A little bit ago i got into an accident and i just got the body pieces yesterday...(fenders, hood, bumper) now they are all black but i was wondering are they ok to jusst put on or do i need to get them painted before putting them on......ithnx

 

If the parts are new replacements, they come coated w/ factory e-coat, primer. They should sealed when painting too. Yes, the parts need to be painted before exposed to the elements.

 

No they do not need any primer. Clean it, Sand it, seal it, paint it.

Isn't sealer a primer?

 

Some what, some sealers promote better adhesion, some are design to stop bleed through. It stops bleeding colors from interfering with graphics and artwork. Almost the same characteristics as a primer. Primers are more used on body filler, a coating applied to a surface to prepare it for paint or another coating or adhesive.

 

yes seal that up, it will help against rust protection and it will prevent solvent popping that might occur from the primer, if you spray primer.

 

you have to spray sealer when u have factory parts with primer already?

 

i usualyl scuff them w/ a RED 3M pad and then primer block it wet and then paint, but thats jsut how my fathers done it so i do it that way too,

Yes, it's industry standard to seal metal outer replacement panels.

 

You will give yourself a headache if you do not seal the parts.

 

what about panels that are already painted, just 3m RED scuff pad and then paint?
or should i lay sealer first?

 

Red scuff pads are great but I wouldn't prep painted outer panels for a refinish with them. They are coarse and could cause sand scratch problems on a soft clear type surface when painting metallics. Also they will not level the surface peel or minimize imperfections. Abrading w/ sand paper is the way to go, but for edges, inner, undersides of parts they do work good.

Sealing is good but not always a good option. It takes longer, more material is used, more material on the surface. Complete base coverage, over a flat surface, applied correctly will allow you to clear the part w/ minimal surface peel. More material under the clear thats not needed will contribute to surface peel in the clear. Not every paint job is completely flat sanded, crazy baller style. If you prep correctly, quality paint will adhere very good and last long assuming everything else been done right, without sealer.

u can use epoxy primer over scuffed metal, then just tack it and go straight to paint. thats what i did when i painted my friends OEM bumper and fenders new from fatory. epoxy promotes adhesion and seals. same stuff honda uses from factory

 

just scuff the ecoat,tack and wax and grease,lay down a few coats of primer,use some guide coat,wet sand with 400grit,wax and grease agian then tack then base coat..

There's really no need for filler primer and wet-sanding. Just scuff the new panels with a red 3M prep pad, clean well, use a primer seal, base, then clear. Sometimes the texture is pretty bad on new panels (most times it's not) and you may wan to DA with some 320.

 

I can see if you need all parts to be in primer for some reason, or accepted w/ damage, but other than that its pointless to prime, block something thats already lazer straight.

 

yea no primer, unless its epoxy, I use epoxy because the paint will stick better, but lay a VERY light coat, then tack and base. its just an adhesion promoter/sealer, u should be able to almost see the ecoat underneath
