Brightsides primer?

[ReelToy]

This is not about my SeaCraft. I have a 14' McKee that I use inshore and I'm fixing it up a little. My question is about Interlux Brightside paint. I have finished the out side of the boat and it looks very good. What was bad about it was Interlux Pre-Kote primer the stuff was very difficult to work with. It didn't dry properly and didn't lay down well also difficult to sand out. Probably humidity on the drying I used suggested thinner and right amount.I tried spraying and brushing it both and both were a pain.Do you think I could use a good outdoor primer like Kilz instead of Interluxs primer? Looked on web and they promote their primer with no reason giving.

Forget about that Interlux paint

Call Tom @ Signature Finish . You can get yourself a beatiful paint job without all the hassel and NO primer needed........

Signature Paints do sound good but I'm in a little to deep with the interlux. I'm definitely going to try it on the inside of my SeaCraft.

My bet is that the interlux breaks down the kilz and it all slides off. My experiences with Kilz is in the home restoration arena, and for that itz ok...there are certainly better primers and they're designed to adhere to more porous substrates than frp or vinyl esters. I'd check around a bit - you may find a less expensive compatible primer for the interlux but I don't think I'd mess with putting a $15 gallon of kilz under the pricey interlux product.

I agree w/ Gillie- I have used Kilz over formica cabinets prior to topcoat and also to change colors on interior/exterior walls. Also used it for sealing as well.
I also used a Glidden primer called "Gripper" on formica and fiberglass doors worked better than kilz.
Why did you have to prime prior to topcoat....did you have bare fiberglass etc????
I utilized Interlux Brightsides as well on my previously owned Seacraft and used their brushing thinner 333 with pretty good results.just worked a small area at a time..I did not prime..just sanded gelcoat and rolled and tipped. Durability was ok!!!!! Next time it will be signature paint or Awlcraft!!!! I would feel uncomfortable mixing and matching marine paint systems..but that is just me..I guess I dont know enough about the properties of the paints themselves to feel comfortable..

I sprayed the Interlux primer with a cheap pressure pot gun and the recommended thinner over gel coat and got good results. Temp and humidity are important. Sanding was OK. I think mixing paint products is a bad idea. I hate doing things twice.

I've been working with Interlux products on my seacraft. I'm using the primekote followed by the perfection. I had lots of issues with the primer too. I finally got decent results by just using the roller and not tipping. I thinned 25% initially (as recommended) and then rolled on. I added a couple of cap fulls of thinner to the pot as I went. I found that the primer went on very thin and it takes a couple of coats to build up a surface you can sand on a bit without burning through. Now I always roll on a coat, let it sit for 30 minutes or an hour and roll on another coat. This has worked pretty good for me. If I were starting out again I would probably roll on three maybe four coats to start with. You still end up with lots of orange peel and it takes at least 220 grit to knock it down. Sometimes I use 150 to start with. That primer is hard and a pain in the ass to sand. Hope this helps.

On a side note. I found that the perfection paint recommends thinning to a max 10%. I tried rolling and tipping and spraying and haven't achieved the results I want yet. Digging around on the internet I found the Interlux professional application guide. It stated thinning to a max 25-35% is required for spraying. That being said, its probably ok to thin the primer and/or paint more than the can states. I think thinning more would help some.

Actually rolling and tipping worked very well on the outside finish on the boat after a lot of work on primer. I thought about just painting the inside with just Brightside but a little worried because inside of the boat is blue and I am painting it Hattereas white.I would rather have primer white show through when I scratch it than the blue and I will scratch it.I will roll the primer instead of spraying this time. I'm not going to chance it with another primer I will use the Pre-Kote and deal with lots of sanding.Thanks for all the input.
