I'd like some advice on painting an aluminum sectional garage door. The problem: Someone painted it with latex and it is now cracking. Paint is solid but cracking. The metal has a dimpled finish. Cannot sand.
Possible Solutions: 1. Use a heavy bodied primer to bridge the cracks and top coat with latex.
2. Have door sandblasted, apply epoxy primer and use an automotive paint for a top coat.
Potential Issues: 1. Using the latex primer and top coat I fear the same problem developing because the paint will be so thick it will eventually crack.
2. The thickness of the paint will cover the dimple finish. (I plan on using an airless sprayer)
3. I desire to have a semi-gloss finish with the automotive paint.
Questions: 1. Any other solutions to use on the currect latex?
2. Do you agree it will most likely crack too?
3. Is the automotive paint as durable?
4. Will adding chems to get a semi gloss finish effect durablity and longevity?
Any other choices?
Thanks
