Home spraying - The rattle can paint job - How is best?

[perry]

I did my trailstar with dulux gloss . People only really notice when I point it out , a liter only cost about £8 and I've only used a very small amount on both frame and forks . I didn't bother with primer and it's been fine for a year of neglect . I removed the original paint on the forks in the morning , painted a few coats during the day and was riding on them at the pines in the evening

If I get a scratch I just chip the mud off the area and slap some more on with a brush .

No point spending real money on nice paint for a bike I wont be cleaning

Oh your right, they *can* look nice, but by the time you get them there, the materials and time costs make Bob Jacksons seem like a good option, especially since despite using various etching primers, multiple layers of paint, then layers of clear coat, it still flakes like a sun burned albino.

i beg to differ

all the items you see in the pics i painted with a rattle can in the garage,
all it takes is time,

n they have all proven them selfs the cam covers have been painted for well over a year n still look as fresh

Correct me if I am wrong, (despite being an Engineer by trade I will never confess to knowing much about engines!) But the painted surfaces on the samples you have shown are not likely to suffer much in the way of scratches or impacts?

It its when you get any sort of surface damage that the paint starts to fall off.

That said I am sure it is not always the case and it is possible to get a good durable finish...I just have not seen one on a bike.

Speaking from experience and a fellow engineer , the paint on a cam cover needs to be pretty tough too. The extremes in temperature, oil/water/other contaminants and plenty of high frequency vibrations all contribute to peeling paint. I've had a few mis-painted engines that only lasted a few months through trail and error

Done a few car parts with rattle cans.. spoilers, wing mirrors, interior bits and bobs. .

Good quality paint and good (no.. excellent) prep can make for a good result.. get a clearcoat that's hard as nails and it should be durable too (don't know if such a thing exists, I've only ever painted Vauxhall car parts using Vauxhall rattle cans)..

a super hard clear coat is prone to cracking on a flexy steel frame, but agree preparation and patience is the key

Logical. . . which is 100% why I didn't think of that. .

You can't see to well from these pics but i painted this with rattle can, the finish is like glass

But it took hours to prep the frame n i mean hours, so much so that i actully fear riding it just incase although the finish has proved tough!!

and because i have used a base colour touch up will be easy
