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.

Warren, Thanks for the info, just a couple of questions. What grit do i need to sand down too? Could you also explain what you mean by the polish breaking down? Do you mean that i need to polish for longer with the polishing machine? if so how long do i need to polish for? Thanks alot Myak

Here’s the top and reverse of the table. Trying to upload pic but it won’t do it ??? Edited 7 Years Ago by Bhamoggy

Already preparing for second project. Gonna be a Brighton beach table. Just laid out in preparation. Will do 3mm first pour hopefully tomorrow. What do you think of this?

Diminishing polishes you will feel it as they break down and move easier becoming finer. The shells look good, but you may need to secure it all down with a thin layer of resin to avoid things floating away. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant
