Fusion adheres better to the PVC than other aerosols and many have had good luck with adhesion and it causing no issues. Just make sure that any that will be in tank is plenty cured.
Not really when you consider you can get it locally and do it yourself easily for cheaper even before your order would have been received from BRS. I considered it but when I added up the total cost and the fact that if I needed more or less I could easily get from Lowe's if I needed to go back. Otherwise I'd just have to order more than I would need from BRS just to make sure I had enough and then be bothered with selling it or returning any left over. That said Synergy is local and they have red and black pipes as well.
I work at lowes so I got a great price on all my pvc just thought I would try and paint it so it wasn't so bland. Should I paint it after it's been glued? it won't restrict any ball valves or anything will it?
Personally I like the two toned look where the valves are a different color as the pipe, @iiluisii just redid his and it looks great. I've never painted it but I would think that painting it after glued and leak tested.
