ok so i have made a fiberglass copy of my panels and rear deck cover and right now they are only 4 lairs of fg because i still dont know were i am gonna put the subs and speaks so now i am going to put a lair of bodyfiller/fiberglass so that i can prep them for install and i was just wondering if i have to prime the panels before i paint them or can i just paint them? Also i am doing all my work at my work shop and the sanding dust is starting be a problem so i was wondering i could wet sand the figerglass to prevent the dust.

 

Yes you should primer as the primer will fill in most of the small pinholes left in the bondo and you can wet sand but it will take you alot longer that way.

 

DO EXACTLY AS selective sound told you, it works. I tried it before

 

what is better to use on a plastic bumper cover...
boondo or fiberglass
(both are the kinds you can pick up at crappy tire)
which one will stick better and crack less if a rock hits it...?

 

Neither will really hold long on plastic, there is a two part epoxy that works great on plastic. Call up your nearest napa and they will set you up with what you need.

 

how much is that roughly?

 

Not sure on price but I think it will cost around $90.00
