That is a sound idea. I have a plastic 'squeegee' which accompanies some car filler in my garage. As you have made clear, it will make life easier.

I am interested in the application method you have suggested. I am now confident I will be able to undertake this method successfully, but I would just like to clarify a few points. I am under the assumption that the resin coat which is applied to the balsa is just resin and not mixed with hardener. I am also assuming that the final coat of resin/hardener mix is applied once the fibreglass and initial resin have totally dried and set.

Thank you.
