I just finished a fiberglass sub box for my 2001 Mazda MP3 (coincidence?) Everything went smooth; the structure is solid, sounds nice, fits like a glove. I have everything i need to paint it and I would like a piano type finish to it. I have sanded it down and primed a couple spots. For the most part, it looks lumpy? or wavy. I have applied some body filler to certain areas, but i think i did it wrong (applied filler, dried, sanded it all off until only little holes r filled, plus i used an orbital sander) What is the correct method of applying body filler to smooth it out and get rid of the waves and lumps?
No announcement yet.
new to forum, couple questions about my fiberglass box...
