Hello all,

Hi,

No need to do anything but add the epoxy on top!  It will "fill in " the matte surface of the polyester - making the whole thing clear.

In essence, the "matte" surface on the polyester consists of a myriad of tiny scratches from the sanding, these will fill out with clear epoxy..

If you tried to polish the polyester, the epoxy will not bind to it, and would definitely delaminate very quickly..

Also remember to degrease the surface very thoroughly!!

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

Hi Dravis,

Thanks for such a quick and helpful answer. It's good to hear that the sanded surface is actually beneficial! I'll have a go and will make sure to degrease first.
