    underseal

    Hi guys

    could someone let me know what is used to underseal the wheel arches and prevent stone chips to the fibreglass.

    Whatever is suggested will need to be brushed on as the car is just about finished.

    Products and sources of supply are welcome

    Regards
    Dave

    Re: underseal

    This sort of thing has been around before. Most people, including me, used an ordinary roof sealant from places like B&Q or Homebase. The stuff I used is called Liquid Rubber (from Homebase) and is harder to brush on than marmite from the fridge.

    Cost is about 10 for a 1 litre tin.

    Cheers,
    Tony B

    Just done my wheel arches yesterday - I used rubbercoat which you can get from kit car shows. If you want the company's contact details let me know. It was pretty thick stuff once I'd stirred in the treacle at the bottom, but easy to stipple on with an old short-haired wall-papering brush. I'm hoping to see it nice & dry tonight - absolutely stank the garage out even with doors open - I needed a heavy duty mask and marigolds to put it on. Aklso, so far I can't remove the marks on my upper arm even 24 hours later! - it contains cyanoacrylites, as found in superglue, so not surprising, sticks to anything. Its covered up all my fibreglassing efforts and makes it look like a proper car under the arches now!

    cheers

    Kevin.

    Keep spraying with water from a plant mister, it does speed it up (a bit)!

    Re: underseal

    thanks to all that replied.

    I used a product called liquid rubber from B&Q, went on quite well, and dried after a couple of day. Messy to apply so you need to cover/masl everything of on a built up car but other than that a job well done.

    Regards
    Dave
