When sanding a Aero bumper, that has spider cracks in the paint. Do I need to sand all the paint (cracks out)?? Thought I'd ask before starting the process.

You need to sand the cracks out... you don't need to sand all the paint off, but sometimes that will happen in order to not see any more cracks.

Depending on How Long, and How Hard it was hit, the" Cracks" may Be in the Skin of the Urethane Also ! If that is the case, all the paint must come off, the urethane roughed up, skim coated with flexible parts repair (Such as 3M makes), then primed and painted.

If just the paint is cracked, you HAVE to sand that area completely down to bumper material. Lou is also right that they may also be in the cover itself. It may be impossible to see them, so you do need to sand off all the paint and put a skim coat of flex filler on it. They will eventually come back thru the new paint if you dont...even if you dont see them in the primer coat. If the covers had stripper on it, it can get in those cracks too and never come out except to ruin the new paint. Any covers I get that have had stripper on them I throw in the dumpster no matter how 'good' they may look.
