Exhaust & Paint.

[bullet5]

Tis just a quicky. About a week ago I stripped my Gilera's exhaust, and repainted it with PJ1 Exhaust paint. I ended up using about 1 1/2 cans of the stuff, and put on a good few layers (5/6 or more on some areas).

I took the bike out for a ride today (first time since fitting the newly finished exhaust). Once I returned home I checked the can, and it had a few specks of mud on it (have to ride along a mud track to get to garage) I decided to let it cool, as i didnt want to burn myself. Came back to it, sprayed on my muckoff, then tried to wipe it off, and the damn thing has (what appears to be) eaten into my paintwork! I can't get the marks off at all.

Really peeved off as I've spent time and cash on getting the finish just right on the can and it's ruined. So what can I do now?

I could, (and probably will) but it'll happen again, and again.

you will find that you have to run the bike to make the paint go off properly and leave it to cool to harden

you only have to leave it on idle for a bit to do this not actually ride it

the paint will have still been soft and mud will easily stick to it

darn So I should rub the area down a little (so it has something to grab) spray it with some more paint, then leave her to tick over for a while? I had left the exhaust drying in the garage for about 5/6 days, then bolted it back on yesterday, and then ridden her today, for about 3 hours straight... but that's obviously not worked... unless the mud got on there at the begining and got baked on... How long should I leave her running? Bearing in mind she's a 50cc single cylinder, water cooled, 2 stroke.

Many thanks.

BBQ paint from b&q, goes on nice dries well and looks factory. Thats what I used

As mentioned once sprayed you need to bake it, but you need to layer it, bake layer bake etc.. Also the paint has to withstand 6000 degree heat & the B&Q barbecue spray is only 1200 iirc.

You could try a fine sand bake it say 20 mins maybe then spray then bake sand spray bake etc etc.

Good luck. It will rust through within weeks so, dave your pennies& spend it on fuel...

Thankyou for the advice. I'll see about spraying it again in the comming week. I'll have to use the trials bike for a while, but even on that's exhaust, the paint is comming off the base where it joins the cylinder head. Stainless is the way forward, but there all aftermarkets and sound terrible

I'll try the layer bake method, but I'll have to leave it attached to the bike while spraying, as trying to bolt the thing back on takes about 40 mins, due to inaccessable head bolts. But even if I do this, i've got the problem that there is a metal bracket (welded onto the the exhust) to support it when in positin. This wont get all that hot, so even that will still have the same problem.

Thanks again, i'll post back once i've had another shot at it. And you may even get a pic to show what i'm on about.
