Under wheel arch protection

[Rob Waldron]

Is there any rubberised paint or liners owners use to give a bit of protection to their mudguards underneath.

I use this product from CBS.  However, unless you put very heavy coats on a stone will still cause a star crack

Another vote for 'Wunderseal" and yes indeed, you do need to lay it on very thick then stipple it to create a really rough 3D textured surface for maximum protection. It over-paints pretty well too if need be. Expect to dispose of any brushes you use to apply it! It dries very quickly when applying it so be warned - you can't hang about.

 

Rear arches in particular had lots of pretty bad star cracks after 20 years so when we had the car painted, I put a thick layer of Wunderseal under all the arches. No new damage seen in the last 10 years.

 

 

I had a spare unopened tin after doing the Westy in 2011 and unsurprisingly it had gone off a bit over the 10 years in between. I rescued it with some cellulose thinners. Added a bit more every so often and eventually it got soaked up to the point I was able to start stirring it. Got it back to full usable state and applied it to all the arches of the Midlana.

I used Dinitrol 449. I've written it up in my build diary here and on some subsequent pages. 3000 miles so far with no issues on the rear arches so not a lengthy test yet.

Thanks for the tip, how much did you use. I was mainly for now going to do the four wheel arches but quite like the idea of the added protection underneath.

I have use this brush on "Herculiner" truck bed liner on the underside of my fiberglass and carbon fenders (wings, mudguards) with great success. I've used 3 coats on my carbon front fenders and even with my super sticky slicks throwing up every stone on the planet I've not seen any cracks or damage from underneath.

 

The rubberized nature of the stuff also reduces the noise from rocks being thrown up at the fenders. I nice side effect.

CBS only do one size of tin 1kg, ample for all 4 arches....

I have heard good things about "Herculiner" on some of the other kit car forums and also Duplicolor Bed Armor.  Apparently, Bed Armor is more user friendly as it cleans up with soap & water whereas Herculiner requires Xylene...so I hear! 😁

Just the one litre tin, but just did the front wings and under the rear wheel arch
