I have been using Resin Obsession Super Clear in coaster molds. I am having issues with being able to sand and polish the work back to a shiny level so instead have opted to do another resin pour instead. However, the coasters are as thick as the molds so I do not think I would be able to do another layer without making a huge mess. Would it be possible to use a Resin Obsession doming resin instead so that it does not flow over the edges? I know typically it is not recommended to use different kinds of resin together but I figured with them being the same brand that it just might work. Thoughts?
