Interlux bBightside Pre-Kote

Well folks, I am ready to prime our 13' Boler. I will be using a foam roller for finish coat but should I use a low-nap mini roller or a foam roller? Would foam be better, or...?

If you look at the instructions on the Brightside paint you will see that it does you do not Pre-Kote under it when covering over fiberglass. You will only need to prime spots where you have used a filler.

So save yourself a lot of money and labor time and only prime the places you might have used filler on the surface.

As to rolling and brushing it onto the surface. The first thing you need to know is do not buy the one part version of Brightside, it works for spraying but does not work for rolling and tipping. You want to get the two part component version of Brightside for rolling and tipping. I learned that information from the marine painters, I live next to a boat yard. You can use a foam roller but there is more to it than that. You will find good videos on youtube showing a two person team at work doing this paint method. They are not using the same paint but the method is the same. Pay attention to what the guy doing the roller is doing to get the the paint more level for the guy doing the brush tipping. Remember to set up a small practice piece on a scrap of painted plywood to refine your team method before you start working on the trailer. Practice before you dive into the work, it helps prevent mistakes.

One part defianately works well with a roller or spraying. I've rolled a few FRP boats with great success. Spraying looks better , but that's true of all FRP boat paints that I know. When rolling brightside use a 4 in foam roller, roll it until it is sticky and keep a wet edge. The heavier you put it on the longer you must roll it. If you roll it until sticky it will not run but will flow out smooth. It will continue to shrink and smooth out for at least a day but you will notice a marked difference in an hour. Tip, nerve wax brightside, it has Teflon or similar product that rises to the top and will make it easy to clean.

PS, priming and sanding after and between coats is recommended. Tipping is not required or recomended, I found it works better without tipping with a brush. Call and talk to Interlux.

Here is a link to the application guide for the product. Scroll down and you will see the following statement which I have clipped out and pasted as an image (click to enlarge it) below this sentence for the convenience of not having to go to another website.

But the decision for using primer will depend on the surface condition of your trailer. As stated in the instructions you do need to prime crazed and minor crack areas (and of course over any filler). I did not have any crazing as such on my 1971 trailer but it is a different make. I did have areas with minor cracks also on the lower front there were lots of rock chips that needed filler and even a big hole to fill in.
