Does wing-top chequerplate usually have any gasket, or is it fixed direct?

I have birch trees by my house which shed tiny seeds in profusion that get everywhere.
I have today removed the chequerplate from the NSF wing of my 300 Tdi 90 CSW to clean out the heater intake box (which had two good handfuls of sludge and seeds and a blocked drainage hole).

The chequerplate was mounted direct to the wing-top although I have heard owners talk of having a neoprene gasket between them. The wing-top was wet underneath the chequerplate (unsurprisingly). The paint underneath the chequerplate was all original and in good condition. Should I fit some kind of gasket (e.g. thin neoprene) between the two? What have others done? Any suggestions re. gasket material and suppliers if that is deemed the preferred route?

I'm planning to fit a snow (seed?) cowl to stop the heater intake box filling up again. The OSF wing will also be done next, but that is just for general cleaning along with fitting new black anodised marine CSK screws.
Thanks.
 
Mines on directly (ie no gasket/sealant).
I don't plan on taking it off to be honest ....

Chequer plate - to gasket or not to gasket

Will be fitting the CP to the wings, sills and rear quarters this coming week and been looking at getting the gaskets for under the wing top pieces. Is it worth it? or will a bead of the good old silicon sealant do the job? Will be fitted with rivnuts and bolts. anyone tried it with silicon? If...

Chequer plate.

my first post ! Was thinking of putting some chequer plate on the wing tops of my 90 hardtop ( 2011 ) are you meant to put any sealant or gasket between the bodywork and chequer plate to protect the paintwork, I know it isn’t going to get seen again but I like to do a job properly Cheers.

My 90 has a pair fitted and a snow cowl. The chequerplate isn’t sealed that I can see and certainly doesn’t have any neoprene gasket. It is riveted on. You could always run a very thin bead of Black or clear silicone sealant around it when refitting.
 
Thanks.
A post in one of the threads linked by @miktdish suggested running a thin silicon bead around the CP panel and then letting it cure before fitting. This seems a good approach. The only objective I really have is to stop there being a permanent 'water sandwich' between the wingtop and the CP (I know they're both aluminium, but it just seems wrong!), but I don't want them permanently glued together.

Paint the underside of the checker plate panel with a rubber roof sealant let set then fit if your worried or just give it a coat of thick gloss paint but dont use a seperant membrane...
 
No Gasket, they hold water.
No Sealant as above.
Just Riveted in place, ( Stainless marine grade rivets) simples and easy to remove if needed etc.
 
Why not silicone the alloy plate, then a thin smear of grease where it touches the wing, that way silicone will seal the gap and the grease will stop the silicone sticking to the wing?
 
I used stainless countersunk bolts on mine rather than rivets. but agree with the above that straight onto the wing is the best bet. I would use any form of gasket or sealent. the reason being is that unless everything is perfectly sealed water will still get in, and if you have selled it it will not be able to get out. If you just fit it with nothing water can get in but it can also just as easily get out again and as it is all ali then a little water flow wont do any harm!
