Hi guys im finding I'm getting dust and crap between coats on my parts I'm skinning,  are you ok to sand between coats?  If so what grit would you use.

Yeh as long as the coating has cured hard and isn't tacky anymore then you should be sanding it regardless. 180 grit is ideal for a scuff up, 120 or 80 if you need to de-nib or do any flatting down. 

So do you sand between every coat?  I usually add coats once it's tacky but finding bits in the resin that way

A VERY clean work-room is essential IMHO for a good result when skinning ..   Especially if you want to put down multiple coats of coating epoxy-

I sometimes hang my skinned items upside down, to avoid dust settling on the curing surface.

Basically skinning is like spray coating or laquering --

Do not adjust our mind, theres a fault in reality :-)

Yeah my work space is clean but it's always going to happen with the cure times being so long lol.

You can also put a plastic storage box (or similar) over the top of the piece while it cures to stop dust dropping onto it.  Many of our ArtResin and clear casting customers have the same dust issues and hence a box over the top really does help.
