so ive been working on a new fiberglass subwoofer box. it is my first one with no experience and so far it is going pretty well. ive managed to build the box for the 2 12" woofers, did 4-5 layers of fiberglass and 2 layers of bondo. however i find the bondo i am using (red can from part source) is really thick and im finding it really hard to get the smooth finish you see on all fiberglass box's. even after hours of sanding and grating.
is there a finer or thiner type of bondo i can use for a "final coat" to get rid of the last pits and odd spots?
i picked up "ultimate detail bondo" but im not sure if thats what im looking for.
