Re: Painting Question, if I may?

IMHP it is never a great idea to use wax on something your planning on painting in the future as the odds of getting it all off well enough on 100% of the topsides are not that great

Re: Painting Question, if I may?

Wax on exterior painted surfaces is the normal sacrificial protectant. If you don't use wax, you use a polymer polish or other material which is harder to remove. Or you leave the paint bare and UV breaks it down.

So the cheapest best solution is to use wax, and then when you want to repaint, that's why the good lord invented PrepSolv and terry rags, so you can strip the wax off easily and completely, the way that every paint shop does with every car, boat, and plane for every repaint job.

Re: Painting Question, if I may?

How does the wax stop UV from deteriorating one part paint ?

Don't be fooled by some companies that lead you to believe that it is the UV protection in a wax that protects your car's finish from fading and failure, this is dishonest and simply not true.

I never see anybody wax there house ?


Its a one part paint past it lifespan that is not hard enough to be buffed back to a gloss

Re: Painting Question, if I may?

House paint isn't a gloss paint. And house paint does break down, does chalk, but it is a very different product from what is used on cars boats and planes. Or do you think the paint makers are all lying when they say to use a wax (or proprietary material) for routine protection? The hull makers all lying about protecting gelcoat? The chalky gelcoat you see on unwaxed hulls, just coincidence?

Re: Painting Question, if I may?

Back in the day I used to paint my hull with the local building supplys best polyurethane porch & deck enamel, roll and tip. Worked pretty well, shiny, and fairly durable, three years anyway. The price was certainly right since it didn't say "marine" on the label.
Also, I think it's "Pyewacket".

Re: Painting Question, if I may?

IIRC Pyewacket was also the name of Walter Chronkite's yacht.

Marine topside coatings (they'd send out a hit squad if I used the "p" word) are generally supposed to go 10+ years between resprays, so if you were getting three with household deck paint...I guess that works if it is cheap enough, or you like color changes.

Bite the bullet, and do it right. Take off the old crap, put on proper marine paint - Interlux one or two part coatings, and they have superb support and videos to teach you how it's done. By the time you finish screwing around with these half baked solutions, you'll have spent as much time as painting your boat, and STILL be no further ahead.
Tommays, that's a beautiful finish, far better than the last job I did. You should open a thread on this and give us all your secrets!

Hey, you got me wondering, so I went and looked at the back of my boat. Yep, it's "Pyewackette".

Re: Painting Question, if I may?

In case anyone is interested, you can buff/wax 3 year old alkyd enamel paint.

I first wet sanded with 600 grit and then high speed buffed with 3M Restorer and Wax Step 1. I probably could have done a better job if I would have started with 400 grit and stepped up to 1200 and then buffed with the 3M. But, I wanted to do it fast and I am planning on repainting next haul out anyway.

One thing I did do, is paint the white boot strip and bottom first before applying the wax.

Re: Painting Question, if I may?

Some urethanes work over old , time hardend, sanded alkyde, without softening it. Try a small patch.
Wax eliminates all future alternatives, except stripping it all off, and starting from scratch, a huge and uneccessary job.
