Been very satisfied with the dry time and its hardness after cure. Seems to stick like crazy. I recommend Review: Spendy but for aluminum diamond plate she bonded great. - Works great on diamond plate, before I raptor lined my homemade camper trailer you can really cratch at the primer once dried and it seems to really get a good bite to the aluminum. I did run out of cans and opted to buy a can of home depots self etching auto primer and you for sure would have to rough up and clean the surface as that does not at all self etch compared to this (speaking about alm diamond plate, I did use Home Depot’s when priming my Tahoe to raptor line and that did work great in that application but for aluminum I’d go with this.) but I was on a time frame but all in all seems to be a 5 star item tad pricey but if it works and I only have to do it once.. I’m happy with that. If I were doing anything other then aluminum I’d probably go with Home Depot as it has worked on plastic wood and everything else I’ve put it on and is half price. ## Features - STRONG ADHESION: U-POL Acid Etch Primer uses a phosphoric acid ester formula to promote superior paint adhesion on tough surfaces like galvanized steel & aluminum, making it ideal for new bare metal panels & rub-throughs in primer before color application - ONE-STEP PRIMING: Etch and prime bare metal in a single step for a streamlined application process.
