Spray gun

Post by **katiekat** » Mon Jul 06, 2009 6:34 pm

Hi there!

Can anyone recommend a good gravity feed spray gun? I find mine fiddly to control and it seems to get clogged easily.

Maybe it's just me though!

Thanks for any advice.

does it have to be gravity fed?

i prefer the one with the pot underneath.. I can find the make out if you want.

I like the gravity fed guns as I find them better for horizontal surfaces and you can use just a little paint in them if you need to.

I've got a Sealey S701G at the moment.

I use a DeVillbis Gti but thats serious wedge new.

Have got an old underslung Draper gun thats quite forgiving but it really depends on your compresser as some guns use massive amounts more air than others. As you say it also leaves a little more paint in the pot when finished.

Our old spare DeVillbis gun uses twice the air of the newer one so can't really do many big panels as the compressor can't keep up with it.

I'd love a DeVilbiss but they are so expensive!

Worth keeping your eye out I picked up our spare for £50 (with a Die grinder and an orbital sander) at a garage sale.

Bargins are out there but you just need to be lucky.

Yes you're right thanks Paul!

If it keeps clogging - you are needing to filter the paint as it goes into the gun pot. Changing to gravity won't help if there are 'bits' in the paint!

what are you spraying,celly/2K ? are you thinning it, how old is the paint, what needle size has the gun, how long are you leaving it mixed or in the pot,do you strip the gun fully everytime you spray, what CFM are you using have you a water/oil trap in the airline or a regulator and are you filtering the mix, does the gun have its own filter.

Kate - you just missed a DeVillbis Gt on Ebay for £79! Seem to be a few of them advertised

Good luck with Jonathon's questions

There's plenty more

I feel it may well be the sealey gun itself as they are not good quality. The GTi gun is and at £79 is a bargain, so long as it has been treated well.

It hasn't thrown up anything very useful this time but worth trying for almost anything.

Well I've had a bit of good luck. My daughter's driving instructor has offered to help me finish the Midget. Well why is that good I hear you ask?

He was a professional paint sprayer for 21 years so I'm hoping to learn a bit from him. I just found out that I'd mixed the base coat wrong, I wasn't supposed to add any hardener! Oops! The hardener was meant just for the lacquer. It says on the tin mix 2:1 with hardener. I was using 10% thinners.

Thanks for all your great advice!

strange for basecoat as its normally 1-1,the laquer is 2-1-10%.

Post by **katiekat** » Wed Jul 08, 2009 8:18 pm

I think I'll check with the paint shop!

ask them if the basecoat should have had polyester thinners and not standard thinners. Using stanard could cause issues when you put te clearcoat on (blistering or solvent pop)
Also check the laquer mix some are 2-1-10%, others are 4-1-10%, do not thin the final coat as you would with celly, good luck, hope you are painting this one with the relevant conditions, and not on the drive !
