Hello, I see that your Coating Resin can be used as a laminating resin - for me the positive of this is you state your coating resin "is pure" and can be used on top of previously fully/partly cured coating resin hence removing the need for sanding in between.....

Yet you recomend EL2 Laminating resin - positives for me being the different different slow/fast hardners that can be mixed etc.

Of course I want the best of both worlds so my question is: Does EL2 Laminating resin need to be sanded between layers to keep the mechanical properties and stop delamintion?

I have an upcoming project that will only allow the gradual addition of pieces of fibreglass etc. and being winter I will be working in the house therefore excluding the chance of using Polyester resin.

Regards, Rob

For best results, yes sand EL2 between layers once fully cured.

Alternatively apply directly once the previous layer is tacky, and build layers up that way.
