Disambiguating the buffing ambiguities

One of the problems is I have a torpedo heater running in the booth so it's too loud to hear those, and if the air compressor kicks on outside it's even louder. Sometimes you can actually feel it because I've not pressing very hard on the block/paper. I use copious amounts of sudsy water too. It should be warming up here within the next month where I don't have to use it anymore.
 
i have a 1/4 in line with a bug spry nozzle on it. i keep the area flushed and clean. bucket sanding just leaves you hanging. one piece of grit and you have several nice 100 grit gouges to try and deal with . sanding again will likely result in another set. i have to change the filter on my hose pretty regular . all kinds of crap comes out of a hose.
when it comes to those big swirls i just polish it out. no point in putting more scratches in it .
 
For my source of water I use a spray bottle or a giant sponge saturated with water that I let drip over the area I'm sanding. Right now on our place the only source of unfrozen water is in the house so I can't run any hoses. Hoses aren't so compatible in wintertime Michigan. I've still got a foot of snow in my yard even though we've been a week into the thaw. I clean my bucket out daily and start with new water every session. The sponge works nice for horizontal panels but the spray bottle is better for the vertical parts.

The sponge I use is microfiber on one side of it, so it works real nice to wipe the panel down with that after I'm sanding to remove everything, kind of like a soft squeegee.
 
I think you should lose the sponge and use clean paper towels to dry your panel. The squirt bottle should be fine if the water going in is particulate free, but sponges and buckets are dirt magnets.
 
i wet sand my epoxy but try hard to just dry sand the final clear. everytime i grab the sprayer i hear jim in the background saying " dont do it " . it's just hard for my old brain to accept dry sanding. old habits are hard to break .

thanks jim :encouragement:

Shine, I assume when you are dry sanding the clear it has to be cured pretty well for the paper to cut?

How is the seat arrangement different? There both rotary right? I am digging the light weight though!

And careful where you set the squirt bottle down, everything needs to stay clean

I bought one of these spray bottle holsters so I don't have to bend over or worry about dirt on the bottom of the bottle. It's used by dairy farmers to spray udders clean. At around $4 it seemed like a good deal.

well I'm glad it's not just me who's overly anal, because I never let my squirt bottle sit on the ground either. I hang it on the edge of the bucket. I'm a scientist by profession, and in the lab I work with bacteria or cell culture and do sterile work, and I mean STERILE work, where something as simple as merely removing a cap from a tube or removing a pipette from a wrapper requires good and proper technique. It's a mindset and skillset that becomes second nature, and I must say the level of anality conveniently translates to this type of work too. I also put on a clean t-shirt when I go to cut or buff and make sure I don't pet the cats or dog; I don't want hair falling onto the surface of the metal and making a nice scratch when it gets caught under a piece of sandpaper.

At any rate, it's been a while since doing this work, but here's how it came out...IMG_0757.jpg
