Review: CRAZY GLUE OF ACID ETCH PAINT - Let me tell you. This stuff is amazing. I have a project jon boat. I have used other products in the past that didnt cover well, stick after meticulous prep work or didnt last. This stuff is crazy glue of paint for bare aluminum and old galvinized metal trailer. Used an automotive spray gun to apply 2 coats. First coat covered everything. Dried to touch in about 15 mins. Applied a second coat at about and hour. Lays flat, and smooth. I highly recommend not using any other product. THIS STUFF IS THE BEST HANDS DOWN.
Review: It stuck - I'm not big on premixed but,it did work and layed smooth, price was reasonable
