Once the finish is completely stripped down to bare metal you need ro rough up the surface with some 600 or 800 grit sand paper to ensure proper adhesion of the Bulldog. During this process pay careful attention to areas with any corosion making sure that all is removed.
Next you need to make sure the surface of the arms are completely free of any surface contaminates (dust, grease, grit and any residue left by the Aircraft stripper) by first washing with a light soap and water mix. Rinse the amrs and let dry completely. Once the arms are dry, dampen a clean rag with acetone and thoroughly clean each arm. Acetone, if it is completely pure, will not leave any residue creating a contaminate free surface.
The next step is to lay down a good base for the paint to stick to. Since the surface which you are covering is aluminum an adhesion promoter needs to be used to ensure that the surface will hold the paint. I used Bulldog adhesion promoter in 3 light coats (it runs very easily) on the arms..
It dries very quickly so within 3-5 minuits after the 3rd coat I was able to lay the first coat of the Duplicolor bumper coating. Much like the Bulldog, the bumper coating runs very easily and needs to be applied in very light coats. I applied 3 coats of this as well, allowing 3-5 minuits between coats to ensure it would not run. This is what they looked like after the first coat.
Once the final coat of the Duplicolor is on let dry for a few hours before beginning to install them. In my case, the humidity and temp of my garage was not optimal so i needed to use a hairdryer on a low setting to speed up the drying process. Here is one almost dried.
