The EGR variety in particular. The foam seemed not of the highest quality, seems like maybe 2 years max before it start drying up and deteriorating. I've got the white foam painted black with acrylic paint and a tiny brush, why in the world could they not dye the tape black in the first place? Every truck on the road has the white sticking out all over. The horror. Would hate for it to start to separate.

 

Are you talking about the window visor/vent visor things? I've got the stick on type from GT Styling. Had them on for about 4 years now, still holding fine.

 

I have EGR vent visors and a bug deflector. They are mounted for tree years now, no problem.

 

My vent visors™ have been on for 4 years now.

 

i have the Gt Styling ones on about 3 years now and absolutely no probs!
