Silicone covered HL

[Chips be-gone]

Hello folks

I have been doing H/L's for about 4 years and I came across a set that blow me away...

I was doing some cars on my car lots and I came across one that got my goat and I am wondering if you all have ran across a set that has been treated with a silicone type coating? I was working this set for almost 3 hours with no luck. I use Dvelup, and as soon as I sprayed the Yellow X on them, the Y-X did not change to yellow as it was to start working loosing up the old sealer from the lights and I thought that was strange, the last time that happened was when someone used a spray lacquer to seal them and I knew they were sprayed on that set. I did not see any sign of that on this one. So after I started to try to sand the lights down It was hard are He## to try to remove the sealer, I tryed wet sanding and dry sanding with my orbit sander and wet sand by hand... I even was down to 230 grit. I used 10 discs to try to remove what was on the lights. Not much luck, I then thought I would just go over the top of that sealer by using Dvelup compound, Y-X and coat the lights as is. They did not look bad as I was using water when I was cleaning up the sanding residue ( No repeling), as I wiped on the sealer you can see that is was repeling the sealer and acting like a silicone coating was on them even under what sealer I could remove. I removed the sealer and then wiped them down 3 times with alcohol after it would dry each time, then I tryed to reseal the lights again... Same thing. After 3 hr.s I had to throw in the towel till I can finger out what is going on.

I called Dvelup and Mini and Ben Could not figure our what I could do at this point.. Ben did say that there has been some people starting to use a silicone based sealer.

I also Called GT and they had no help either.

If the dealership does remove the lights, I am getting them. They are already spoken for to use as a Ginnie pig for what is being done by hackers.

Have any of you guys ever ran across this and what did or could one do?

Regardless of what they put on them it should have sanded off
I tend to believe they are a case the plastic is fogged all the way through I have seen a couple ford trucks this way the plastic itself had changed not just damage on the surface unsure why but both were 10 yr old f150,s?

Can you tell me what the year/make & model of the vehicle..

It was a 2000 or so chev. Impala.

I won the battle on this one after coming back a couple days later. I got the GT Polyhog Jepson polisher / buffer out with dry 220 grit. I used 10 220 grit discs, then the matebo with wet 400, 1000, 2000, Dvelup compound, and sealer.

Not kidding it took 2.5 hrs. 2 of it was just on the 10 discs of 220 grit... You can see heavy flacks of sealer on the ground. What ever was on the lens was about as thick as a sheet pf paper... It may have been sprayed on clear coat. But it was smelling like burned plastic as I was grinding away...

The dealer was verry glad I took the time to come back to give it another shot. I think the car is sold now.
I am just glad I was able to save face on that job.
