My 5ver is new, will I need to use a primer to put eternabond on my seams and around my vents?

If the roof is clean and the sealant is fresh, most likely no. However the EB is EXPENSIVE and I would hate to have it redone because it did not stick somewhere. Additionally it is hard to get up (not impossible; but a PITA) if a portion does not stick well. It is also very easy to cut the roof membrane trying to trim up a bubble or crease that did not stick.

IMO the primer is cheap insurance; use it.

Use the primer as Lou says............I learned the hard way! Brandy new camper....had a couple of spots that didn't stick well. Better safe than sorry !!

I read that Walmart supply it, do they supply the primer also?

You can also use acetone as a primer as per manufacturer instructions. They sell a primer (likely acetone based) and it may be more convenient and maybe have some additional cleaners or something. I used acetone and it seemed to do a good job. Acetone is rough on the hands (extreme drying agent) so you'll need to wear gloves.

I am sure the primer is spray acetone. The spray is worth the convenience and no worry of splashing it in your eyes or spilling it on the roof (bad!).
Just make sure you don't look into the little hole when you hit spray!

If you use acetone instead of the primer, do buy 100% acetone, not nail polish remover. There is a lot of other stuff that might nor be good in the dime store stuff. A place like Sally's has the good stuff.

Acetone is also available by the quart at Lowes and Home Depot in the paint department. DON'T spill it on the roof!

Anyone have issues with the tape sticking even when using acetone? Mine came off.
Perhaps I got a bad roll of tape?

I just received my rolls and tools. I missed getting the primer, but did get Acetone from Home Depot. I am going to do it during the summer when we are at our campground and while the kids are playing. I figured its going to take me a few hours. Should be fun in the Florida Sun in June:cool:

According to this thread, Acetone should be OK. I always worry about wind when I use sprays. I am not lucky enough to have an enclosed area to work in....
