Priming for Interlux Brightsides?

[Boomyal]

I'm getting ready to spray the back end (aft section behind rear seats) and bilge of my boat. I will be using the above paint in white. All of the glass will have been sanded with 60 or 80 grit paper and washed with acetone.<br /><br />The paint dealer, a paint specialty shop, says that I don't need to prime it under the circumstances above. Of course it won't be underwater either (unless I forget the plug )<br /><br />What I do not want is to have this paint peel down the line. Also I'd rather not have to go in and spray the primer then go back and resand the primer before the topcoat.<br /><br />Any opinions on this???

Re: Priming for Interlux Brightsides?

Great topic. I went through exactly the same issue. 1/2 of dealer told me i'll need to apply primer, and 1/2 told me just undercoat (prekote in your case) 2 coatys and apply topcoat over it. In the end I applied primer 2 coats, undercoat 2 coats and 3 topcoats. I had peice of mind, but a little less money. I'm interested in what people answer to this one, as I couldnt get a straight answer from anyone.<br /><br />Cheers

Why take a chance? I would use the primer.

I didn't prime usimg that paint. I rolled and tipped and it came out great no peeling or anything yet (this is only the second season though). If it's good and clean it seems to stick well. However, I painted over gelcoat...

We are priming ours. You can put down two coats of primer fairly quickly as it dries fast. It is worth it not having to worry about it. Also, with the primer coats on, you can see little imperfections that you may have not noticed before and have time to fair them out before the final paint. Just my thoughts.

Keep in mind that this area is going to have virtually no traffic, be out of the lite and not sit immersed in water. I'm not real concerned with imperfections as you would on a hull<br /><br />Years ago I had some fiberglass patchwork done around some splitting glass on the motor mounts. The vendor painted all the new work and the bilge probably with black enamel. It did peel but I could see that the glass had not really been ruffed up and I'm sure the black enamel did not have the snottyness that Interlux has.

My opinion is primer is cheap insurance just in case of what could happen and after all your hard work why be cheap now

Re: Priming for Interlux Brightsides?

You don't need to prime if the glass is prepped right. There is nothing to worry about and you aren't taking a chance by not using primer. This isn't like metal priming and you don't have a poor surface with old paint (compatibility) to deal with. Lots of people, including myself, have done it for years without problems...same as Petit Easypoxy.

Hey Boom, just out of curiosity, why not gelcoat?

Ralph, gelcoat is used in a mould in the manufacturing process, or for patching a moulded product. Chief

Hey Boom,<br /><br />Good choice of paint! I really liked it. I used pre-kote under the brightsides and the 2 part primer under the interdeck...looks and is holding up great.

Good question Ralph in view of the fact that I believe that is what the factory must have sprayed in the aft area originally. It was a very light coat over the extremely rough hull weave and unsaturated side flooring. It was not glossy and attracted a lot of dust/dirt etc.<br /><br />I never considered it because I was unfamiliar with it's application and because all of my new work is done with white pigmented epoxy not polyester.

It can be difficult to get a good bond when painting over a rough bilge area with any type paint, gel coat or epoxy. All the old gunk that sits in there like oil, gas, bait, suntan lotion, beer, soda and fish contaminate the surface so bad that it is hard to prep it correctly. If the surface is rough you can't sand the low spots where the gunk is easily, so these areas don't stick well, if you sand it smooth then there is no problem. I normally use a very stiff wire brush and waterless hand cleaner, its the best stuff I've found to clean a bilge. The wire brush will get into the low spots.

And I don't normally use a primer.

Re: Priming for Interlux Brightsides?

Chief, Gelcoat is also used as the final finish. Done right it wears well, looks good and lasts decades. It is easier to apply than paint (doesn't run or sag as easily as paint). Also acts as a filler (within reason) and can shine like a star if properly finished. It can also be used above or below the waterline unlike these one-part topside paints (trust me, I used it on my swim platform and it didn't even last a light season). Now I have to strip it and gelcoat it...<br /><br />Boom - West Systems say no problem using gelcoat over epoxy. You have to make sure the epoxy is fully cured and you have to remove the blush before gelcoating. I've since read were other epoxy makers say the same thing. In West's advanced video they actually gelcoat over a side hull repair and by the time they finish you can't even see the repair.

Re: Priming for Interlux Brightsides?

As I posted yesterday, I primecoated the interior in anticipation of applying the first coat of Interlux Brightside today. The Briteside went on smoothly and wetted out well. Interestingly, I had enough left over to do a storage compartment that I did not have enough primer to do. My own observations was that on the unprimed surface the paint did not wet as as well and that it will surely take another coat to cover completely. I could probably stop with the first coat over the primed areas, but I will put on a second, flattened coat anyways. Mike
