See full version: How to Paint Fiberglass
Painting fiberglass is tricky because the surface is smooth. With the right preparatory steps, however, you can get a smooth, professional-looking finish. The trick is to take your time and go slowly, especially between layers of primer, paint, and topcoat (if you are using it). The exact paints you use will depend on the object you are painting and its intended purpose, be it a boat, bathtub, chair, or door. [links]

To paint fiberglass, first clean the surface thoroughly with soapy water and let it dry. Then, sand the fiberglass with medium-grit sandpaper to remove the slick finish. Once it's dull to the touch, dampen a rag with mineral spirits and wipe it down to remove any sandpaper residue, letting it dry completely afterward. Next, prime the fiberglass with an oil-based bonding primer, using a brush to cut corners, edges, and uneven surfaces. For flat surfaces, use a foam roller. Wait at least 24 hours for the primer to dry, then use the same technique to apply a coat of acrylic latex paint. Wait 24 hours for the paint to dry and then apply a second coat. Finally, once the second coat is dry, spray on a clear exterior topcoat to protect the paint and prevent chipping. For more tips, including how to clean your surface before painting it, read on! here
Re: What primer for rustoleum paint on fiberglass hull?
I painted a 15ft Tri-Hull both above and below the waterline with Oil Based Rustoleum Enamel and ran up and down the lake for 2 seasons and even ran it up on sand a few times. No problems at all and I spent about $50.00 total on materials. In freshwater you don't have to worry about the stuff that gets on a saltwater boat. Proper care should be taken but like I said. I did it.. I used it and it came out great. [links]

The coating of this product prevents premature wear-through. However, a slow polishing action minimizes needless paint build up. Furthermore, the surface continually smoothes with use, offering a quick, fuel-efficient coating. here
"Basically, a refinisher turns a residential bathroom into a spray booth for a few hours," explains Mike Grampp, who runs a thriving 11-year-old tub refinishing business in Richmond, Kentucky.
If you're considering a tub liner, determine whether the company has your exact tub model before you sign a contract. Call the headquarters where molds are made if you don't get a convincing answer. [links]
The whole process takes a single technician about four to six hours, depending on how extensive the repair is, but the tub needs to cure for a minimum of 24 hours before the water is turned on.
Both industries shy away from working on fiberglass tubs, and most liner companies won't do jetted tubs, nor will they line claw-foot tubs. Chipped, dented or even rusted-through tubs are no problem, however, but be prepared to pay more if repairs are necessary. here
Also avoid companies that use PVC liners. They are less expensive, but they tend to yellow with age, and they are thinner than acrylic. Because there's no regulation or certification of this industry, ask for product-safety data sheets on adhesives and any other chemicals that will be used. [links]
Re-Bath, a Mesa, Arizona-based company, has been making tub liners since the 1970s and today is the nation's largest franchiser of tub-lining products, with almost 100 installers in 47 states.
