I'm either getting a 00-02 lip or an LS Sport bumper and going to add to my 99 z24 front.
I've done the 00-02 headlight swap and have a 00-02 bumper i can cut and either weld or fuse to the top portion.
So the headlights sit right with the bumper.
My concern is I've never welded or fused anything before and wanted some tips.
I'll try one of these on some extra abs pieces i have til i get the hang of it but need some advise.
Anyone have and tips they can throw my way? thanks

well, its definately going to be a tough thing to do. i would suggest looking into 3m panel bond or Fusor
If you have CF engine bay pieces, SELL THEM TO ME!

I'm really thinking of putting the top of a factory bumper on my IF, because I like the dip the factory bumper has between the headlights.
If you do cut yours up, wanna send me the top of your 99 bumper? 
i thought it was a bad idea to put abs and fiberglass together??? or is your front urethane?

IF front is urethane. and it is a bad idea to mix glass and urethane. the fiberglass will expand/contract at a different rate then the urethane causing it to seperate.
dont get me wrong, it can be done, and has been done, but ive never seen or heard of this method actually lasting

once again the bumpers are not polyurathene!!!, or abs!!! the 1st thing i can tell you is this identify the ytpe of plasatic it is, you should see this TEO, TPO, TPE, PP
plastic welding is a time consuming process, and takes allot of experience, but i will give you tips and the products to you use
both sides need to be lightly grinded so the weld sticks, now the kit comes with all types of plastic rods so once the plastic is idnetified you the appropiate plastic rod
my welder cost me 225, so this is not a cheap mod you want to do
ok so anyway, i suggest using 3m panle bond on both sides of the bumper, and use the tpo repair material, and it needs a adheshion promoter as well because it is a oflien type of plastic, then ya need the gun for the 3m tubes
bondo, fiberglass does not stick to plastic doing what you want to do only use plastic repair material

ok click that link that was for a friend of mine of his olds and that plastic was a offlien type plastic, the middle part was plastic welded in and panle bonded on both sides and the rest shaped with a plastic repair material
this is not easy so take your time
can i haz bondo
what about Lord Fusor products?
of the TEO, TPO, TPE, PP... which is the stock 99 and stock 00 bumpers made of??

ummmm ok dad, its not poluyurathene when plastic is learned it can be shaped and molded to allot of different shapes, the repair material is there for a reason, experience in plastic is the key, nothing else

This is good information, and it's exactly what I've been trying to find out. I've seen a few posts looking for help on repairing stock bumpers, and no one has given this type of info. Most of the time it just says something to the effect of "fixing urethane is a pain in the ass, and doesn't usually hold well", and lot's of people have given advice on bracing it with metal, but I figured that some kind of plastic weld was the way to do it.
BTW, no need for the multiple exclamation points.
The reason no one posts a "how to" on repairing stock bumpers is because it IS a pain in the arse... it's a pain to do if you don't have experience repairing plastics, and a pain in the arse to explain it in a way for everyone to comprehend. Believe it or not, repairing plastic isn't a "novice level" job
i hear ya fallen angel
from the researching that i've done so far, i've found out that.
but my issue is combining. and while that can still be considered a repair, i just need a solid line of two bumpers to connect.
i'm still going to read up more on it and practice on smaller, extra pieces that i have. so i don't expect this to be a quick and easy job but achievable

Oh i know
my comment was more directed at Quiklilcav. Good that you're going to use smaller extra pieces and do research... it'd be nice if more people did that instead of just diving in and such
Good luck to you!
what kind of plastic welder did ya get??? i taught my self on bondo spreaders and old bumpers did ya get the gun, and did ya get all the repair material and adheshion promoter
can i haz bondo
haven't ordered anything yet. i'll probably order two different brands and try out on some side skirts that i have laying around.
i figured that i'd need an adhesion promoter too so that will need to be included somewhere. gotta finish some projects first before the 95-99/00-02 bumper combo though

i watched a modern marvels last night on welding.. they showed how plastic welding is done. pretty weird actually, a lot of it was done with sound waves vibrating the material so much that it causes major friction and bonds the stuff together INSTANTLY.
but i doubt this is what you guys are using to weld with... is there an actual welder type like a mig or tig etc that you have plastic wire that comes out insted of steel or something along those lines??
also... paul tjepkes is making me a custom 95-99 z24 front bumper w/ a 03-05 lss front lip molded to it. his plan is to mold it on using fiberglass. so, plastic-fiberglass-plastic. does that sound like it wont hold up? or should i honestly just get the lip 'welded' onto the bumper?
he shouldn't mold it using fiberglass. i was gonna do the same but now i'm gonna plastic weld it or fuse it.
i'm also going to get the 03-05 ls sport lip/piece added to my 99 z24 bumper with the top portion 00-02 for my headlights

fiberglass will not mold 2 plastic pieces together... it will not hold, they are not the same substance. Now if you were molding a fiberglass bumper to a fiberglass lip, then yes fiberglass would be perfect.
correct, why is it sometime its like we type and no one sees our posts no one wants to see the advice from a girl or a 15 yr journey man iam shocked lol iam appled lol
can i haz bondo

thats exactly what it is. oh and i hate plastic welding. thats what we are doing in school right now and its not very fun.
i persoanlly love repairing plastic they call me the plastic man at work

well what about molding a fiberglass lip to a plastic bumper? because ive personally held a bumper like that in my arms and the lip was on there for good. it wasnt moving, flexing or otherwise.
