fiberglassing for looks

Im wanting to make my box look fiberglass comsetically. What will i need. The box is already built

the box is mdf i assume, one way you can do this is to first round your edges on the box,then scuff the box up with some 150 grit sandpaper. next apply a thin coat of bondo to entire thing,then sand with 80 grit and a hard block,then 150 and a hard block,then 220 grit. any imperfections you find in the box can be fiixed with finishing putty. if you dont have much experience with sanding I would use a guide coat in between sanding grits, and sand starting form the center , only sand at angles (\)(/)in an x pattern sort of way. then prime the entire box with high build primer, guide coat it,then wet sand it with 320 or 400 then 600.now it will be smooth like the fiberglass "look"and its should be pretty close to paintable if you need know how on that just pm me P.S> on the primer first coat:light second coat medium wet third coat: medium if you block it out and cant fix a blem with finishing putty you can reapply primer to an area and block blend it in.-A vision without a plan is just a hallucination-

Yea, i was wanting the look. I dont car about the paint. I was plannin on doin bondo and all that to it with one of my friends. His dad does body work so he could help. I just want an amp rack so that my amp looks flush mounted and add some rings to the subs and make them look raised and maybe cover it with some vinyl

if your going to paint the mdf make sure you seal it first.Dustin Rockney

d-rock-81 There would be no need to "seal" the mdf becuase there would be no mdf.It would be covered in bondo and primer.You do not have to seal the primer but I would recomend it if your spraying a really light or really dark color. as for the look you want pcana11, if you are going to wrap it in vinyl then theres no need for bondo just round your edges and corners and add your rings and amp rack then wrap it if its covered in vinyl your not going to see the f/g look any way except for the edges just round them like I said and you should be good to go .Dont waste your time with the bondo and go to a cabinet shop and ask them what they use to round edges , I know they use a special tool that is quick and easy.-A vision without a plan is just a hallucination-

that depends on how much filler you use. a light coat is all you need to fill the little gaps, then block sand and some wood will probably show through after so sealing it will not hurt. now if your just gonna glob on a bunch of bondo and sand then go to town i guess....Dustin Rockney

if you were going to seal the mdf you would do it before any bondo was applied not after because wood sealer can and will contaminate bondo and primer. you would not just glob on the bondo as you say but you would put enough on to not show mdf except in a few places that would make no difference in the end result. Also if you did seal the mdf before the bondo the bondo would have a harder time mechanically bonding with the mdf.-A vision without a plan is just a hallucination-
