Hi,

I'm at the final stage of the skinning process and although I've made some mistakes along the way I'm generally quite pleased.

I've applied the final finishing coat which generally looks great however there are quite a lot of minor tiny spots (like pinheads) over parts of the surface, it looks like perhaps some dust although I was very careful with the preparation. The surface is otherwise very flat and glasslike and with a great gloss.

I am reluctant to go through the stages of flatting the surface with 400, 800 and 1200 papers and would like to try flatting with just  the 1200 to (hopefully) get rid of the tiny pinhead spots and then use the polish. I guess if the 1200 doesn't work I can go backwards  with the 800 and if necessary the 400. How important is it the flat through the various papers if one is happy with the 'flatness' of the coating.

PS I have some unused white polishing compound from a few years ago is it OK to use this or do I need to use the latest (black I think) compound.

Regards,

Jeff

Thanks Interloper for that info on using white polishing compound, you may have saved me a lot of extra work.

Until I flat I'm not sure whether I'll actually have pinholes or whether the 'pinheads' will flat out.

Will get some black polishing compound in any case. I will post results.
