rolling/brushing epoxy

Hi you guys so I posted a while back I was stripping panels, and going to spray on epoxy but there was a problem with the compressor and I have to save up for a new one. But I want to roll/ brush the epoxy on the panels stripped and do it to the floor pans what the best roller to use and brushes or can I go buy any ?
 
Go to home depot and by the multi packs as cheap as you can get, as you don't want to clean but throw away.
the baby naps they have work great, the foam, I have no clue if they are solvent proof or will melt as soon as the epoxy touches them.
 
I often use the foam "brushes" to brush on a little epoxy when needed, particularly inside door cavities & other hard to spray areas. The foam doesn't disintegrate right away, but it doesn't last long.
 
get the rollers that dont leave roller material in the epoxy...doooh..ask me how i know! LOL
 
2" chip brushes, 3 dozen for $15. work great for those places that wont be seen.
 
Hey you guys, I have been busy a lot with school and work but have had time to get work done on my 68 chevelle. I got my compressor running and using the pressure pot. It's working pretty good happy with results. I just need some professional advice from the pros. I have my trunk lid and Fenders blasted last weekend. I am using black diamond, what kind of prep do I need to do after using "black diamond"? Do i still need to sand with 80 grit or can I just blow off and w&g and epoxy? The finish product is gray and has a ruff texture, not like the look of when I use stripper and 80 grit.

On another side note I seem to be running through a lot of bags really fast. I did some serching and seen a post by user "shine" about setting to 35psi and just cracking the media valve. So I'm going to try that and see if helps media last longer. Trying to play with the valve for air and media any advice helpful for a first timer. Thank you guys!

I'll let the pros answer, but I know what you mean about going through media. I have a HF 40lb sandblaster and it's a garden hose of media if I don't keep the valve close to shut. I wish I would have seen that post by shine :p I ended up getting a big roll of plastic sheeting from Home Depot and putting it under whatever I am blasting. Makes gathering up the media for reuse much easier. Now I just have to figure out a good way to clean it.
 
my blasting rig is 185 cfm /1 1/4 hose / 3/8 nozzle. it can empty my 6.5 cu ft hopper fast. you will learn that the less media you use the better it works. there is also no reason to use more than 30-35 lbs of air. the more air pressure the more chance of warping the metal. always keep the nozzle at 45 degrees or more to prevent peening the surface.
 
if you have a pressure blaster the pressure in the hopper and in the hose must be equal. otherwise you will get no media or too much media. mine is plumbed to have equal pressure in both.
 
same question as ray, probably answered in my other post in metalwork...ive been sanding sandblasted metal with 80 to get he metal a little smoother then w&g cleaner, let get warm in the sun, bring inside and epoxy...
 
Thank you guys for the answers, so then my idea was to scuff the blasted metal with 80 grit, w&g remover, then scrub with scotchbrite for any lint ect caught on the surface?

So need same pressure in pot and hose? On the compressor I turn the regulated pressure to about 50 or so (can't recall exactly) and on the gauge on my blaster it gets about 30's. How would I achieve same pressure?
