I have had very good luck with Southern Polyurethane's products. Excellent customer service, good pricing, quality product. I've used everything but there basecoats and they have all worked very well for me
X2! Their epoxy is fantastic and I spray NOTHING but their clears. For an overall show car type job I use the Universal Clear. Goes on like glass and buffs like a dream. Follow their "show car finish" directions and you'll be very happy. Barry is an amazing guy, as well as all of his staff.
