Posted December 8, 200717 yr Are there any spray painters, either you do it as your job or are a good DIY'er - I need some tips. Never used a gun myself but have given myself the daunting task of spraying a car - tried out the bonnet today but it's not turned out as I hoped!
December 8, 200717 yr There's a guy selling DVD's on ebay on how to paint cars... some of the clips are on youtube actually.. just have a search around, it's not as simple as you think!
December 8, 200717 yr i am not brilliant at it but i can spray and really the spraying is the easiest part of the process its the prep work that needs the most work because of it ain't prepped correctly then it'll look sh*t no matter how good your spraying is.have you got a pic of the bonnet you sprayed or could you tell us about what went wrong someone may be able to give you some pointers as to where you went wrong buddy and how to rectify it
December 8, 200717 yr Author Thanks stoo, but it was really an appeal for anyone so then I could ask them some questions via PM. Anyway the paint I'm using I mixed 50/50 with High Gloss thinners as per instructions - but the bonnet turned out "flat" looking, no glossy effect. It was also quite rough to touch, I used a bit of wet and dry and it seemed to take off the roughness. The preparation side I used 800 grit wet/dry over the current paint, then I used panel wipe to degrease the panels using a cloth. The thing that gets me is I tested a small area out on the car and it seems to have dried glossy so I can't figure where I've been going wrong. The only thing that sprang to mind was perhaps dust being picked up easier as the bonnet was sitting on a bench, as vertical as I could get it but with dust sheets to cover the floor.
December 8, 200717 yr 800 grit is a bit severe to be using prior to top coat, i usually use 1200-1500 grit to key the bodywork as anything less tends to leave marks under the top coat... what kinda spray gun you using? do you have any heaters etc around when your spraying? and what grit paper did you use then to flatten down the rough paintwork as if it was the 800 that is waaaaay to severe?
December 8, 200717 yr Sounds like you might of been spraying in too cold conditions which is why the paint has gone flat
December 9, 200717 yr Author radient red by any chance ? Orange... I've got a small space heater but I actually turned it off when I was spraying, didn't fancy the air blowing across the spray. Maybe that is the main reason. I also did it near the garage door which could well have been the coldest part of the garage. Just don't want to set out and paint the whole car for it to end up the same.
December 9, 200717 yr The preparation side I used 800 grit wet/dry over the current paint, then I used panel wipe to degrease the panels using a cloth. thats to rough my friend 1000 wet and dry and the paint needs to bite plus the cold air doesnt help anymore questions PM me
December 9, 200717 yr Author I've got some 1200 wet and dry paper so I will smooth off the paint with that then try painting (with the heater on!) and see what result I get. Thanks everyone for your tips.
December 9, 200717 yr post pics and how you've done it step by step and people will be able to point out where/if your going wrong. as well as give tips
December 9, 200717 yr Ideally you need to be working in conditions of sround 21 degrees really, the car shouldn't be cold to the touch either. base coat should be mixed 1:1 with anti bloom thinners (better for diy and if conditions aren't ideal)and the top coat of lacquer or clear coat must also be mixed 1:1 with the thinners. You need the lacquer for the glossy finish. firstly it sounds to me that you haven't got enough paint down on the car which is giving it that rough texture, you can give a couple of thin dry coats and build up colour, that way or when a bit more confident using the gun etc get the paint on in less coats which will mean less flatting and a better smoother finish. Assuming all prep work is of a good standard, the undercoat original paint or primer,prior to the base coat needs to be flatted back with a fine grade wet n dry paper, then you need to spray the base coat ( the colour)don't worry about runs etc as this again needs to be flatted back with a 1600 grit or even finer wet n dry. the top coat (lacquer) should then be applied in much the same way as the prior coats and if your good when it's dry you shouldn't need to flat back and polish but if you do then use the finest grade paper your can find and flat back any blemishes with this before using a polishing compound job done!
