craftgrrl | resin pendants question

Question: does anyone know if i can 'paint' resin onto some wood pendants im making to coat and soften the edges a bit? the brushes i use are natural hairs, but can i use plastic as well? im SO new to resin!

(i searched the memories and found nothing on this technique, only posts about casting with molds.)

***EDIT*** also, can you put resin over solder? the lead free solder.

also, i bought a container of castn craft resin. i can't get the seal under the cap to lift off. it's metal. does anyone know how id go about doing this? i feel like such a dork!!!!

thanks!!!
