Hi,

I have skinned some car parts for my car using the XCR kit.

I have skinned quite alot of parts and have got to the final stage of finishing with 400-1200 grit sandpaper.

I am looking to speed up the process by using a sanding machine with the 400-1200 grit papers.

Which is a good sander to use?

Hi guys,

So I have tried sanding one of my parts.

I used the following grits- 320, 600, 800, 1200, 1500, 2000.

It gave me a decent result, but not up to the standard I was hoping for.  The final product is smooth but is slightly dull (not a nice reflective part which looks new) and almost looks like a 2 year old part.  When the light hits it from the correct angles, I can see tiny little scuffs on the surface.

I am making the assumption that this effect has been caused by not sanding well enough that all of the scratches caused by the previous grit have been removed.  My question is this; how can you really tell if you've sanded the piece well enough using a particular grit; before moving onto the next?

I guess I am going to start from 320 again to try and hopefully I get a better finish this time; but I need to work out the above first.

Also, I've sanded this particular part quite a bit now- trying to improve the imperfections from the surface and I am weary that I may at some point sand too deep and effect the cloth.  If I was to drop down to 320 grit and then applying another few layers of resin over the top- would the scratches lower down still be visible or would it be just like starting afresh with the finishing process?
