    I have scraped the binding on this body and now I see fine scratches have appeared in the transparent base coat. I have been super careful with handling and can only think that they are caused by it being in my lap while I was scraping the binding, could this be the cause? Can anyone please advise my next move?
    Do I simply clean it with Naphtha and spray the gloss clear coat?

    Any advice will be appreciated.

    A couple of the scratches can be seen in this pic, but there are quite a number of them all over the body

    If they are in the base coat and that was covered by further layers of nitro, they SHOULD have been filled in and disappeared, as new nitro coats normally melt into the previous coats of nitro...are they chemically dissimilar paints/finishes?

    If there is nothing on top of the basecoat yet and another basecoat would change the color too much, anything other than gentle sanding would probably result in a sand-thru.
    You could try a LIGHT coat of clear nitro to see if it melts into the nitro basecoat and smooths out. In theory it should.

    Good luck!

    Have you sanded that finish? When level sanding with very fine grits, you have to be very careful. Tiny little clusters of the sanding dust can ball up and lodge in the sandpaper that you don't even see. Circular sanding with the crud in the paper leaves scratches much deeper than the grit scratches. Top coat clear several coats, and then level sand again. Be advised, nitro shrinks a lot over time. You can get it dead flat and then over the course of several months it shrinks back enough that flaws a grain telegraph through (especially if you've put it on real thin). Very nice color choice BTW.

    I would not treat those scratches at all. Clean as normal, and follow with clearcoats...they will 'repair' those marks.

    I agree, clean it with naptha and hit it with a couple nice, thin clear coats. Carefully sand it with a block and 1000 grit sandpaper, wet with water or naptha. Repeat as necessary. The final polish will be where you can buff out any remaining swirl marks.

    Nice color! Looks great with the binding.

    Thanks everyone :) I will clean and spray a couple of clear coats, to start with, and see how it looks.
