Pro Seal:Old dog learns new trick

[Vern]

As a veteran of many quart cans of ProSeal, multiple rubber gloves, and tongue depressors with the resulting mess, I was pleasantly surprised in my first use of my hand-operated dispensing gun and a Proseal cartridge. Wow! I could have used it with no gloves on and in my best suit! A very neat application method.

The only way to go!. I just use the cartridge (don't have the gun) but between that, and a nifty little mixing attachment for my cordless drill that I made, it's WAY better than the quart method...

Semco guns are the only way to go with Proseal. I got mine for $26 on ebay but would definately pay full price if I needed to do it again.

Timing on this is excellent as I am only days away from sealing my first tank. What is the technique with the gun, do you mix the proseal and load it in a cartridge, then squirt it out? Or do they sell preloaded cartridges?

[Lionclaw]

It certainly makes applying look easy, but how hard is it to clean afterwards?

[Rick S.]

I used this tool and cleanup is a breeze, remove the cartridge and toss in the hazardous waste disposal can. I recommend the old fashioned method for assembly e.g. tongue depressors to apply the muck to the ribs and this tool to do your sealing inside the tank or anywhere you can take advantage of using a full tube. You can buy empty tubes and fill them if you want to use that method (not fun or very easy). Using the tubes is a lot more costly. The Semco gun has great control for laying out a bead. Remember that once your all mixed up you have to use or loose the remainder of the batch. Get the mixing tool if your going this way...saves a ton of arm work.

Is there a difference between the semco gun and just buying the tubes and a penumatic calk gun?? I can't find a semco gun cheap!! Anyone in Dallas have one I can borrow when the time comes?

[Slingshot]

Yep, those tubes of Pro Seal are expensive and there is a lot of waste. I'm sure the Semco guns do a wonderful job but why spend the bucks? Drop by your local hearing aid shop and for a couple bucks buy a few of the syringes they use to make ear molds. When ready, mix up what you need from your quart can of Pro Seal, load the syringe with a fat popcicle stick and apply. You will find the syringe is even easier to use than the gun because it is shorter and easier to get inside the fuel tank. When done, clean it or toss it. No big deal. Enjoy.

I bought the cans and mixed the size of batch for the job, and stuffed it into the tube. There is a plastic plunger that follows the sealant into the tube, put the tube into the can, secure the can lid and start laying beads.

Order several tubes and nozzles. When you are done with a mix, blow out the extra into the trash, if any, then push out the plunger. UNscrew the nozzle. Set the plunger, tube, nozzle aside. In a couple of days you can remove the proseal from all the plastic part by flexing them to break it loose. They can then be reused.

Or you can buy the ready to mix cartidges, but as said before, can creat a lot of waste.

When putting a dab on the shop head, move the nozzle in a swirling motion, encircling the head on all sides.

Just finished up the pro-seal work today with the completion of the last tank. One thing I found different than posted, is cleaning your hands. Yes I know, we are supposed to use gloves but that's not me. I found that the Fast Orange hand cleaner washed the sealant right off, no problem. Sounds like I'm running a commercial for the product,ha!
