Calling all modders ...
I found a solvent that will "eat" cured silicone. However, smallest size is 5 gallon bucket and is $325 plus $57 shipping. I'm checking if anyone is interested in buying-in for a portion (relative to how much you want) to offset the cost.
I've been experimenting with opening 04+ headlights and it's possible to manually remove the silicone (would take forever though) or a quicker way is to cut some bits off to get easier access to the silicone (but I think this would compromise the strength of the lense).
I think the best & proper way is to use this solvent. I will most likely do this without any takers anyways but I figure I'd ask. When I have my original OEM Bi-Xenon, adaptives opened, I'm going to paint or mod the amber lense similar to the euros - then sell them since I have the euros already.
So, if you always wanted to open your 04+ headlights to mod them. I'll have the stuff to make it a WHOLE lot easier.
