combating the fog

its about time to get back at it. first order of business is blasting. like most of us over 40, i have to wear reading glasses. admittedly i have a cheap blasting hood, but any of you have any pointers on keeping both my glasses and the plexi in the hood from fogging up?
its pretty aggravating, both are fogged up in minutes.

I use this hood from Tractor Supply. Cheap but works good.
It has a hard hat inside that holds the face plate away.
No fogging of my glasses when using.

 
Wiping the inside of the face mask lens with "Barbasol" shaving cream will provide a protective coating that resists fogging. It'll also works on eye glasses. Coat the outside of the eye lenses.

really? wow i didnt know that. thanks. i was wondering if rainx would work or destroy the plastic.
 
After fighting the fog for years I switched to a 3M visor and a Tyvek suit with a hood. Replacement lenses are relatively cheap.
Don your not wearing a hood then? i assume you wear a respirator then? i get the media inside my clothes even with the hood. i do have some tyvek suits here..........its pretty hot and humid here though. if i get the temps to paint im sweating in the suit.

Yes I wear a dust mask. No hood. Just underwear and a tee shirt under the suit. I blast early in the morning at the crack of Don, er I mean dawn… :D

You don't get eaten up by the blast media? What are you using for eye protection? My hood I have to change the lens often because the media etches it so much.

I wear the 3M full face visor that I posted above and replace the lens as needed. It doesn’t fog up like the blast hood. Not as hot either.

I run 2 strips of 1.5" masking tape across my 4.5" lens. 1 in the center, then 1 across the top. I then look out the bottom until it gets hard to see, then remove a strip of tape and look out that section, then do it one more time with the last tape. I get 3 times the use out of each lens that way.

The Tractor Supply unit I posted has a metal screen over the lens, kinda like window screen material. Doesn't obscure vision at all and keeps the media from etching the lens.
Just pull the lens and screen out occasionally to clean. Pretty slick.
 
I media blasted this part today wearing shorts, short sleeve shirt, ball cap, dust mask and safety
glasses.......can't forget about safety.

Fabricated a bracket for my bead roller. This bracket was made from spare metal in the garage, consisting of two pieces of 1/8" tig welded together for the base. Then 1-1/4" x 1/8" angle notched. Media blasted and ready for epoxy primer.

I use a really lightweight cheap hood with the lens removed. The fabric is just some really cheap muslin about as thick as a bed sheet. And top that off with an old welding helmet with the dark lens removed. I sawed up a sheet of polycarbonate for replacement lenses. Because the helmet is all open in the back it never fogs.
 
cant comment on the fogging because mine hood does fog up but for the lens, i had a couple cut from tempered safety glass. last about as long as 15-20 polycarb ones so your not changing them all the time. way better.
 
years ago, when we had chicken houses, i had a helmet with a full face shield and a belt battery. that thing had a fan and filter set in the back that blew cool filtered air over your head. i didnt use it much back then but wish i had it now. i checked, they cost 1k now days!
 
i use a bullard hood and run my air through a chiller. chiller is a blue plastic barrel has a copper coil in it. fill with 55 degree well water and dump some frozen milk jugs in it. keeps you cool and 0 fog.
