BM and Pro Polish- Midterm Grades

BM and PP last spring...this spring was just a touch up and it still shines like the day it rolled off the assembly line...21 years ago. SLW can verify that :-)
 
I used BM/PP before the launched it looked great for about two to three months than the topside started to dull and dirt seemed to stick and became hard to clean, the hull still looks great. Next year I will try BM and than Rejax if that's how you spell it. I have heard good things. When I pull the boat if I have time I'll do another coat of PP for the Winter just because I have it. It should make spring cleaning easier.
 
BM gets an A+, PP gets a C. I applied two coats of PP and started getting calking recently. Boats only in the water four and one half months up North. Boat's a 97 355MY Carver. Wiping off PP gets a A+. Not sure what I will try next year.
 
I dont find that PP gives much support to the BM. I love how BM works by itself, but I agree it needs something on top. Ive done two coats of BM this year and it seems to hold up better then putting PP ontop.
 
By saying "Ive done two coats of BM this year and it seems to hold up better then putting PP on top" indicates a misconception you may have with this product. BM doesn't go on in "coats", it is a buffing compound that removes oxidization and minor scratches. When complete, there is no BM on your boat, it is bare gelcoat, or at least should be. Maybe you didn't remove the BM properly before applying the PP and that is why it is not looking its best. If you just did BM with no polish you would have no protection from the sun and elements for your fiberglass, oxidization will quickly happen.

That said, if some of you are not pleased with the PP, may I recommend you try Aurora Boat Shine. Lasts a hell-of-a long time in comparison to some reports here. I do 2 coats in the spring, and the next spring when I go to do it again, I haul the wrap off the boat and people think I just polished it, when I haven't even started.

It seems to me though that most good polymer products will have a refreshing companion product which will rejuvenate the polish when it starts to dull a little and give it that freshly polished look again. I know Aurora has a product called Aurora Quick Shine, which is a simple spray and wipe. For the car I use Zaino, and it also has a spray rejuvenator. I'm surprise that the BM/PP products do not have the some sort of thing. I would think that the Aurora Quick Shine would work on top of the PP as well to bring back the shine.

I used BM on the hull before layup last year, hull still beads water.

If your boat is chalking up so soon, you need to use BM again and really polish out the gelcote until it look new.

Once it's back to like new condition it should take some time before chalking.
 
BM absolutely provides protection. BM only removes light oxidation. When you remove BM from the hull or topside it leaves the fiberglas smooth and silky and evenly clean with a deep shine. BM is a one step compound / wax, much like Garrys is but superior
 
I was under the impression that Buff Magic was a buffing compound. All it does is remove the top layer of oxidized gelcoat on older boats or used to shine up gelcoat on new boats. It's primary advantage is that it will reduce its grit the longer it is buffed; going from a medium grit to a fine polishing grit. When this stage is completed it provides no protection. It is up to the user to provide a layer of protection to prevent the gelcoat from oxidizing. I never used Buff Magic. In my opinion using a fine buffing compound should yield the same benefit on a boat that is not chalky. Once the gelcoat is shiny, there is no need for anything other than a polish and a coat of wax/polymer.
 
BM doesn't leave anything behind to protect the gel from UV rays and air pollution.

It does leave the gelcote soft and smooth but you have to put something on top of the paint or gel to keep it that way.

Even though the gel might look polish with BM, you have to run you hand over it to see if the surface is buffed down to remove all the pores that attract the dirt and chalk up.

A second round of buff magic with a fresh bonnet will do the trick.
 
So then when I said earlier that I put two coats of BM on Shel pretty much said I was wrong in doing so.

eh, whatever, no biggie. It works and it protects. I mean water still beads and I still have my shine. Thats all that matters
 
This is why I ask why not put a coat of wax over the pro polish, similar to the maguires three step process, which puts a coat of wax over the polished surface. I dont understand how adding a protective coat of wax over a polished surface is stupid and nobody that thinks it is can explain exactly why they have that opinion. Next year it is BM, PP and then a protective (noncleaner) wax.
 
After reading the responses to this post, Im starting to think that BM is useless for the majority of boats. Apparently, BM leaves no protection so it falls into the category as a compound. Yet at the same time its not gritty enough to clean a heavily oxidized hull, so then you'll need a heavier compound, with a wax ontop..

At this point id rather use Garrys.
 
Just to be clear the BM worked really
well on my boat. I was underwhelmed with the pp's
longevity but pleased with the initial results which gave the
thought to add a protective coating over the pp.
