The rust was just tiny little specs, most of which was stained from where the back of the rockers rusted, and not on the body itself.
We all thought RTV would be just fine instead of a gasket. It didn't work THAT well. When I put them back on, I'm not going to use a gasket.
There mostly used to protect the paint under the sliders, but seeing as mine is already uglied up from the RTV, there is no point...Also, I've read from a few respectable fellas, that the gasket will also trap contaminants (sp?) under the guard (being that the seal isn't PERFECT, which it's most likely not going to be) , and not having one will let the contaminants clean out easier.
This time i'm also going to use some griptape on the steps to help make the paint last longer where my feet use the step.
