i'm using the 'basic no-blush' epoxy from epoxyproducts.com<br /><br />i have gone through half my order and i have a feeling i may need a bit more. problem is, the smallest unit they sell is 1.5 gal and i'm positive i won't need that much. also , there's a lead time as it is mail order. <br /><br />so if i do indeed need more, can i just pick up a quart of MAS from one of the boat stores locally? will it bond with the epoxy i'm already using if it hasn't fully cured? obviously i'm not planning on actually mixing it together, i just want to make sure i'm not setting myself up for disaster.<br /><br />matt
