question for anyone experienced w/ bondo/glassing

[95mx3]

im experienced w/ glassing and bondo work (mostly dashes and interior pieces) although i was wondering would i run into any problems down the line, if i just did a coat of filler(bondo) and finishing cream on interior pieces such as the MX pillars up to the headliner?! when i do dashes and systems i ALWAYS put down a least 2 coats of glass then (1)bondo, (1or2)finisher, (1)primer, (3or4)paint and (2or3)clear. although since there isnt really any pressure on those pieces (also glove box and piece that goes around gauge cluster and down to head unit) can i just get away with no glass? lemme know guys! thanks!!

you can definitely try, although glass over it would be best first, if youre putting filler on it, rought up area real good first so it etches to it

id greatly suggest putting glass down first just to be sure it wont crack. better to do it the first time, far easier to work with now than later.

yeah.... ive been doing my friends pillars and interior pieces such as that with what i said above, 2 coats glass and so on. i was just wondering if i could cheat (successfully) on it. but like u said better doin more work now rather than later!! thanks for your advice guys!

This is a bit interresting, Ive read somewhere in one or more of the fibreglassing howto's that you shouldent resin fibreglass onto plastic because it would be very brittle or crack or something because the wouldent adhere to the plastic...

So you guys are saying that you can put fibreglass ontop of the MX's A-pillars??

[lakersfan1]

What are you looking to do? Bondo and fiberglass don't stick as well as most would like to plastic. There are sandable plastic fillers you can get you know. 3M and SEM both make sandable plastic fillers that you can pick up at pretty much any auto body supply store.

Were you asking me lakersfan1? Im going to put my tweeters in the A-pillars to get the best sound but need to mold them in nice...

I read somewhere that fibreglass wouldnt stick well ontop of plastic, so i was hoping it would bond better with speakercloth because its so thin and stretchy..

Got a better idea?

To get the best sound your tweeter should be no more than 6" from your mid-bass driver. Having it up in your a-pillar will greatly raise the sound field as well as make the high pitched frequencies be the first thing your ears hear... If you want proper imaging keep them low by your driver, if you want your ears to bleed put them high so it's the only thing you hear...

Its not a problem theyre high quality speakers, and i can dampen the tweeters by 3 and even 6db in the xover i believe so that should be more than enough..

Allso best audiofile sound is when tweeters is in earlevel height and farthest away so the left/right difference gets minimised, just have to raise the mids as much as its possible and then angle them good

Yeah. Enroll in a Hooked On Phonics class. I just wrote an answer, and yet you're still asking.

[DJsMX-3]

Maybe youre just stupid or something? I asked if it was me that you were answering..

Since your answer maybe wasent meant for me and you didnt know i was thinking about resening speakercloth on it, your answer didnt apply to my situation
