Can I scuff the surface and spray with exterior latex enamel? We do this all the time with PVC and it works fine. Manufacturer recommends metal bonding primer and then top coat - but is there an easier way to go? Thanks.

I would not use ordinary latex without some good testing. There are some specialty latex paints for unprimed (bare) aluminum but I dont really care for them, they seem pretty easy to damage. I have scuffed and used 1 shot with the hardener with good success. But the best way I have found is using a urathene paint on a scuffed surface, it makes for a great finish that will last for a long long time.

I prefer a water-based product over a solvent based product. I have become sensitive to the fumes lately (guess it's from ingesting lead paint for 20 years). Also the citrus-based adhesive removers are starting to bother me. Yes, I have a respirator mask, but it doesn't get used all the time.

best thing for aluminiun and galvanised steel is powdercoat cheaper than paint to and lasts longer

I have painted a lot of di-bond. The best is to just scuff and paint with automotive paints; second best, scuff and roll on buletin enamels: Believe it or not, you can just paint on latex, and it will weather for years and years. It is very odd though, you can easily scratch it, even with a finger nail. If it is out of traffic, the scatching is no problem. I have a job put up 17 years ago that the background is still good on!

I paint dibond all the time - but I buy it ready powder coated which gives me a good surface to paint on. I usually scuff it with a Scotch Pad and paint with automotive paint - respirator is compulsory.
If you have plain aluminium to paint on then you will need a self etch primer. It often is a 2 part paint. One part bing the activator. But it is expensive and time consuming. Far better to buy the ready powder coated dibond and the paint it whatever colour the sign demands. I don't recommend Latex (emulsion paint)for the job.

Would definatly use the acrylic urethane/ automotive route- yeild a long wearing finish. I'm in your area and can do this work if health issue is a problem.

See if you can locate Krylon Latex paint for metal... it's amazing the finish this paint gives you, it comes in different types of finishes as well..ie. flat, semi flat, semi gloss. high gloss. It works grat on wood as well, dries in about half an hour. We use it all the time. It looks alot like 1shot, try a sponge roller as well. Neil
