painting

[renagades]

How do you prepare a welded area on a fuel tank for paint, as obviously after it's been welded it's sort of bubbly metal,

I didn't want to grind it as i was unsure of weather this would create leaks or damage the weld?

Renegades - mate.

Do you know anything about restoring a bike? I don't. But then I didn't buy one to restore. This has to be the 10th post about some sort of mechanical mishap or advice to do with this CG.

I'm sure people are happy to help - but they might be more inclined to do so if you would contribute more than just posts about how to restore this thing.

Sorry this is a bit off topic, but I thought it should be said.

got to disagree with you their rookie, you dont buy a bike to restore after you've learnt how to restore it you buy a cheap bike to learn on, I done exactly the same thing with my opel manta. Most I done before that was change a distributor cap but on that car by myself I learnt to weld a new floor, roof and sills on that, prep and spray it with the compressor and fit a 2l seh engine from a cavalier in their. My cx I bought was my first bike (never touched a bike before it) I had to strip down to bare metal fit the engine work out how to wire most of it in once you've done it once the hard way (you learn lots more doing it the hard way) it's easy after that.

you grind the weld so it's clean (and smooth if you like) then you use upol filler over it to blend it in, sand it down then wet sand with 1000 (maybe 1500 if it's in a place your going to see a lot and need it perfect) and prep, primer spray.

Their's stuff you can buy that you spray on before you weld which waterproofs it and allows you to weld over it (bit late telling you that now though). Just remember primer isn't waterproof so if it's in contact with moisture/rain get it done sharpish or you'll be redoing the welds.

if the welds are good on it btw griding wont be a problem, I welded up my own exhaust system and had to make a reducer, I cut the length of one section of the pipe folded it then rewelded and grinded it flush again, even before slapping on some heat paint you couldnt tell it had been welded and was still very strong. How strong it is all depends on what welde your using and how your welding it though (what gas you using on it?) if it's pub gas it won't be all that strong. I've welded with pub gas its tricky but not sure i'd trust it to be airtight after grinding.

Thankyou kindly for that reply.

Everone knows you have to start somewhere, usually by throing yourself in at the deep end.
Put people who are already at the top or just strange people all together like to interfere.
The way i see it is , if you want to post something helpful then post. If you don't agree with what i'm doing then don't read about it and getyour self more worked up.

i've wet sanded lots of filler (and I mean lots) never had a problem. How do you think you fix slight imperfections in body panels before spraying. obviously you dont leave it wet or it'll soak through and lift you dry it once your done. No primer is classed as waterproof, even paint isn't fully waterproof to get technical. I personally wouldnt leave primer as my only guard against water on bare metal.

agree to disagree then by the sounds of it, although I have no idea how you yourself prep a car if your not prepare to wet sand it. My way works for me your way works for you. one thing I can tell you whatever car your prepping for spray it will need filler to remove imperfections that the paint will bring out. I've not seen one car that hasnt had filler wet sanded before spraying new and old cars.

lol stop quoting everything i say its very annoying and very sarky i'm giving this person advice from personal experience. sound like your the type of person that believes your always right and theirs only one way to do a job. If you do this stuff for a living your bound to know more than me, I simply say what i've done and what's worked. Hands on experience.

How on earth would you tackle imperfections like this then if your not prepared to wet sand filler:

you could dry sand that i'm sure then wet sand the primer but that's just silly if you ask me, what happens if you dont get it quite perfect your stuffed then if you wont wet sand filler and you've already primered it.

unlike you i'm more than willing to learn from people and take advice so enlighten me please. Their's always more than one way to skin a cat. I don't know where all this sarkiness is coming from what happened to good ole discussions.
