Otherwise you will struggle to get a gloss finish at the end. Also bear in mind that many diminishing nano abrasives (such as our NW1) will require a fair bit or working to break them down from the initially coarse compound into a finer polish. If you polish it off too soon before the polish has broken down then the gloss will be poor.Also be aware to ensure you have left the resin long enough to cure in the first place. We recommend a minimum of 48 hours at 20C before any sanding or shaping takes place - if your room cools over night, you might be trying to sand green resin which will always be difficult.
