Topsides going from 'White' to flag blue
 
I am going to paint my topsides this spring (if it ever gets warm enough). I am going to use flag blue Interlux brightsides. I used Interlux Perfection on the deck, and had trouble if the conditions were not perfect. Anyway, my question is, how perfect does the prep need to be? My Bristol 27 has very fair sides due to the thick hull. There are some scratches I will repair. O/w, am I crazy to go to a dark color in a DIY (roll and tip) paint job?

Barquito,

I did a black paint job with roll and tip using Brightside. USE THE BRUSHING LIQUID! I didn't on the first coat and it didn't flatten out. I hesitated to use it as the day was in the 60's and didn't think I needed the thinning. Wrong. The second coat with the brushing liquid was gorgeous.

I was redoing a black paint job, not going over white, so you may need three coats. I did it alone too. I'd roll a couple of feet with a weenie roller and then tip, always keeping a wet edge.

I don't think you are nuts at all.

Go for it, flag blue is a great color, she will look a bit smaller but much sleeker. What color waterline?

Could you please explain what you mean by "tip".

"Tip" is going over the rolled on paint lightly with a good brush - it flattens out the roller 'stipple' and with the right conditions it 'flows out' to a decent gloss.

I'm going to have a gold cove stripe, and a white boot stripe. I think I might put the boot stripe a little higher than the original, and have a little blue between the white boot stripe and red bottom paint to keep crud off the white. Gold letters on the transom. All kind of old-school.

Just curious. Does a roll and tip paint job adhere better than a spray paint job? Anybody ever heard otherwise?

Don't think so... prep is prep, the advantage of roll and tip is that it's easier for a non-pro to do, you don't need the specialized equipment to spray.

I've painted a couple of boats with Awlgrip using a HVLP spray machine (the kind used to refinish bathtubs), I was satisfied and saved a ton of money but it was in no way a professional job.

Tommays on this site achieved an incredible finish on his Cal 29 with roll and tip.. much better than we got with the spray.

So many more variables when spraying. Hard enuf when when rolling! A perfect spray job is better than roll&tip. A poor spray job may be worse than a bad roll&tip. Plus, your two-part (linear) polyurethanes are extraordinarily dangerous when sprayed -- not a job for the casual amateur.

I HVLP spray single-part, water-based polys every day & can usually get good results. But the larger the workpiece, that harder that is to achieve -- and it took years of practice to become merely competent.:o One piece of advice, learned the hard way: once you find a finish brand that works for you and your situation -- reasonable to apply with the tools you have, nice appearance, good performance -- stick with it. Changing brands puts you back down on the learning curve.

Prep is the answer. You may see rib lines that you absolutely can't see when white. You really need to fair it out with a long board before you even prime. Good luck. Sounds like a really hard job.
