I'm going to the local auto finish place today to buy some more Presta Ultra Cutting Cream. I also need some more Collinite 885. This place said they don't have it because it's marketed exclusively to marine stores, but that their 476s is exactly the same thing, just packaged differently and marketed to auto shops. Looking over Collinite's website, it does look like the two do have the same balance of properties:

FAQs » Collinite

I think the 476s is sold in 9 oz and 18 oz cans, while 885 is sold in 12 oz cans.

I can't pull down their SDS online, but one blog says that the two SDSs are identical. However, that's not a guarantee that it's exactly the same because SDSs generally only disclose a range of ingredients, not the exact composition.

It auto place is only 5 minutes from my house, plus I'd like to do business with the little guy where possible. I also expect that automotive prices might be a little lower than West Marine, though I have not verified that.

Have any of you have side-by-side comparisons between these? (PDQ/Drew or MainSail?)

Do not wax or buff awlgrip. Wash it. Don't scrub it either... if you scratch the surface, you're going to be screwed. :)
Okay, dumb question #100....How do you know if the hull has been to the awlgripped if you just got the boat and the owner prior to the one you purchased the boat from did the work?? It is spring and I want to know if I buff or not.....

Pretty choppy sentence, but I think you're asking how to test whether you have a polyester paint like Awlgrip or an acrylic paint like Awlcraft.

Find a less obvious spot, such as under the transom. Dampen a contrasting colored rag (white for dark colors, dark for white colors) with acetone and rub on that spot. Polyester paint will not color the rag, acrylic will. Don't rub so hard as to take the paint off.

Thanks and sorry for the poor writing...my kitten was helping.

Why over think it? Why mess with a proven thing
I just finished waxing with Collinite 885 and following Mainsails program as I do every time I wax

Jamestown, and auto wash have it at $20 with Defender ..no tax..free shipping at $18. How much cheaper will you find it..pennies? I keep a supply of this in my dock box. Also have found "deals" on it in bins at the Annapolis Boat Show" where I have gotten it for $10 a can. It's great stuff . I don't need a side by side comparison over a proven product. Why risk it...it's just wax.

I purchased a gallon of each of the Presta products in 2010. I use the Ultra Chroma each spring to restore the brilliant sheen.
7 years later I find the product becoming watered down - spraying all over. Spoke with Presta this morning and they said the shelf life is only about two years.
Long story short, I poured the product into a bucket - wiped it onto the hull with a wash cloth - the results are just as excellent as in 2010 - and without any splatter.

Tried my first full blown compound and polish today, we were both (me and the materials) too hot, baked by the sun and drying out too soon, so Im not sure I learned the things I needed to learn but it looks better than before by far. The body shop guys of old would tell you not to polish outside on a hot day. I'll haul earlier next year.

Be sure you have a spray bottle with lots of water. Spray it on every few minutes.

This Fabulous post was done in 2009. Do you still recommend the same products now that we are in 2017? And, what process would you recommend for Awlgrip stripes on hull?

I touch up my hull every spring using same products. Hard to improve on what’s been shared. Good luck!

What an amazingly detailed post. Thank you for sharing!
I just polished my hull with 3M Perfect-It 36105 Gelcoat Medium Cutting Compound/Wax. I was happy with the results, but it was definitely far from this incredible level of gloss. I think I'll take another shot at it next spring and maybe get it a little closer to something as amazing as this.

I put my last coat of wax on the boat 4 years ago when I switched to Poli-Glo, which only takes me about a half hour to apply and looks fantastic all year long. This year, I'll strip the old coats of Poli-Glo from the hull with their special cleaner and begin anew. A friend of mine did that last week and his boat has a mirror finish now.

Good Luck,

Gary :cool:

How important is variable speed on the buffer? I don't have electric where my boat is currently stored so looking at a Ryobi battery powered buffer, but it's single speed (2500 rpm). Is that too fast? Oxidation isn't that bad, and the boat is only 24 feet so I don't plan on going all out, so maybe it's ok? Or is a single-speed so bad I should consider a towing the boat to a different location to do it? (or finding a generator, I'm not spending $800 on one..)

edit; nvm, think I'm ditching the idea of battery powered buffer. Gonna try one of the cheaper $400 generators. Also useful for power washer and other things.

2500 is too fast - that's sanding speed.

For buffing & polishing you want about 1/2 that - 1200 to 1400.

In my experience, electric power washers are almost worthless. Even a high power gas washer isn't as effective as a brush or wiping with a sponge. The only reason to use a gas power washer is ergonomics - you can wash the slime off the bottom of your boat in a standing or kneeling position, much more comfortably than brushing/wiping your boat's bottom from underneath, with slimy water dripping all over you and running down your arm. But for topsides, a pressure washer is far more trouble than it's worth (and can damage the gelcoat if you slip up and get too close).

Back to the main topic, I'd check the power needs of a plug-in buffer and consider an inverter. If a little plug-in one won't be enough, but they make bigger ones (400-600 watt) that can clamp onto a car battery. If you're on the hard, you could run your car motor to juice the battery while running off the inverter.

You do your cut polishing by hand?

I usually do my waxing by hand but not the cutting compounds.

That sounds a bit intense.. I don't have power where my boat is now so I'm trying to find a way to use a buffer without spending $400+ on a generator just for that purpose. But don't think arm muscles is the answer. Maybe I just do full buffing in the fall instead.
