Re: Is there a way to buff out a scratch ?
You're sure it's through the color? Hard to tell from the pic. Have you tried wiping across the scratch with something like Prep-Sol (a wax/grease remover) or maybe a little mineral spirits? If it's just the clear, wetting it like that will let the color show through the scratch and let you know for sure.
If the scratch isn't that deep, you might be able to polish it out - but if it's all the way through the color, you're not going to buff it smooth without making it look even worse. Remember, you're going to have to make the surrounding area level with the BOTTOM of the scratch to make it go away if you're just buffing.
Your best bet then would be to match the base color as closely as possible, touch it up where its gone through, then fill the remaining scratch with super glue and wetsand and polish that smooth. Then you're not taking away any more of the surrounding clear than you need to, and the repair will be almost invisible.
If it's NOT through the color but the scratch is still fairly deep, fill with super glue, level the fill, wet sand, polish. Done.
Might wanna practice on something you don't love a couple of times before you have a go at the new JPM...
