You are never too old to learn new techniques. I have been making car parts out of fibreglass for nigh on 50 years with a lot of success.
Started off simply attaching arches to Anglias and progressed over the years to culminate in producing moulds for prepreg carbon parts including the complete front clip for the Elan.
Over the years I have used the same method - cut the FG piece to the required size, lay on a board, soak with resin, pick up and position in place. Works well if a little (OK, very) messy but I knew no better.
When making the mould for the roof I used this method for the first section, angain no problems apart from the frist layer of lightweight woven cloth being awkward with a mnd of its own. The subsequent heavier layers weren't a problem.
However, I was watching a video of an Australian guy making a mould for his race car and noticed that he brushed resin on to the pattern first then added DRY FG and brushed on resin afterwards. This was a lightbulb moment! SO much easier. I made the second part of the roof mould using this method - cleaner AND quicker
One downside of this method is that it traps more air bubbles than the wet lay method.
It has since transpired that this is the normal way to do it and even my son does it this way! Oh well, better late than never
