Peeling paint corrugated panels

brownbr

Here are a couple of options I have used to create peeling paint on roof panels. I included the products used for reference.

I started by spray painting the panels and then giving a coat of rust to taste. Doesn't have to look pretty at this point just get it to a point where you like it. Photo 1.

I'm using 4 different methods so I can see which I like best.

First is to stiple green paint on using a brush. Photo 2.
Second is using a base coat of chipping fluid. Photo 3. 2 different kinds used.
Third is using a fading paint additive. Photo 4.

I let the chipping fluid dry overnight then painted the panels green. Let this dry for an hour or so then begin chipping by spraying with water and scrubbing with a stiff brush. I used a cheap brush with natural bristles.

Photo 1 is using the chipping fluid only. Panel on left using "Weathering effect" and right is "Heavy chipping".
Photo 2 used chipping fluid and washable agent.
Photo 3 used washable agent only. I like this one the least so far as it did not peel the way I like.
Photo 4 I let the chipped panels dry then washed with enamel rust. Left is "Rust streaks" and right is "Track Wash".

I wiped down the panels after the enamel had dried for about 1/2 hour then brushed each with a brush dampened with mineral spirits.

Once everything had dried, this was the end result:

Photo 1: Paint over rust
Photo 2: Chipping fluid
Photo 3: Washable agent
Photo 4: chipping fluid and washable agent.

Paint over rust did just fine. My favorite used chipping fluid.

Great tutorial Bryan, thank you! Lots to review here and try. I really like the coloration on the panels. Will work great on a project I have daydreaming about!

Bryan,

Great tutorial. Thanks for sharing your step by step approach and project materials.

Thanks Brett. Can't wait to see the project.

Dave, I think there is a variety of products that could be used as substitutes if you like. For example, I think chalks could be used in place of the enamels...the goal is to tone down and blend in the paint color on the panel. I've done green and cream and like them both. Also, I took a lot more paint off of these panels than the ones on my Truck repair shop. This is a flexible technique. You can wet, scrub a little then spray it off and see if you like it. Take off more if you like...etc. In short, take off a little at a time and stop when you like it.

Kevin, I do not bake mine. I use auto primer that stick pretty well. I give a coat of primer and let it dry then look at it in bright light. If I see shiny spots I coat it again. Usually do a light shade for the top and a darker shade for the bottom. Do the bottom first.

for the corrugated shack, the instructions said to cut the panels to size, prime them with a rattle can paint, and once dry, bake in a 350 oven for i dunno, like five minutes, then flip them over and do the other side (i think...) to cook the paint into the metal i suppose.
