Polishing inner hull location for Wetbox

[Smelly]

Hi Team!

I am installing a wetbox - ducer in my fb hull and want to know if I need to polish the inner surface of the fb of the wet box area to obtain better signal..?

If so, what pad and what max speed should I use? Can ii get away with a single speed drive polisher?

I love a good wetbox, any excuse to introduce 'wetbox' to the conversation. ;D

seriously though, why would you need to polish the FG to install a WETBOX? if it's all air bubble free at the interface there needn't be any problems.

only reason I can think of is so the WET medium bonds to the glass.
if you use industrial sika or silicone, it'll stick like the proverbial sh!t to a blanket.

grand marlin (Pete) is clued up on this stuff - Pete, you there?

Yeah Steve,

I'm here ...

I get a pm from smelly which I answered pretty much the same as you said here.

I also assumed that fb should be fg, meaning fibreglass?

Cheers

I will just add one other thing smelly, if you are really unsure ... throw someone a carton who knows about this stuff and get 'em to have a look and steer you in the right direction.

Cheers

..... and I just saw your other post re: wetboxes....

Smelly, you are hard to keep up with .... you're gettin round these forums like a stray dog with a tin d!@k ;D ;D

I think I gave you my number in a PM ... call me if you need to.

Cheers

THnaks boys.

Gelsec - do u like fishy wetboxes. I like 'em bloody! :P :P

I spoke to the pros (up the street) who do this for a living and they always polish their wetbox area - soley for clear signal transportation echo through the hull..I think

I even offered them money to come and visit me but they did not want to know. I had to take my boat to them and pay copius $$ no doubt.. :o :o

Should I polish for this reason (clear signal transportation echo through the hull)?

What other treatment (of the hull fiberglass) should i consider on the surface before I bond the wet box on?

Hi smelly
I will chase ya round the forums.
Me I wouldnt worry, although I have just fitted a transducer to the floor of a tinnie under the rear thawrt seat and I did give it a light rub with 320 wet and dry purely to clean the surface to get a good bond.
When you say "wetbox" are you fitting it in a fluid filled container or just sticking it straight to the floor of the boat.

"wetbox" = fitting it in a fluid filled container - in my case.

What do others think - should I polish the surface of the fg where the ducer will be transmitting signals?

THis ducer will not be buted up against the fg - but rather held about 70 mm above fg..

::)

DO i applyy the acetone before I scuff the fb or after?

[Smelly]

Well,

I finally got there.

Perfomed the operation with first bead of sealant waiting to dry. I then apply a second, maybe thirs bead in the coming days....

Can't wait to use the M260! ;)

THanks GM and others
