Vacuum bagging a kayak repair?

Hi,

I have a smallish hole (4" x 1" by the time I have removed damaged area) to repair in a glass fibre kayak. The original layup is chop strand matt, woven cloth and polyester resin with white gel coat. The hole is inside the cockpit area and I have good access to both inside and outside to carry out the work.

I see a lot of poor quality glass fibre kayak repairs and I'm sure it is possible to do a lot better. I want to avoid any big clean up, gel coat filling & sanding etc on the outside and I definitely do not want the patched look that I see too often.

I have seen the excellent composite kayak repair video but I don't think it would work the same way after cutting out the damaged glass fibre.
However I would like a high quality, strong and invisible repair.

I was thinking that using the vacuum bagging technique to improve the strength and cosmetic appearance of the repair might work well.

Would it be possible / recommended to start with a suitable mold surface for the outside, release agent, gel coat, layup and then bagging inside and outside? Maybe it's not possible to pull the vacuum with the hull in the middle?

Would you be able to advise on process and materials?
