Basically YES Respray.

Scratches depends on how deep and are you prepared to go as deep as the scratch.

Chips can be filled i with a touch of colour cure then acrylic clear a few coats to build up the layers. then once the last coat has cured for more than a week. I sand it down with 1500 and/or 2000 then remove sanding marks by buffing them followed by a similay process as seen from MRWATO2U's pics on the AADz link.

Deeper scracthes can also be wet sanded down to reduce the buffing time.

Yes I have wet sanded expensive cars like Mercs worth over $300,000 before.

To, nicksrex I have notice you are a AADz member too, would love to see a pic of your rex on AADz site.

Hope that helps
