i removed the old fabric and foam from my board and there are a couple spots that are deeper then the rest of the surface on the fabric side, will the fabric cover this or do i have to fill it somehow, and if i fill it will the adhesive stick to that part?

 

first off how deep are the spots? if not very deep u can spray the board with adhesive then use masking tape on the spots then do not reglue over the tape then it will not show at all hope this helps

 

the spots are not that deep, if i use tape how is the fabric supposed to adhere over that spot without adhesive?

 

it doesnt adhere where the tape is but adheres every where else. it doesnt have to adhere to every lil inch as long as it is pulled taught. u are using headliner material right? it has about 1/4 in foam backing? this is the way ive alwys done them in my shop. any more questions let me know

 

yeah brand new headliner material with 1/4" foam back

 

You could always put some foam backing material in there to fill it. The way I do mine is to use 3/8 inch padding glued to the repaired headliner, and then stretch vinyl over it, tight, then staple into the fiberglass.
