What stripping products should I use/NOT use to remove unknown primer/paint from "old School" OEM
GM fiberglass spoiler ? With Curvy surface using a DA will be difficult if not impossible ???

Blasting ??? Chemicals ??? Hand Sanding ??? Wet Sanding ????

Thanks for the education and patience

Just my 2c.....hand sand only with the biggest grit possible( around 80) until most paint is removed...finish sanding with 180.... Epoxy , fill, epoxy seal, top coat...I personally would never run a DA on a small , curvy surface. If previous paint has good adhesion, it ain't all gotta come off
 
still seeking advice
AM looking for vendor my area using walnut or plastic media

Anybody have experience using KLEEN STRIP Aircraft FIBERGLASS stripper
$36/gal at my vendor ???

I used it on a spoiler I painted a few months ago. No issues so far.

I have used strippers such as 3-m safest stripper & others on fiberglass years ago with no future issues. BUT on an item like your fiberglass spoiler, it ain't that big & rough handsanding with the proper blocks could be an advantage timewise in getting it better than factory made it.
 
I would think you would be better off not using chemicals on it. I agree with jcustomz that block sanding would give you a better looking finish.
 
On the two end pieces (71-73 Camaro) I wound up using a BLUE 3" Scotchbrite Cookie
on a Harbor Freight $12.00 air motor..........
The LONG center portion (bolts to deck lid) I'm using a DA with 100 grit and 180 paper
by hand..............
Need to read and learn which primer and build primer for fiberglass ????
 
I'd use a few different types of rounded sanding blocks by hand for that using long cross hatching motions. One of my rounded sanding blocks was made from cutting the plastic caulk tube outside off of an expired tube of silicone rubber. You are not going to get a straight looking finish from machine sanding those shapes of parts.

For a base primer, definitely the SPI epoxy to lock things down. For a thicker build primer for such a use, I generally like a sprayable polyester primer like evercoat g-2, but with the costs of it rising so much these days, me & some others have started using spi turbo primer instead.
