I've been doing quite a bit of researching over the past month as my chim is my only car and will be driven daily over winter. It had its outriggers replaced a few years ago but the paint had started to flake away, it was non existent in the front corners, the metal was still perfect though as it was only a dry use car before I got my grubby hands on it.

I did the usual and bought the epoxy mastic paint from ACT but couldn't decide on how I was going to protect it beyond that, after lots of reading and looking at many threads on classic car builds I went for Dynax S50. Its much better than waxoil etc as it flexes and stays slightly rubbery so doesn't flake off.

I've never been so impressed by something that I've had to start a thread to tell random strangers about it before, honestly it's the nuts. It's like spraying melted chocolate out of a can and there's a hose attachment to feed all the way along the top of the outriggers from the corners, it was dripping out from there so they were definitely all covered on top.

Judging from the difficulty I had getting it off of my hands it should more than last the winter, apparently it can be removed with a solvent cleaner if you ever want to check under there and repaint. I bought two cans but managed to cover the outriggers and have a bit left over for touch ups if I need to with just one can.

Couple of pics just for the sake of it, I painted it last weekend on the lift at work but did the dynax outside today..

That looks good stuff. Just doing my outriggers at the moment and that looks better than the waxoyl I was intending to use!

Out of interest, what's the rough geographic location of the company that did the outriggers? Mine (well, the whole chassis) was done three years ago and the powder coat has all flaked off terribly as well.

I have no idea to be honest, they were done two owners back and at least 6 years ago but I do know that the car lived in Portsmouth at the time.

So far the most mine has had stuck to it is what I would describe as grains, what was there brushed off with my hand. It's still looking good and hasn't flaked off or anything yet thumbup

daren , I haven't applied this product yet but will only be putting it in the area's that you cant get to
successfully "rear outriggers" and possibly the tops of the tubes above the body
the aerosol comes with a 600mm extension tube so i'm hoping this will enable the product to be applied everywhere
and cover areas that you cant see as I think its quite runny and will creep under the corner plates as well
i'm sure gravel and dirt will stick to it and not look to good but its there to do a job I hope

I will apply a thin film of dynax to this area on a regular basis to keep the tin worm away
