can any of you ladies recommend a decent brand name of clear fibreglass repair resin for fingers or toenails? I need it for my modelling kits to cosmetically alter the shape of me cars exterior and to build parts I need to fit new additions like,

I am converting a 1969 Yenko Camaro 1 / 25 size kit car, with twin auto focus web cams with motion detectors for headlights, a built in mini mp3 player with speakers, (speakers from my old mobile phones) custom interior and custom paintwork/ graphics,

I could buy normal fibreglass resin but it is to thick and wouldn’t work to well so any suggestions would be appreciated.
