xtremekustomz- Yeah, just explained such stuff to a guy on the Crown Vic forum, hopefully saved him a big disappointment.
More Qs, since I really appreciate your expertise:
What filler do you like over the epoxy?
What primer do you like on such pieces?
I doubt I`ll ever do *any* more paint/body work other than some undercarriage bits, but I still like to know about it.
I will be using evercoat polyflex on this bumper and any bumper for that matter since it is flexible. On this bumper I will be using an epoxy primer from southern polyurethanes. I`ve heard some other epoxy primers will bubble up. I wanted to be safe so I ordered from the guy who has restored a lot of them. On a new raw plastic bumper i will wash it and then use a grey scuff pad with scuff paste. After that clean it with a waterbased cleaner, spray adhesion promoter and seal/base/clear. Pre primed bumpers it just depends. Usually it`s best to wipe the primer off if possible. I`ve had adhesion issues painting ovwr that factory primer especialy the cheaper aftermarket parts.
xtremekustomz- Heh heh, we`re educating each other
Gonna post the Epoxy/etc. info on a Crown Vic forum, another guy is interested in such work and he`s getting, uhm...advice I consider unlikely to work out.
Started on the hood today. Took around 6 hours to sand the red finish off with some 180 on the DA and then with a paint stir stick and fingers on the vents. I think it took around 3 hours to do just the vents.
Just a FYI with the vents on the hood. I use to use the wire wheels in a drill which really cut down the tedious routine if your interested. Just wear safety glasses.
Looking forward to the updates! I enjoy following your work! Would you use the 2-part epoxy on any modern bumper repair as well? Also can you explain why you mentioned about not using an adhesion promoter for the `bird but in the future you would use it as part of your routine for new bumpers? Does it have something to do with the combination of the epoxy repair and the adhesion promoter?

I always use adhesion promoter on new raw bumpers. If not the paint will peel. The firebird bumper is actually made out of tire rubber so it is a completely different makeup than the plastics used today. I wouldn`t necessarily use an epoxy on a new bumper. Most of the time you can get by with a grey pax with scuff paste and wash. After that adhesion promoter, sealer and paint. There is a company called urethane supply company that sells a primer that all you do is wipe the bumper down with a waterbased wax and grease remover, dry and spray the primer. I know it works well with toyota a bumpers. After sprayed you can paint it at any time down the road without sanding if need be. Plus it is very durable.

xtremekustomz- No worries about any sanding artifacts showing up later?
Nope. This primer doesn`t shrink. The initial 180 was covered by the slick sand which is a polyester primer surfacer. It was then blocked again with 180 and covered with the kd3000 high build primer surfacer. You can actually prime over 80 grit filler scratches with it. I like to leave the parts in the sun for a while to cure as well. I`ve been told a day in the sun is equal to a week in the shop.
