I need to better adhere the rear window protector

Gday John,
I like the genuine "Velcro" brand stuff. Buy it in boxes of hook or loop with one meter lengths at Bunnings.

Self adhesive Velcro is available in various widths & strengths so perhaps you need to get something wider to give more surface to stick

I use velcro a lot to attach things to my Achilles inflatable boat & the wider the velcro the better

Regards Don

There are 2 types of adhesive, one to just hold the velcro in place prior to being sewn, & one intended for semi-permanent use ..... but, any of that type of adhesive will progressively lose its grip as heat increases.

Hi John,

I use the standard Velcro Hook & Loop spots and the adhesive backing has proven to be adequate.

The original strip Velcro as supplied by Obie's lasted around 6 months on the glass, then started to lift with contraction and expansion.
This adhesive was water proof but proved no better than the normal.

The spots don't expand or contract like the longer strip material.
I noticed during our Innamincka trip that the original Velcro on the screen has lifted in places, so I will replace this with the spots as well.

One little tip. Due to the Loop material already being attached to the screen, I had to put the Hook spots on the glass. These broke down over time with the ultraviolet rays, but was easy and cheap to replace.
When I renovate the screens I will place the Hook spots on this and the softer Loop spots on the windows. This will also be kinder to the sponge when washing the windows. The screens are not permanently out in the sun, unlike the window glass.

Hi John, I had the same issue with the Velcro dots and strips - didn't matter which brand. I now use the 3M brand 'Dual Lock' strips and they are great. The adhesive is waterproof and heat resistant and they have small black mushroom shaped plastic stems that snap together. You can get it from Bunnings for about $9 for a pack of 4 strips. I've had it on the back of the Patrol now for over a year and they look as good as the day they went on.

Why not just a few dots of silicone?? Very good adhesive- and no problems to scrape off when not needed !!

Hi John.
Just returned from a 3 week trip out west. I had my protector attached with velcro strips & they lasted 1 day!!.
Used silver race tape. No problems. Protector stayed in place & cleaned off the residue glue white spirits when I got home.
The velcro stickers were a waste of money in my opinion.
Cheers.

G`day John,
I used stick on velcro to hold canvas dust covers over the fridge vents on the caravan but they didn`t last very long before the velcro came unstuck from the plastic vent cover and they started to peel away.
I made a rear window protector for the Innamincka trip from a sheet of 2mm Polycarbonate (spelling ?) and fitted it to the window by drilling holes in it to hold six 60mm dia suction cups then used another six smaller,40mm dia, suction cups in the spaces between just stuck to the window, not drilled or held to the protector, to hold the it away from the glass a bit more evenly. It didn`t move for the 4600 + K`s .

Regards,
Scrubcat.

3M make one that is excellent.

Hi John

Their are significant specification differences in the many grades of Velcro available.

In the design of the new Southern cross station I specified a type that has little sag when hot and under load for some small fixtures.

E.G. PS 0172 loop and matching 19mm wide PS 0172 hook
