bumper filer help

[denn454]

i cracked one of my fiberglass replacement fillers a while back. At the junk yard i found 2 perfect origional fillers that were still flexable, for $2 a piece so i get them home and tryed using a chemical paint stripper on one, the side i don't need just to make sure it will work and it ended up bending, i dont' know if its just from me holding it and it fel over and hasnt' straightend out yet, or of the chemical did anything to it.

so on the other piece i used a scotch bright pas on a die grinder and tryed to take off the paint. it got the paint off, and some of the plastic.

so now i have one warped one, and one filled with little roun gouges. i can probably bend the one straight, and once its on the car i dont' think it will be a problem.

the other one is going to be a mess. body filler would easly fix the gouges, but since its rigid will that give me a problem? is there something that works?

its a little late now but what works good for stripig the paint on them?

1st was fillers factory paint or painted over ? if factory sand with 220 w/d paper just to scuff and 10%flex to paint and spray. if painted over never use stripper will soffen plastic filler 220 and up w/d paper or you will gouge material as you say you did use 220 with water keeps plactic cool and go up to 400 w/d

You can also strip these using plastic media blasting. Look in your local yellow pages. Just about every large metropolitan area has someone that does this. And its affordable too.

i learned the hard way the stripper softens the plastic, i've got to straighten it back out or get new ones now. I only striped one with chemicals. the other i used a scotch brite pad on a die grinder, i thought it would be soft enough to not gouge the hell out of the plastic, but i was wrong.

I can strighten the one i used chemicals on out, thats no big deal. i'm worried aobut the other one, the one i really need anyways. what kind of filler can i use to smooth it out? sanding it all flat isnt' an option.

THANKS, and this is proof why you shoudl ask before doing someting you know nothing about.

bumper filler repair

First because of material and location they will flex to much for body filler of the normal kind. Go to napa, kragens, autozone, what ever your parts outlet is, look for Vinyl Bumper Repair kit. Comes in a tube, over fill your gouges then it let it dry a couple of days. Put your filler over a wood block this stiffen the filler,with a DA ,Sanding Block, Jitter Bug, what ever you have take 400 grit wet and dry paper with the key word being lots of water ( lots) sand your high spots down, when close go to 600 paper and sand the whole filler bring down your high spots level then you go on from their hope this helps.

On the same subject of the fillers, I noticed that after my car sits in the garage for a week or so, all the fillers get a chalky film on them. It wipes off with a rag easily and I've tried waxing them with no good results. It's not a big deal, but it is irritating. Has anyone else noticed this?
