i wouldn’t, unless you’re planning on bypassing the manifold. that thing has cheap steel or brass guts. roof mix will chew it up quick. you really need a reel with stainless guts.
I have a reel that’s the same size as this one (100’ of 3/8") and it holds 300’ of 1/4" hose fairly easily. I’m betting you could get upwards of 500’ of 5/8" hose on it.
My reel is practically a clone of the one used by RHG, minus the carry handle and rubber feet. I got it on Amazon for under $40. Not trying to disrespect the product, but you’re basically paying for a $200 handle. My reel has held up to 2+ years of abuse and has only required a little bike lube every once in awhile.
