Is this True ?

[tillybobs]

I heard this down at the maarina today as I was getting ready to paint my hull...."international brightside is not as hard wearing as a two-pack" ie the fenders will wear the paint away quicker than it would with international brightside as I was going to use this would I be better going for the two-pack? Thanks in advance

Perfection is much more durable than Brightside. All two-packs must be applied to bare glass or two part primers. They can not be applied to any surface that already has single part paint...

Two parts like sterling are much tougher. Brightsides wears quicker but is much easier to apply and much more forgiving. Not to knock you or pre-judge, but honestly if you're asking the question I'd stick with brightsides and move up to two parts like sterling over time.

Hi Thanks for reply I will look into Perfection I didnt think it would make that much difference.

IMHO nothing beats a two part poly. My own best gelco but once gone it is time for a two-part.

No I don't mind being knocked or prejudged after all I did ask a silly question. I think I will start off with brightside and then move to two pak over time

If want that shiny wet look, and the nervous attitude that accompanies it, and the huge expense, go with the two-part. Not done perfectly it will peel off in sheets.

I'd use Brightsides on anything but a 'show' boat. You can paint her 6 times with Brightsides for the work and cost of the two-part. And repairs are trivial.

No it won't last as long at the fenders. Avoid fenders at the dock. Hold her away with lines if you can.

Hi you are right. I could get someone to spray 2pak on hopefully for a good finish but as you say repairs would be difficult but fenders are unaviodable where it is at the moment as it will be moored in a canal maybe with other boats alongside

Here's a starter if you'd like to learn more about Perfection:

Be advised; the paint doesn't cover ANY imperfections...the hull must be smooth as a babies you-know-what!

Good advice!

And if you can't hold her away with lines, use at least twice as many fenders as you need.

LPU's cost on average 3 times as much as modified alkyds like Brightside. A gallon of Brightside is about $100 retail, while AwlGrip will run $270 to $330 retail depending on color, while other brands, like Sterling can $310 - $350.

Yep, the LPU's are more scratch resistant, harder, have higher gloss retention, etc., but you have to pay for it. Additionally, LPU's are not especially user friendly for the novice painter. So, if you've got some experience with converters, wetting agents, accelerators and the like, typical of two part linear polyurethanes, then go for the good stuff. If this seems a bit overwhelming, then stick with plain old alkyd paint, where all you need is some spirits and possibly Penatrol to "flow" things out. In all honesty, recent advances in modified alkyds have made them very good. They flow out great, you can roll and tip to nearly a spray like finish, they're harder and more durable then ever and they can be buffed to nearly LPU standards, all at 1/3 the cost of an LPU.
