  • What filler do i use?

    i am working on making my taillights, and have gotten to the point that i need to fill in the gaps between the clear lens, and the tail housing.

    the gap is about a 1/8" and is about the same consistent size gap around both lenses

    on the back of the taillight, it says:
    L: PMMA
    B: PC+ABS

    so i believe that the rear housing part is ABS, and uses polycarbonate red lenses, but the front lens is a variation of plexiglass(even though it is a kiddy link, it describes it really well!)

    here is a pic of the housing i am working with, and a pic of how the project should look once it is done:





    before really looking at the lenses, i got a bondo-brand bumper repair kit, thinking that it was flexible enough to cope with the plastic parts, though i am starting to wonder if there is a better product out there for this..

    any ideas?

      sorry, i need to fill in the 1/8" gap between the clear outer lens, and the silver-coated plastic housing. the housing is ABS, and the outer lens is a variation of plexiglass.

        Okay, so in the picture, the clear lens has just not been removed yet? The lens will not be a part of the job? That's what is confusing me

          i was planning on keeping the clear lens, and just filling in the gap.

          the 3rd picture was done by a guy that works at his family-owned body shop-- he claimed that he used bondo to build up the lower plastic housing to the same level as the lens..

          i have plenty of bondo to repeat that part, but just think there is a easier way by using the existing lens as part of the build..



          a little more explanation--the second pic shows it the best.(the larger circle is complete, and the smaller circle has not been cut yet)

          the original layout for these lights is that the clear lens goes over the entire taillight. i am cutting out the section of the clear lens that is over the red domes.

          i need to fill in the gap between the outer-clear lens, and the base housing(silver part)..

            ahh

            I got cha,

            Are you able to remove the red light so it will be easier to fill and sand.

            I would recommend sandingiwht 60 grit before body filler

            get some evercoat fibertech body filler then some regular lite-weight filler to top it off.

              I'm not sure that a standard body filler is your best choice based on you mentioning you think you are working with ABS, you might want to give some Evercoat Polyflex a try. I have a bottle here but I have not tried it yet. It is very expensive but I am told it is amazing stuff. This is primarily used to repair bumper shells with (I am told) great results.
              Here's a link to some info. By the way, friends don't let friends use Bondo, try some Rage Gold by Evercoat sometime, it will make you very happy

                It just a glaze, it won't build up like you need it to.

                  thanks!!

                  it sounds like a much better solution then bondo

                  is there anything special i should know, or does it apply/smell like bondo?(i kind of expect it to smell similar, but if i could do most of the work in my basement, it would make everything easier..)

                    i am kind of new to the professional approach to parts work like this.. what light wheight filler do you recommend?

                    i have heard of rage gold-- mostly from car audio how-to's on building a fiberglass box, but never used it.. would that be a good light weight filler?

                    after reading the description of the polyflex i am not so convinced that it is meant for this, as i will have at least a 1/8" of standard filler there--


                    Poly-Flex™
                    A flexible polyester glazing putty designed for spot filling and skim coating over repair areas on flexible bumpers and plastic parts. Its flowable viscosity is ideal for filling minor imperfections such as sand scratches, nicks, dings and gouges. Poly-Flex™ may also be used to skim coat over repair areas or large surface areas that have the original paint still intact. Blue cream hardener included.
                    it seems like it is meant for very minor imperfections, where i will have more major imperfections


                    i am ready to order now, just need to know what i need!

                      polyflex is just for minor fglazing, pin-holes, etc.


                      get yourself some fibertech and then some glazing in a smaller tube to save some$$

                      Just get these two

                          Don't forgte to rough it up, that fibertech is good stuff and will give you the build you need

                            That looks like a good solution, I'll be interested in your results! I just didn't want to see you use a standard body filler, it would likely crack pretty quick.

                              I'd def go with Nexson's suggestion.

                              As for the tips I'd say don't think your going to get the fibertech perfect with the spreader. Err on the side of too much. Then get a rough grit out and sand down past a bit where you want the finished layer. Then when you're applying the glaze coat, thats where you get a bit more detailed with the spreader. I'd use and old credit card or something with a rounded corner and use that to apply the finish glaze in the corner where the lens meets the wall. Again, slap in a bunch of glaze then use the rounded corner to squeegee it in and remove excess as you go around. This will make for a uniform bevel and you wont have to go too much sanding after that. Maybe a 150 then 300 and your good.

                              I've seen your light mods so i know you have the patience for this. You'll be fine.
