I spray(just want to be sure).

Would a paint job hold up(thinking something along the lines of a engine block paint). I dont care about areas that will have parts bolted to it,no one will see it unless I take it apart.
Or should I just get it done without using paint?
