Just wandering what the best way to fill two holes from spoiler!!
I lowered and moved the factory spoiler back and need to fill the two holes from the original
location!!

I've never done any bodywork, so just looking for ideas and what products to use!!!
Also would like to fill the antenna hole in front fender!!

Thanks,
Rick

They make a patch kit for SMC panels. It works just like fiberglass but made for SMC panels like the ones on a Fiero.
You can pick them up at local parts stores. Just fill/patch, sand, prime, and paint.

Rick,

You and I talked about this, and it sounded like a good idea. I'd like to see a pic of it mounted on the deck. Holes not a problem!

You ever see those fiberglass repair resin cans at the autoparts store? Thats the stuff and the white cloth, cant forget the squeegee, sand papers, primer, top paint and clear coat.

Rough up the inside of the panel behind the hole.
Cut 3 patches of fiberglass cloth to patch hole plus 3 inches around extra.
Mix Resin and catalyst
Squeegee the resin for the first layer being sure to get it all over good
Place 1st patch into the wet resin
Repeat for the other two patches being sure clothes are good and wet
Allow to cure
Trim extra cloth away
Mix resin for front side
Apply in multiple layers to fill hole to exceed level with the rest of the panel
Sand with coarse paper to get into general shape of panel
Use finer paper to fine tune shaping
Use 220 paper as final rough
Prime with primer designed for flexible panels
Continue with 220 to refine as the flaws will become easier to see
Final primer application
Use 400 paper to smooth the primer
Wash panel and use tack cloth to remove dust
Use Glossy paint designed for plastics and apply 2 coats
Clearcoat with Urathane coat for 2 coats
Allow to dry 2 months
Refine surface with rubbing compound/wax

Am I missing anything anyone?

Oh yea remove the panel from the car first.....

Dont use fiberglass kits from the parts store !! Fiero panels are SMC and Polyester resin will let go over time. You need a resin that is SMC compatible from a body shop supply if you want it to last. For the anteena hole on the RRIM plastic fender you can talk to the body shop supply about the two part flexible epoxies for plastics and patch the hole with another piece of RRIM.

Or just use plastic plugs for now. It doesn't look too bad unless it is a show car. You can touch them up with a small body of body color paint. You would probably be the only one who notices!

lord fusor makes a great product for repairing all plastics. 2 part, very easy to use and prep for paint. check your local QUALITY parts store. They should have it

You need to "V" out the holes from the top. I use SMC repair from Fiberglass Evercoat for the SMC (mix in some fiberglass mat chopped up with scissors), & SEM makes a product for the RRIM (fender).
Do a search & you'll find several threads on the subject(s) with detailed instructions.

errr My Factory Manual says to use the Resin and Fiberglass...... Which I have done on my car....You say it will seperate?

I used fiberglass and resin filler and worked fine for me.

Way back when I first got my Fiero I read in the factory manual that regular glass resing was to be used also. I deleted my trunk key cylinder and smoothed it out with glass. Lasted about two years before I could see a crack all the way around where it let loose. Next time I went and got some stuff made for Corvette SMC panels, Pricey but its been holding 8 years so far. Guy at the body supply house explained that for production on SMC panels at the factory SMC resin is used because it has mold release agent "built in" so they fill the mold under pressure and heat cure, but the relese agent remains and make it difficult getting repairs to bond well.

would bondo work?

No Bondo !!! Bondo ULTIMATE will work for small non structural repairs, it is made to work on SMC but not regular Bondo

This is what I want to do so i could always go back to a spoiler later. I wanted to use rubber plugs, but did not find what I needed. The closest thing I found were rubber bumpers designed to be put on a hole in sheet metal. Similar to the little bumpers that the headlight doors come down to rest upon.

As I did with mine, having taken off the existing luggage rack and knowing that, sometime in the future, I can deal with it "properly" when I get it painted. The plugs are a plastic "christmas tree" style meant for trim panels.

I used the little assortment pack from autozone. I think it was $5. Then just used a dab of black rtv from the inside to seal it up.

Like Driver said, use filler for SMC. What I do is ' dish ' the inside AND outside of holes (like this > < ) , put tape over one side and filler on the other. Then pull off tape when dry and fill that side too and it wont fall out because of the barbell shape. If hole is big enough I use a small piece of fiberglass matting larger than the hole and put on the inside while the filler is soft, and more SMC filler over it. The SMC filler will soak into the fabric just like the resin does.

Thanks for all the information!!!
Will get a pic posted to show the new spoiler location!!

SO, afterwards is there a way to spot paint, or does one need to paint the whole decklid?

I plan on just using some touch-up paint!!
