Hi All,
 
I have a 1974 Hustler 21 foot tri-hull. I am in the process of restoring this gel coated fiberglass boat.   My issue is that the gelcoat is gone on much of the boat so now the metal flake is exposed.  How do i deal with this?  Is there a product that can cover/prime over this without having to sand all the way down?
 
Thanks...Dave

Dave,
 
If you could answer some questions so we can better assess your situation:
 
How long is the boat going to be submerged in water?
Will you be painting both above and below the water line?
If below, are you looking for an antifouling paint?
If above, would you rather work with two part or one part products?
Are you looking for a clear gel coat finish or an actual paint?
 
We look forward to your response.
 
Thanks,
Joe

Hi Joe,
 
Thanks.  I am up on the Fox River in Northern Illinois and the boat is in the water 4 months of the year.  It IS NOT on a lift so wet all the time.  I will be painting above and below the water line.  I am not sure what antifouling paint is and if it makes sense to use it.  I would assume since this boat has not ever been on a lift that the hull has already been comprimised?  It doesn'k leak or anything but that fact its been in the water all this time is paint going to "stick" and not blister?  This is a 35 yr old boat that I am just trying to make presentable without spending a ton of money.  I am not sure whether I would use 1 or 2 part paints.  I am looking for recommendations.  This is a fiberglass, metalflake and gel coated boat.  The gel coat is VERY worn and in many places completely gone. 
 
Thanks again...Dave

Dave,

Thanks for the response.
 
Antifouling paint is a coating used on the bottom of boats to eliminate the growth of fouling such as hard growth (barnacles, shells) or soft growth (slime, algae). When the boat is submerged in water for a longer period of time, this kind of growth or fouling will stick to the bottom, causing the boat to lose performance, fuel economy, and could cause vibration when running.
 
Now with your project... For above the water line (not to be submerged) i would recommend using our primer Prekote (1-2 coats) and our topside finish Brightside (2-3 coats) to achieve a durable high gloss finish with excellent UV protection for seasons to come. If you have any serious imperfection i would recommend filling and fairing before the primer with our Watertite filling and fairing compound.
 
Below the water line you will have some options. If you are looking for blister protection, i would recommend our Interprotect 2000E (4-5 coats) for the ultimate blister prevention system. From here you can go with either an antifouling paint or if you are not interested in an antifouling paint, i would recommend VC Performance Epoxy. VC Performance Epoxy is a durable two part epoxy finish that will only come in white however will have a slight semi gloss finish (similar to a gel coat finish).
 
If you are looking for an antifouling paint, a multiseason antifouling paint will be the best for your shorter season. I would recommend using Micron Extra (2-3 coats) for multiseason protection against both hard and soft fouling.
 
Hope this helps with some recommendations for your project.
 
Thanks,
Joe
