For anyone that hasn't heard of it, GacoRoof is - by far - the best roof sealer.

 

Developed in Seattle, it's 100% silicon!

 

This comes highly recommended by many RV'ers.

 

I used it on the roof seams of my 33 yr old Winnebago and it works great!

 

Be warned - it's NOT cheap - can run between $60-80 for a gallon can but worth every penny.....

I used the elasotomeric white coating on mine. Cleaned and scrubbed the top with detergent and degreaser and then when dry applied a good thick coating with a brush and roller-after drying for a day or two added a second coat. This is tough stuff.I don't have much faith in silicone. I have yet to have even the slightest leak. BTW I got my sealer from Tractor supply.

so what was the price of this at tractor supply?

If I remember it was around $70 for a 5 gallon pail.

ty,i live 4 miles from tractor supply,found lots of leaks this week after all our rain,will wait for her to dry out!

No matter what product you use be sure to check the expiration date on the product before you buy.  Some manufacters have use by date on the container, others may have a date code, you must call to check.  Don't let anyone tell you that expiration dates don't matter!

Before you pay for what ever product you choose, check the expiration on each container.  Some manufacturers provide a "use by date", other manufacturers use "date code", if it is a date code call the manufacturer for the use by date.  Don't let a store employee tell its still good or that an expiration date does not matter.

ty for this info,i will look for expiration,i would not have known it would even have one on a product of this kind...

One other thing when prepping the roof I initially used hot soapy water with bleach in it to kill of  fungus and such.Then rinsed it with plenty of water then went back with a degreaser in water.  A good quality stiff bristle brush works wonders. Before I applied the roof coating I painted all the seams and cracks with the stuff and let it dry before rolling the rest of the roof out. Applied the first coat let it dry for a day or so then applied a second coat..has held up great no leaks what so ever.

Nice and thorough. Folks would do well to listen to your "prep" instructions. Save a lot of work later on. 

does this sealer come in alluminum color?

Current price is 89.95 at Tractor Supply here in the southwest.This is for 5 gallons. I am wondering if I should use eternabond on all the seams and around the vents first though??I have used something like this before,but didn't allow dry time between coats,and only applied 1 and half coats..Now is flaking, and some leaks around vents..??thanks ..ben

Nick what was the name of the elastomeric  coating you used and did the directions tell you to use anything special before  applying the coating ?

I need to reseal my roof , the dior says you must use an activator/cleaner before putting the coating on .

Thanks
