I need to replace a small area of rotted wood on my RV. I'm looking to cut and lift a portion of the existing rubber roof to do the repair and will then re-lay the existing roof back down. I will use butyl tape to cover the seams and then use the Liquid Roof to coat the entire roof. I do not want the roof to look like it had a repair job. Will the Liquid Roof be thick enough to where the butyl tape will not be noticeable?
