Hello I am making a 3D picture frame which is a4 size and 32mm deep. I am putting an assortment of keys inside (dad is a locksmith) and want to fill with epoxy resin to set he keys in however I want to bring it 2mm below the picture frame level which is 32mm deep so about 30mm deep of resin. however some parts of the picture will not be that deep as the space is taken up by some of the keys. I need the surface to be clear so you can see all the keys inside and the backing of the frame which will be black. I want it to be clear but do not want to have to sand and polish it as it will be 2mm below the frame level and will be hard to sand and polish without damaging/scratching the edges of the frame. If you could tell me which resin to use and the application method that would really help me out, Thanks very much in advance!

Hi Harry,

Yes, if you combine the GlassCast 50 and 3, as you propose, the cured piece will look like a solid block and there won’t be any evidence that it was made up of more than one layer.

All the best, Matt

Thanks for getting back to me Matt greatly appreciated. I have one more question I have ordered GlassCast 50 but now realise that what I need it for is not anywhere near 25mm thick. Some parts will be maybe 15mm and other pars will be down to 4mm. Will GlassCast 50 be ok to use for this or does it only work on thick sections? And when that’s at stage b I will add the GlassCast 3 I have bought as final layer that won’t require sanding and polishing. Thanks, Harry.
