insert trim panels

velcro?

dome snaps?

are you wraping the panel in vinyl or carpet? if you make it a very snug fit so the wraping holds the panel on..a little bit of velcrow may help too..

also you couold go to a boneyard and pick up some spring clips off a door panel and attach them to the back of the panel...drill the right sized holes in the right places and you would be able to push the panels in..it will be tricky to get them back out if they are painted though and you dont want to risk the finish..

Yes, it would be painted. I just need something that can be removed if needed. i will not be removing the insert panels often, only in cases where i need to access things behind them.

A good example of exactly what i am trying to do is the new Sinister 6 demo car by alpine. The car has insert panels all over the place. Some are permenently bonded on, others are removable to access the various wiring/controls behind them. My design is not as complicated as theirs, but it is the same exact idea. I just cannot figure out how to attach the insert panels while still making them removable.

What are dome snaps?

i use serated panel clips and glass them to the trim/insert panel.  When u are finished the main piece all the way up to the primer stage, tape it off and make your trim piece (or however u wanna do it) then when u have about 2 layers cured remove the tape, place the panel back where its supposed to be, then drill through both the trim/insert as well as the panel you're attaching to (test various hole sizes by drilling into a scrap piece of fiberglass or thin hard plastic till u get the size u want...different hole sizes will make how easy or hard the panel is to remove).  Once the holes are drilled insert the serated panel fasteners and put 2-3 layers ontop of that, then do the bodywork and prime.  Keep in mind though how u want to remove it, u can either make recessed sections and use a plastic pry tool to pop out the insert or u can make it so u can reach from behind and pop the panel out...just make sure u have a way to remove it, lol.  Hope this helps.  I've also done a snug fit insert but not with fiberglass.
