How can you get a good paint job with rattle cans

painting aint that hard with the right equipment (ie not rattle cans)

i got a Iwata HVLP spraygun for about 100 off ebay, once it was dialled in you can get near-perfect finish straigh out of the gun. this was my bumper the day after i did it, 1k paint and upol 1k laquer (didnt wanna give myself isocyanide poisoning), sprayed in my garage with a crappy little compressor:



thats straight from gun, no flatting or polishing whatsoever. I figured that the gun will last me a lifetime of touchups so will easily get that back if i never have to go to a bodyshop again.

one of my mates has blagged a airfed mask off his nect door neighbour (who works for devillbiss) so we're gonna completely respray both our cars in the summer, will be doing a full how to with loads of pics!

 

nice which kit did you get Matt?

 

you know someone who works for devilbiss? How much can you blag another air fed mask for, possibly a Gti pro or two?

iwata make great guns, quite popular in america. I had an iwata w400 for a while and it was great.

1k stuff is stilll poisonous, just kills you with other chemicals

 

what sort of finish would you get from a little 20l tank compressor?

 

a spray gun would probably drain the tank in no time at all so you wouldnt be able to use the gun for very long.

 

i got an iwata LPH-50 gun, really nicely made, makes you realise how crap those 25 screwfix sprayguns really are. RRP on that gun in the UK is near the 300 mark, i took a chance and imported one from the far east, its defo the real deal though. Its only a little gun tho, ideal for touchups and single panels but wouldnt wanna do a roof or bonnet with it.

my mate bought one the same, and has subsequently bought a LPH-100 which is a full size HVLP gun, and is essentially spraygun porn , thats what we're gonna use for the resprays. he had to beg and beg to get the airfed mask off his neighbour so doubt theres any more where that came from, he couldnt get me one and im his best mate! haha

my compressor is a tiny little 1.5hp thing with no tank at all, it just about manages to keep enough pressure with the gun fully open. seems to spray fine with it though. when we do the whole cars were gonan get a pair of 50 litre 3hp compressors, one for the gun one for the mask, and go halves on everything to keep the costs down.

 

painted with cans , 14 500ml to be precise , with sanding e.t.c. but not high gloss this is semi-gloss, full matt paint tended to go shiny in places, not a show and shine car.









this was done by a company and after a month i sanded it off as the orange peel was really poor then came the spray cans!!

 

Decent finish with rattle cans?

I need to paint some small items (mirrors and rear spoiler).

They are currently bright yellow and I want them black.

Is it relatively easy to get a decent finish with rattle cans?

Or should I just pop along to the sprayers?

 

easy enough. If they are contrasting items (ie not going against black paintwork etc) then you can get a good finish. You going gloss black/laquer?

 

easy peasy!

from this



to this, i resprayed virtually the whole back end



juts spray in the normal way, the after the final coat get some 1500 grid wet and dry and rub down (wet) the paint will now look dull, grab yourself some cutting compund such as g10 apply that then some polish and wax and loads of elbow grease!

iam not an expert and tbh iam not the best at spraying but mines come out okay

hope this helps

 

Its for my brothers car, which is white, so yeah contrasting items.

Gonna do them in gloss black.

So sanding them down, priming is easy enough, but how do i ensure a good finish with gloss from rattle cans, whenever I've done it in the past, it always seems to have blobs of paint and runs on it, am I spraying too thick?

 

copeidge - that looks great.

So just spray, flatten back using 1500 grit and then buff up using polishing compound?

I have loads of compound and a Porter Cable so that should be easy enough!

 

yep. You get the shine from the laquer. When spraying, it is 'dull' when the paint is thin but looks shiney and a good finish when its really thick so its tempting to spray too much. Just build up lots of thin coats, then go mad with laquer and it will shine like a goodun.

I did my wheels with halfords own gloss black and laquer and pretty happy

 

if your getting runs then probablty a bit thick coats, hold the can farily far away and just give it a dust over (doesnt matter if you dont cover everything in one pass) let it dry and just more thin coats until you have a solid colour, then rub back after 24 hours drying with 1500grid (wet) sometimes you dont need compund but it saves on elbow grease if you have a machine polisher, dare i say even t-cut then polish then wax and it sould be good,

cheers!

 

yep as above! another technique is to rub back the final colour coat as i said above the wipe the panel with pre paint and get rid of dust and crap the coats of laquer.

 

btw are those attachment sprayer for the cans any good? i though about getting one.

 

^^ im not sure really. I want to try it on plastikote cans which is what they are designed for. Didnt work that well on halfords one as the fit wasn't great and caused a paint build up on the rim which if left then caused big splodges of paint to flick on what your painting!!!!

enables you to moderate how much paint comes out which is handy for bits were you would normally gets runs/build up etc. Im buying a compressor and gun soon

 

Guys, both of you have been VERY helpful.

Thanks a lot, I feel a lot happier about attempting it now!

 

pics when done so we can laugh at your attempts dave
