Default 3m finesse II like glue

so after reading every thread here about detailing, I took the plunge, got the right machine, the blue pads from auto geek, got my light compound, my 3m finesse and rejex. I hand compounded the areas I was working on with no problem. I put on a light coat of the 3m with my blue pads and waited for it to haze. when I went to take it off, several areas stayed on. to the point I couldn't get the polish off so I applied more and finally got it off by applying prssure on the machine until it was almost all gone and shiney. My rejex when on and came off with no problem.

What did I do wrong with the 3m polish? Did I apply it too thick? am I supposed to continue to polish it with the machine until it's almost all off? I don't think so. Since the surface was compounded prior to the appliation of the 3m, it had a slick surface to go on so it's not like I was applying it to a surface that would grab and hold the material.

Somebody please help! At this rate it could take me weeks to do the whole boat. Thanks!
Tom

Tom,

I would say your first thoughts are correct, it sounds like the patches that didn't come off easy were too think\heavy.

I find adding a little more polish to a cloth and rubbing those spots by hand works better than trying to buff them with the machine, once you rub the excess off run over those spots with the machine again which will help remove any swirl makes from rubbing hard by hand.

A nice thin even coat will always give you the best results, just remember to do a small section at a time


Cheers
Daniel

Bubba,

The way it has been described to me, the Finesse-It II is a very mild, polishing compound. The more you work it with the machine, the
more the grit in the compound breaks down and effectively becomes a finer grit as you work it. I was instructed to use it with a 1500 to
2000 rpm buffer and a wool polishing pad, work a 2' x 2' or so area at a time, and work it until the product is completely gone and you see
a "wet look" shine to the gelcoat. As you did, prep the gelcoat beforehand with either rubbing compound or, if not too oxidized, Collonite
fiberglass cleaner (#925?), then follow-up with wax of your choice. To make sure I've answered your question, if done properly, there
should be no Finnesse-It II left on the surface after applying and buffing out - the surface should be dry and clean and have a "wet look"
gloss to it. Good luck, it takes me a solid weekend to do a 23' SeaCraft - don't know if my arms could take doing a 54' Bertram.

ok, so if I understand your comments correctly, I am putting it on with a wool pad and buffing it until completely gone, right? I guess I was confused by the instructions on the bottle telling me to apply it with a machine, let throughly dry and wipe off any haze. I was kind of following the same way I had always use compound or wax...apply, let dry, remove. Your way sounds a heck of a lot easier. Thanks for the comments!
Tom

Apply it with the machine and work it around until there is just the very slightest bit of haze or its gone. There will always be a little to go back and wipe up. My guess is maybe your hull is oxidized pretty bad and the Fineese It isnt enough. Its getting caked up on the rougher gel and then is very hard to remove. In my experience, Finesse is more of a final polish and doesnt work well for removing oxidation. It removes swirls and very very light defects only. My routine is 3M heavy duty followed by FinesseIt then NuFinish.

Hi, actually I had the boat wet sanded about 8 months ago and she has good shine. I used the white rubbing compound mostly to remove spider poop and diesel soot, so the surface is really decent. I think I just applied way too much.
Thanks for everyones help! I'll let you know when I get finished just how much fun it was!

Like Water Rat said, a wool pad at 1500-2000RPM. Use a heavier hand at first to 'work the material' and after a minute or so, lighten up and let the buffer speed increase and the material will disappear and leave a highly polished surface.

In your first post you say you bought the "right machine" - what is that? and a blue pad is not for correcting or compounds, it's about the softest pad you can get for applying final waxes...

Im not following why you let it dry? The instructions dont say to let it dry.
Work the material in, might just have to give it a light wipe when u are done but it doesnt get applied like a wax

Also not saying which product you used, finesse it ii is a line of products not a single product
