adding fiberglass?

i have built a custom enclosure for me car, the "skeleton" is done as well as the Fleece. i placed it in the vehicle and i really like it, however there are a couple of places that i would like to add a little. there is a step on one side where the higher it gets the wider it gets and i want to fill that in so to speak so can i get a piece of wood, apply it on the outside of the fleece and then fleece over the additional piece? thanks Louie

hey bellsracer, thanks for the reply, i wish i could have added a picture to clarify buyt my gf too the camera from me..haha i ended up just pullingi the fleece and the staples and adding in what i wanted and then re-fleeced. however yes that is basically what i was asking. i had a completely fleeced project and i wanted to add another piece of wood onto one side, over the fleece, and then fleece that piece of wood, but being unsure about it, i just pulled the fleece off. thanks for the help, and my shop wreaks like resin :)
