I recently detailed my car and in many spots what I assumed were bug guts were little rust spots. Does anyone have any suggestions on how to handle this? I know you can buy paint that roughly matches the car’s paint, but is there some kind of sealer I should use first?
The paint is the sealer that will keep that area protected, but first the rust should probably be removed or neutralized via physical means (grinding) or an acid.
And on top of all that, that’s what waxing is for, both to even out micro imperfections in the paint and to serve as a sacrificial protective layer.
