Is it possible to add further layers of prepreg to a cured part and re-bag & bake?

Will the resins bond ok to the cured parts - I'm assuming the cured part will need keying up?

Thanks in advance

Cheers guys good know it will work, I've found the easycomposites prepreg very good with quite a rich resin content -  will take also care with vac bagging I've had my share of frustrations with maintaining a vacuum because of an unknown pin pick somewhere!
