G'day fozy, Apologies for this slow response. When I bought my van it had a full-width sheet of aluminium across the lower front half... I accidentally put a noticeable 'ding' in the sheet during the trailer transport home. When I got near the end of the rebuilding of the van, I decided to cut that sheet down into two separate 'splash guards' for fixing to either side... I put a bead of Selleys Butyl Mastic around the perimeter of the splash guards, and then fixed them in position with pan-head stainless steel screws, making sure the slot in the screw followed the edge of the guard (ie. horizontal slot across the top and bottom, and vertical slot on both sides). The screws were spaced at exactly the same distances apart, when you look at top vs bottom, and side vs side. This gives a much neater visual appearance.
Using butyl mastic means the guards can be taken off easily if that is ever necessary. Using sikaflex means they'll be damaged if you ever need to remove them. cheers, Al.

You mean you dressed your screws Al? A very important part of keeping up appearances. The Butyl Mastic is a good suggestion. I have just had 2 pieces of aluminium cut & rolled (using original front wooden panel as a template) We have been discussing this very same topic & are going to use short slot head screws & some sort of adhesive. Some examples of past projects; Phoenix with stucco aluminium, presume we used sikaflex if anything? Not sure where the rubber edge came from either. Bondwood Viscount, aluminium sheet copied from original stone guards. I think it's nailed top & under j mould but not down the side? (will have a look later)

G'day sgtl,
I would avoid using anything classes as an "adhesive" to fix the guards, unless of course you want to do it without using any fixing screws. The benefit of using butyl mastic is that when it comes time to repaint the van (in 10 years), you can easily remove the guards and clean up the butyl mastic sealant with mineral turps before preparing the van for painting. Then you re-fit the guards the same as before.
If you use any of the sikaflex-type adhesives, they will need a jackhammer to break the adhesive bond, destroying the guards in the process.
The downside to butyl mastic is the current price of the product - $26.99 for a 400g cartridge from Bunnings , but it is available in white, grey, and black (I used the grey colour to blend in with the edge of the aluminium better. When I bought it 4 or 5 years ago, it was around $19, so prices have gone up a fair bit since then. I used the cartridge for the splash guards, and to seal the port-hole windows before I fitted them back into the van. If the nozzle on the cartridge is cut to give a 5mm diameter bead of sealant when you pump it, a 400g cartridge will give about a 3 metre length of sealant )
There are cheaper brands of butyl rubber/mastic cartridges, but they are only available in white...
Selleys also have a D-Mastic product ( here ) available in white or black, and is half the price of their other Butyl Mastic. However, I've never explored this product to know whether it would be suitable for use in our caravans.
You could also explore the use of butyl tape (example here ), but again I've not done any research on suitability.
cheers, Al.

Hi Franklin1. I've only ever used the Selleys Dmastic and found it quite good. Hard on the outside, but soft on the inside. Have used it for the stone guard as well as corner edging.
