I removed my grills to replace the washer pump hoses and discovered that there is alot of brittle and cracked (I assume sealeant) that was originally used to seal gaps or whatever. What type of sealer should I use to repair all this brittle and flaking material? Also does anyone know what the correct finish should be for the screws that hold the grills in place? The ones I removed looked like they were chrome and someone painted them black to match the car finish.
