Vandals have caused big problem, need help

Hello Guys
A few of you know that i sold my avon to friend a year or so back.
He has had a few problems that we have overcome, mostly by reading stuff on this forum.

Recently he got a bad cut in the boat , and we have now got the right glue and just need to put the patch on.

But now some dirty little rotter has vandalised his garden adn thrown white Hammerite paint all over the place.
The avon has taken a lot of the paint, it was turned upside down so the underneath hull has a load on it and some of the sides as well.

Now ive been intouch with the makers of hammerite and they can only say that hammerite thinners might get some of the paint off but have no idea if the Hypalon would or could be damaged in the process.

Now i know this is very unusual, but if anybody knows what we could use to get the hammerite paint off without doing the rubber material any harm we would be very gratefull.

The boat was dirty before the paint got chucked on it so that might be a blessing.

we know its hammerite as the tin is still in the garden, along with a load more paint.

i think about 1/4 litre of paint has gone on and around the boat.

any help or ideas please let us know asap.
we dont know if the chemical reaction of the hammerite will destroy the Hypalon ??????

I would try some hypalon glue thinner as this wont damage the hypalon and may dissolve the paint. Keep it away from glued joints though

Worth testing this theory of course. !

Yes definately worth a go. Not sure if acetone will do much to the hammerite but certainly easier to try than the thinners.

Hammerite uses Xylene as its solvent. Same family as toluene so it might work.

The Hammerite thinners are very expensive but even that might not work once the paint has cured.
Best bet is paint stripper but be very careful what you use it on, not sure but it might just melt hypalon.

Standard cellulose thinners should do it just stay away from the glued joints get it from a motor factors not a diy shop anywhare that sells automotive paint should do

I ran a body shop untill recently & we used it for any vandle damaged vehicles we got in just get plenty on a rag & hold it onto the splashes to give the thinners time to soften the paint & cchange the rags once they are saturated with paint

the sooner you get to it the better as hamerite dries very slowly

definately would not use paint stripper it melts windscreen rubbers so I guess it will melt hypalon too

I am not convinced about your statements chemically

Xylene will act as a solvent for many things

According to the MSDS for Hammerite paint the solvent in the tin is Naptha - which is consistent with "petrol" being a possible choice. Their 'thinners' is roughly 50:50 acetone and naptha - so again acetone would not be a bad choice.

Xylene and toluene ARE chemically similar, although you could probably write an interesting (to me!) page on whether they are actually in the same "family" - however as a rule of thumb, if it dissolves in one it will dissolve in the other; and is also likely to dissolve in petrol too...
