WhiteCheyenneMan Posted July 20, 2013 Share Posted July 20, 2013 I have some black and brown spots on the GRP bodywork of my MH and have had some success using Autoglym Tar etc Remover. But some won't budge. I can loosen some with my finger nail (I know that's not a great idea but it shows that they are removable) and then the Autoglym removes the rest...........sometimes!Anyone have a better infallible suggestion?

Basil Posted July 20, 2013 Share Posted July 20, 2013 If it is tar based, I use WD40 sprayed onto a cloth then placed against the spot for a few seconds and then wipe away with said cloth. Don't forget to polish after not that WD40 does anything but road dirt is attracted to the WD40 residue and looks quite dirty. Bas Link to comment Share on other sites More sharing options...

Some are tar and some are probably fly and spider poo. But, can the ones that I can't budge be any of those? I don't know, they all look alike, but some come off and some don't. Someone has suggested that it's because I only use a wash and wax shampoo, when I should wax polish it regularly and then these spots won't stick so well. Maybe, but the area to polish is half a football pitch 8-) Link to comment Share on other sites More sharing options...

It must be this warm weather but I had quite a few tar spots (mainly on the drivers side) on the start of the coachbuilt body just behind the cab doors.

WhiteCheyenneMan Posted July 21, 2013 Author Share Posted July 21, 2013 We're beginning to get somewhere, it's a team effort. The Autoglym Tar etc Remover has turned some to powder overnight and today. Many are now dissolving under water and washing up liquid. It's going to take a few more days of soaking and wiping, followed by a good polish methinks ;-) Link to comment Share on other sites More sharing options...
WhiteCheyenneMan Posted July 27, 2013 Author Share Posted July 27, 2013 I should start by saying that I did wash to MH first and then discovered that these spots remained. The Autoglym was very disappointing, even on what was clearly fly/spider poo.The key issue is that we had only wash/waxed previously and never did a full scale polish. So these deposits stuck well and hardened. It's doubtful that the Autoglym did much at all although a few spots did succumb, in part, to repeated applications.The solution? A very strong solution of bio-washing up liquid and water applied with a dish washing sponge and occasionally a light rub with the rough side of the sponge.Next job a thorough shampoo followed by a resin wax, applied by electric polisher, but first, the thunderstorms Link to comment Share on other sites More sharing options...
Bolly1965 Posted July 27, 2013 Share Posted July 27, 2013 I found some mysterious brown spots on my car..... eventualy discovered that the wooden fence by where I park my car at work had ben painted with shed & fence paint - even though it was water based it was a swime to remove. Bug and tar remover is ok but WD40 shifts most things better Link to comment Share on other sites More sharing options...
Guest Peter James Posted July 28, 2013 Share Posted July 28, 2013 I keep a bit of petrol for cleaning - shifts some stuff, like tar, that nothing else seems to. As a last resort cutting compound (like T cut but coarser) should shift it because it scours a thin layer of paint off. Link to comment Share on other sites More sharing options...
