Any tricks for mixing Proseal?

[Cadstat]

Are there any tricks for mixing Proseal? I bought a scale to do the 1 to 10 by weigth. Also do you mix it in a wax cup? I hear it sticks to everything.

Don't use anything that is waxed mixing Pro-Seal or epoxy. It mixes a lot easier when it is warm. I keep my epoxy and Pro-Seal in a temperature controlled hotbox set to 90*. You can buy some nice 16 oz clear plastic food grade containers from Gordon's foods or other restaurant supply store.

I used the smallest available paint mixing cup from my local auto parts store to mix Proseal in. Weighed it on my postal scale, mixed with tongue depressor or popsicle stick and loaded it into a veterinary syringe. Mixed and used indoors in around 70 deg F air temp.

On the advice of others (Mr. Dooley), I'm mixing on a ceramic tile. I'm using a putty knife for mixing. I was somewhat disgusted when I went to buy a new putty knife and it was some funky shape, rather than the square cut knives of the old days. I bought one anyway and found the funky shape allowed for better mixing. Who'd of ever thunk it! I've found if I keep the hardner off the tile, I get a good clean mix and don't have to worry about any unmixed hardner making its way to the semco gun. Let the goop dry on the tile and remove with a single edge razor blade and you're ready to go again.

Thanks for the pointers. The Pro-Seal is sitting in a little can on the shelf and will be put to use before too long.

- I always just weighed and mixed the stuff on little disposable plates. I got it out of the containers and mixed it with craft sticks.

- Don't be stingy with the latex gloves. Change gloves frequently and you will minimize mess.

- Sometimes it is useful to put the proseal into a sandwich baggy with the corner cut off to help apply a line to the target.

My wife has an inexpensive electronic postage scale that I use to weight it out. I zero the scale with the paper plate on it (what ever I use to mix it in) to minimize the math. Very helpful.

I just finished my tanks yesterday! Edit: waiting a few days then doing the leak test. That will tell me if I'm really done?

My advise with Proseal:

Buy the pack of 100 count gloves!

I started the first tank with a 10 pack. Proseal migrates from surface to surface. I underestimated just how messy it is (even after reading all the threads). The 10 pack lasted about 15 minutes and then things like finger tips, tools, parts became gummed up that much quicker.

The next round I started with the 100 pack. Almost every movement I changed gloves and tossed them in the garbage. Mixing and then toss, line-up part and toss, install rivet and toss...etc.

Once I started doing that, everything was MUCH easier and cleaner to deal with. Compared to the mess during the 1st round, the rapid glove change proseal was actually enjoyable... relatively speaking

gloves were too much of a hassle for me, just MEK your hands clean, unless you do this daily/professionally, you won't die from building a set of tanks

For proseal, here's what I ended up liking best (or hating least):

-flexible plastic bowls about 8oz size from restaurant supply store. You can easily peel the proseal out and reuse after it has dried.
-An aluminum stir stick about the size of a tongue depressor made from scrap aluminum. Much easier for thorough mixing. I kept breaking the popsicle sticks. I used the popsicle sticks for measuring out the two parts and then threw them away.
-A good scale with .1gram ability and tare feature. Probably overkill but I really liked being able to accurately measure small quantities. I always knew the ratio was close to exact.
-Lots of 2x2 squares cut from old t-shirts next to a small bowl of MEK.
-Box or two of latex gloves.
-Semco sealant gun. Felt like cheating!
