custom Bondo body work and bumping

[nick585willey]

okay so heres my question. lets say my car has ALOT of body filler/ Bondo because of shaved door handles and rear windows.... does anyone know from experience if i put a LOUD CAR AUDIO SYSTEM into the vehicle if i run the risk of breaking apart the bondo??

Were they shaved properly? By properly I mean welded metal patches with filler used only for final smoothing, no thicker than 1/4". If so, then you'll be fine. However, if it was done incorrectly with excessively thick filler, or filler used over holes with no backing, then you may have issues, though if it's been done poorly you'll have issues regardless of what sound system you run.

yes it certainly was done the right way! i just worry about it i mean if i spend like 6 grand on a paint job and then put a system in it i dont want to mess up my custom work! the only other downfall is where the rear windows were taken out and new metal was welded in the holes..... it looks kinda funny on the inside with no windows and just metal there, i mean its coated with spray on lining but im wondering if theres anything i can put there to make it look nicer!

Fabric like a headliner.

Make it a speaker location and make an enclosure to fill the area where the OEM plastics curve in towards the window. Make the enclosure with mounting tabs and thin foam backing or sound deadening to prevent rattling. Then mount them using the window trim to center it. Once its centered hold it in place, remove the window plastic by sliding it down your arm that is holding the enclosure. Mark the enclosure. Then drill and mount the enclosure and replace the window trim.

that is ingenious! great idea! omfg! motivational speaking right there haha! i think il go a step further and make it custom fiberglassed! will look nice!

I meant fiberglass, as wood would not be ideal or small enough to work with in that area. or make them CF!

You better follow up with pics and a write up!

 

[nick585willey]

oh absolutely! im gonna have to a bit of measuring and research before i attempt it but i should be able to do it with no problems!

 

[DSM_love_GST]

No, slowly shave blocks of foam, until they fit snug!

 

[nick585willey]

and then what encase the foam with fiberglass or what im not used to trying to actually FILL a space with a custom build! i mean as far as making an enclosure for a system thats no biggie but this is different

 

[DSM_love_GST]

Yeah, once its snug, shave it a tad to compensate for the fiberglass and resin. Then line it up as you would to mark the placement. Once it is up there hold it or tape it up and measure for the mounting tabs that you will fiberglass into the enclosure.

 

[nick585willey]

now after i get it all ready to go in and what not what do you recommend i fix it in place with just self tappers?

Metal tabs

 

[nick585willey]

so like use fiberglass resin to connect tabs like the ones used to fasten mesh onto body kits???? im confused where would these tabs fit into? like behind the plastic?

 

[DSM_love_GST]

you fiberglass the enclosure. When is dries, use metal tabs with scored ends and fiberglass them in using the measurements on the side closest to the window.

 

[nick585willey]

brilliant! you are one smart man!

If the surface was properly prepared before the application of a body filler then it should be good to go. I agree with post prior that stated the proper way to to a shave is by welding and using a thin amount of glaze to smooth any imperfections out. It really is all dependent of the kind of system you are trying to run in the vehicle. Thinking realistically here a basic assumption that could be made is, if the system is loud enough to start cracking the body filler wouldn't it crack my windshield or "hatch glass" to. Your going to need a lot of power to start blowing filler off of doors, unless a 16 year old auto body stundent wiped his friends car with body filler, or you took it down to MAACO and let them cave and pave up your entire car's side.

Student* appologies.
