Acrylic paint films have properties completely unlike any other medium, and these properties have to be respected in order to produce a quality product. They also vary considerably between manufacturers; the actual polymers may not be "acrylics" per se, but polyurethanes, vinyl acetates, and/or acrylic/styrene co-polymers either singly or in mixtures with actual acrylic polymers. The chemistry and film properties vary accordingly, so one brand may not react the same as another.

The end product can be nasty stains that are impossible to remove. I also noted that without a final sealer, the acrylic film remains somewhat "tacky" and any surface dust or dirt can…Continue

Some shapes, like boat hulls, can be a real pain trying to figure out the perspective. I found a quick way to produce a line "drawing" from a photo using Photoshop. My software is nearly 10 years old, and apparently this works many versions, so you do not need the latest and greatest.
Just remember to save the line image with a new or modified file name so you do not…Continue
