Talking Blow in insulation over wiring?

I just put a layer of R-13 in my attic, as that was the only one that would fit due to all the wiring running from end to end. I want to blow in additional insulation but not sure if it is ok to put it over the wiring. Thinking about bringing it up to at least R-30. Is it Ok to blow it in over the wiring, and if so is it best to use the pink fiberglass blow in, or the grey Ecco type of blow in? I put the pink faced R-13 down. Any help would be greatly appreciated. Thanks!

i cannot tell you for sure but i can tell you i did it using green fiber to bring everything up to r60ish over the existing pink stuff. i do know it's important to watch out for can lights and properly baffle them. I also think it's a good idea to take pics 'before' and print them out so you have them for reference to know where they are. i also built a walkway with 2ft x 4ft plywood so i could walk along it even after everything was covered if i ever needed to.

i do have another thread on here with questions i asked the guys and i think they were ok with the fiber being blown over everything. but it's best to confirm that and maybe even read the manufacturers instructions. I think the how to sections at the top of this board are helpful too

The only wiring you don't want it to touch is knob and tube, otherwise it's fine. Do take care of any can lights as luckydriver suggests.
