Reflective Material Vs White Paint?

Hello everyone
So, the past few months i have been pondering about and gathering materials for doing my own grow and such, and finally i got all the things i need except for a few minor things.. which are either in the mail or a 10 minute drive away..


Anyways, i start throwin up this reflective stuff all over my cab and im really close to being done, and then a fellow friend tells me white paint is a much better option.. and more reflective.. which is annoying cause that was really tedious putting that crap up.

so i tryed searching on here.. i couldent find exactly what i wanted to know.. and then i found out ripples in the reflective material can suck if its not flat.. and thats no good cause its not the flattest, its got ripples all over.. its not horrible but enough that im concerned.

i have already spend enough money on this so far, i just want to make sure i get the best for my babies im willing to rip down the emergency blankets and paint it if it is a better option.

i would really appreciate any feedback!

I prefer paint, but reflectives are much better.

if its an emergency blanket you are most likely going to be fine, just take the time into making it as straight as u can...tinfoil is what u want to stay away from because that will cause hot spots.

Stick with the blanket stuff man just flat it out, painting could get messy for some people, its not as reflective as the mylar , and u already put it up !



Cheers

I use Reflectix insulation. not cheap but readily available and reusable, to an extent.

mylar bounces back 90%+ of light. no way in hell the whitest walls can do that...
