Hi there

Unfortunately no, I don't have access to a pump (that I know of!). In fact i'll be buying all tools/materials from scratch to do this job, it's also unlikely i'll be doing many more jobs like this in the future

I did look at a sandwich approach but was unsure how it'd work with all the contours. I'll have a search around to see if I can find any examples.

With regards to the resin; yes polyester is typically used. The surface is usually prepared with either plastic lining or masking tape before the resin/mat is applied.
