Duplicolor Dupli-Color, Multi-Purpose Self-Etching Primer, Green, 12-Oz

I sanded my aluminum boat with a grinder down to fresh aluminum not having to do much work as far as using this duplicolor after i sanded i noticed the swirls in the aluminum from the grinder but i used a bit rougher sanding pad to work faster after i sanded just use meguair car wash rubbed it down then rinsed dried then sprayed brake part cleaner to let that evaporate up then sprayed the duplicolor self etch primer and man she look professionally done it even took out the swirls from the grinder and laid flat no gloss strong or foul smell but this was for a aluminum flat application so i will be looking to stock up on it to i think it has a good spray nozzle to great product for prepping metal to paint

I used the self-etching primer to refinish an outside door mirror for my muscle car. The mirror was chromed but old and pitted. I wanted to paint it to match the car's body color. I sanded first using 80 grit paper then with 180. That removed/smoothed the chrome enough to use the primer. Following can direction, I sprayed 3 light coats I waited 5 minutes between coat. Letting mirror dry for 8 hours the finish was fantastic. Pits and sanding scratches gone. Time to apply the top coat.

Used product on a rusty 20 yr old truck. After sanding down to bare metal, product covered and smoothed out most of the scratches and imperfections. Was found easy to use by a first time painter of a vehicle.

I used this as a primer on exterior aluminim trim that had faded badly. This primer ran easilly but was easy to sand out. I then sprayed with a good quality exterior spray on paint. Turned out great.

Great Product, works as described
