is that those little 3 ounce tubes? couldn't find anything that fits into a caulking gun at lowes/HD. I might have misread that shipping cost of $10 for the tube. I talked to one supplier and their minimum shipping was $10.50 so it might have covered the 3 tubes? that I want.

I have used the 3M 4000UV "Fast Cure" caulking on all my exterior surfaces and have even used one of the small tubes of the 5200. I think the permanent designation is for when you put it between two items. I think with some difficulty you should be able to get even the 5200 off as long as you are using it a a final surface sealant and NOT as an adhesive between two surfaces. If you use the 5200 or even the 4000 between two surfaces it's either permenant or extremely difficult to remove. Thus stick with buytl tape for the primary sealant where needed and then the caulking as the secondary sealant. HOWEVER, one thing to really watch is almost all the 3M Marine caulks are not UV stabilized/protected with the only one being the 3M 4000UV, both the 5200 and 4200 are not. You can get the 3M 5200 in the small tubes at some HDs. One thing is that once opened 3M recommends using the tube within a fairly short time frame like 2 or 3 days IIRC.

All the 3M caulk I have used still looks great some 7 years later so it's some quality caulking for sure.
