I have been removing the silicon snake from my belly band. Could not get the DAP product but tried out Mckanica Silicone Caulk Remover Gel and Motsenbocker Lift Off.
It was 57 - 60 degrees fahrenheit for most of my work. Prior to using the softeners I used a plastic putty knife to remove "the rope" and as much loose caulk as possible.
The McKanica was $10 at Ace hardware for a 3 oz. tube with an applicator tip. Motsenbocker was $5 at HomeDepot (darn near everyone carried it) for 4.5 oz and came in a bottle with flip up nozzle like house hold oil.
I had to cut the McKanica tip back to the 3rd joint to even squeeze it out, the stuff is very stiff. It came out like little rabbit turds that fell off the tip. I found I could spread it with my finger wearing a disposable plastic glove. Left it on for a little over the 3 hrs recommended. Wiped with paper towels. Then scraped with the plastic putty knife wiping glop off on a paper towel. Got down in the grove with a small stiff auto detail brush. I think it would take two tubes to do my 13 ft scamp
McKnanica worked ok. There are a few spots that required more work to get the remaining caulk but after 3 hrs it was pretty easy to remove most of it. Note it did raise a tarnish like film on the alum. belly band but that wiped off easily with a paper towel and a rinse rag.
The Motsenbocker I dribbled on, it was pretty thick a little thicker than wood or elmers glue. Spread gently with a tooth brush. Left it on for a 5 minutes and scraped with plastic putty knife. It thickened somewhat as it sat. Found going at the caulk with a stiff auto detail brush before scraping helped. You might get away with a single bottle but plan on two.
Motesenbocker worked ok. But tended to require repeated applications to remove the thicker caulk residue. Leaving on for a couple of extra minutes seemed to help. It did not so much dissolve the caulk as break down it's bond, 1/4 inch band treated then scraped off left an 1/8 inch band which after another application scraped off.
I would say the McKanica is better at bulk removal but I found the Motesenbocker better for getting rid of the small residue spots since it does not require a multi hour wait. Only a gloved finger worked well for spreading the McKanica so plan on having those.
Note both of these products would probably damage your decals so plan on masking those off with some protective news paper and watch for drips. McKanica being so thick it really won't drip when you apply but at removal while it is still thick it could drop a glop on your pin stripes or logo.
