I’m planning on getting a better cauk gun for use on my RV. I’m not so much interested on what name-brand gun to get but rather what thrust ratio would be best .. 12:1 .. 18:1 .. some other number. Since I have never worked with the type of sealants used on RV’s I would be interested in any recommendations.

Thanks

The standard sealants are thin as compared to say roofing and asphalt sealant that you almost need to heat in cold weather. Not much different in weight then say standard window or bathtub sealant.

Don't go too crazy with a high ratio gun unless you have hand problems with limited squeeze strength. The harder you push the fast the stuff comes out and "the bigger the glob the better the job" technique isn't always best. I think mine is a 12:1 and takes a very light touch to get the flow volume needed to match my movement speed.

I also have a 18 volt Ryobi battery caulk gun.
Works great, saves a lot of pain with the arthritic hands.

As a contractor my whole life and having tried every option I always ended up with the old school ratcheting style guns with the chrome Newborns being my go to. I believe they are 10:1 and do require a bit of pressure, but seem to give the best results with the least dripping.

When caulking an area that shows, I mask the outer edge of the caulk line prior to caulking with masking tape. Then remove the tape after caulking. This method gives a straight edge and a very professional look.

Also being in construction most of my life, and doing tons of trim work and finish work, I've used these for close to 20 years:

The one I've got now is probably about 10 years old and still works like a champ!

They are under $10 bucks, and take up very little room. Dripless, meaning once you quit squeezing the trigger they stop flowing the caulk.

At the price, even if they only last a couple of years, which they will last a heck of a lot longer, how can a person go wrong?
