Fiero Paint and Body (Page 1/2)
KZ88 JUN 18, 05:47 PM
Hello all, It's been a long time since I've posted on here. I've got an '84 SE now, I've rebuilt the motor, converted the headlight motors to the 87/88 system, changed over to the larger fuel tank out of my old 88. Long story short, I've had her around three years, she runs great, I've driven her all over the place, and she's got very little rust on the frame (She even still has the original battery box). I work as a mechanic professionally, so all the mechanical and electrical stuff is no big deal. The part I'm unfamiliar with is paint and body. Most of the plastic and smc panels are in pretty decent shape, but there's some scuffs and dings that go into the material and one crack in the door panel that I'm gonna need to fix before I finally get around to painting her. So my question is: what should I use, and how should I go about fixing this? (I'm thinking Evercoat SMC Resin, but again, this is all new to me.) And then, once I have fixed these issues, what do I do to prep the panels for paint? And what type of paint should I use? And where can I get new seals for my luggage rack, which I'll have to remove to paint the decklid?

This picture doesn't seem to have attached correctly to my first post, so I'll try again here:

For the repairs on the door I would shy away from anything fiberglass or non flexible. I think 3m 4240 is the number. It’s a semi rigid urethane repair since the doors are urethane. As far as the cracks in the smc they make a 2 part smc repair as well. I can’t recall the number off the top of my head.

I'm a little more concerned about the upper hood and roof from your photos. It appears the SMC fibers are coming through the paint. That's a little different to repair and prep for paint.

Yeah, those are the parts that I'm really unsure how to proceed on. Like, do I just build up SMC resin over that, then sand it down to the correct appearance? I'm just not sure.

Thanks for the recommendation on that. That 3M 4240 looks perfect for the door.

Thread bump. Anyone have any ideas how best to handle the parts where the SMC fibers are coming through?

The best way is with an epoxy primer. It's thicker than standard primer and will fill and seal the surface. It should also prevent any future issues.

If the SMC fibers are open there is moisture in the SMC.
Before effecting repairs, keep the car in the sun as much as possible to drive out the moisture or it will blister later.

I would replace, not repair, the door skin.

Why not just replace the panels? These parts are still very common, and generally don't wear out. Just grab new skins/hood and call it a day!
