Firstly the preparation must be done right as to the rub down and any repair it pays to get good advice at all stages and next is to decide what type of paint and color you are going to do the car etc with like enamel/acrylic etc ok now the rule of thumb... (a) look at the job and find out the code on the manufactures plate, if the car has change of original paint code find out if enamel or acrylic, this will help you for some paints if within 3 to 5 yrs can cause certain reactions to other paints being applied over if not sealed or isolated etc. (b) Clean down area wash the area and start the first repair, only with water no detergents and let dry completely, always take repair area's back to clean metal and ruffian in this area to help adhesion of filler and only apply fillers lightly, coat each layer over after rub down to reform body shape, before you fill the damaged repair area you should if needed apply a rust inhibitor on the bare metal area, as to fillers you can start with a metal mend type and finish if with liter bogs etc but it pay;s to panel beet out the area as much as possible so not to have to much filler in the repair area etc, other wise future possible cracking. (c) Sanding down first stage, depending on paint condition good paint surface 600/800 wet/dry paper with ever water or dry rub but wipe as you go and watch all edges and rub out all possible chips bad scratches and take shine away right to edge unless doing spot repair, always use round motion/ not straight (d) Wipe down well, now mask of all area's not to be sprayed always use clean cloths lint free and now wipe surface down with wax and grease remover and make sure you wipe all areas and not much on filled area's as this can soak up the solution and problems later on, turn cloth regally and change cloth and do not touch it with other hand best done in cool area to save solution drying out to fast leaving streaks etc. (e) Now have a good look at the surface and have car in a good lighted area inside a shed etc and make sure that you have read the manufactures full instructions as to the first stage as to Priming the job and now look at the spray unit. (f) Spray unit the most important thing in this job as with the painting etc, see that the tank is big enough to provide as much air as you will need to spray in large direct spraying or you will have to wait for it to catch up when you are spraying and make sure it has a water regulator trap and bleed on line, firstly clean out the regulator trap for any water within and filter or replace filter, check compressor for oil in motor is at mark, have the unit is a safe place and any air flow from the unit away from the spraying area, as particle's from the compressor will mix with your paint, (e) The gun make sure it is high pressure gun with fine nozzle and the finer the better, you can change the settings and the air volume and flow to suite the type of paint etc. (f) Make sure that the area is fully free of dust and anything in you way that you have a full face mask as to the regulations only the best mask will do, and make sure there is nothing in this spraying area that can cause and spark or flame etc keep it safe always and there is a saying there is only one of you and you can not be replaced and as with your lungs they keep you going and don't be a fool like so many others etc. get a test piece and now read the thinning instructions as to the paint for first application, have mixing containers not plastic one's, a measuring pot marked so you can mix your primer and top coats, NOW LETS GO BACK to the GUN and the compressor, turn it on and let the unit run to full pressure that it shuts down and then undo the drain until it restarts again, do this 2 times lets condensation out of tank now turn regulator valve air bleed open to release water in trap, now connect line to trap, now put a little thinners in pot and spray away from any area of job and away from all sparking and flame, CONNECT GUN to hose and turn the air adjusting pressure to the manufactures setting as to the paint you are going to spray and to set the right pressure it pays to hold trigger open while adjusting so you have no line air change to the gun for the length of the hose can change the pressure to the gun, Now you have the gun set and sprayed a little thinners, empty out the rest and fill the pot, make sure you have mixed your paint well and thinned it correctly, Go back to the trap and release any water etc, NOW YOU ARE READY to test your spraying technique and adjust the air flow and the flow of the paint and set the right fan type you need, IMPORTANT NOTE when spraying any paint it is very necessary that the air temperature is right and this has a serious outcome on final application and look of the job/ NOW when you test your spraying style hold your gun far enough away so that you do not get the job to wet or to dry start out off the edge of the job hold gun always straight at the job as you pass in a smooth even flow action and this will take practice to get it right, finish outside the job area and at all times fully depress the trigger of the gun, you have make some adjustment's a get the feel of the gun and your actions never be in a hurry to rush yourself and do not keep applying coats and allow to dry between coats, NOW YOU are ready to start your job so let recheck all things and now start outside of the job area and at the set distance you are happy with smooth passes place a light coat over you job and work around your area let air flush off and reply second coat over lapping between your actions, you can apply 3 coats depending on the surface etc and let it dry fully, After it has fully dried you now can recheck job and now wet or dry sand with 600 / 800 clean down with wax/grease remover and now you can apply spray putty coats with putty gun if needed to hide scratches, apply light coats allow to dry fully between coats and do not apply to thick, let fully dry and sand with worn out 600/800 wet/dry paper/ only dry sand and again wipe down now respray primer until it is fully covered to job leave to full dry depending on air temp. NOW rub down the job with now 800 with a little water not to hard just work it easy and wipe down and check surface if need re-coat only area's needed and lightly rub the same, leave to dry fully. BEST method for top coat, FULLY CLEAN THE GUN DRAIN AIR TANK and REGULATOR of any water and check the air temp VERY IMPORTANT, to cold no good to hot the same AROUND 19C to 26C is reasonably good, make sure job is fully clean and dry and now mix your top coad adjust the air flow pressure and fill the pot of the gun test your piece as a test spray as above, set the FAN AND FLOW AND AIR RATE UNTIL YOU ARE HAPPY WITH IT, MAKE SURE THAT THE FAN RATE AND FLOW IS CLEAN AND OVERS IN A CROSS STROKE ON YOU TEST PIECE , now you are ready to apply first tack coat, START OUTSIDE OF YOUR JOB and depress the trigger fully and on large area's such as hood it pays to start from center edge overlapping each stroke and finishing outside of the edge of job, FIRST COAT IS TACK COAT AND IS A LIGHT COAT, NOW APPLY SECOND COAT and cross at opposite direction overlapping and apply at a slower action NOT TO SLOW this will be a wet coat LET TACK OFF AND recheck job NOW APPLY IF NEEDED ANOTHER WET COAT BUT NOT TO WET, let tack off , NOW THIN THE PAINT TO A GREATER AMOUNT AS TO THE DIRECTIONS AND ADJUST AIR FLOW TO A NEW SETTING OF RECOMMENDATION AS TO INSTRUCTION now moving the gun at a faster rate and smooth action apply the final coats being careful at this final stage and not over doing it, YOU WILL ALL SO HOLD YOU GUN AWAY LITTLE FURTHER AS WHEN YOU FIRST STARTED, YOU WILL ALL SO SEE THAT THE TOP COAT IS SHINNING MORE NOW AND YOU CAN LET IT DRY FULL FOR A FEW DAY'S OR YOU CAN APPLY A CLEAR COAT OVER MOST PAINTS THESE DAY'S, BUT THIS SHOULD BE DONE A LEAST 20 minutes or so after you have the top coat on so that the 2 applications form together, FINALLY, some spray painters rub between each and every coat if there is MODAL OR ORANGE PEEL AND THIS CAN COME FROM MANY FACTORS, it is a leaning curve and technique, so be patient and practice remember safety all the time. AFTER IT HAS FULL DRIED YOU CAN RUB DOWN IF YOU HAVE PROBLEMS LIKE ORANGE PEEL OR SLIGHT RUNS ONLY WITH ACRYLIC PAINTS AS WITH RUNS ETC ENAMELS ARE ABIT DIFFERENT AND YOU WILL NEED MORE ADVICE ETC, THE FINAL RUB DOWN WOULD BE WITH 1000 TO 1200 0R HIGHER WITH PLENTY OF WATER BUT NOT TO WET, AFTER THAT YOU CAN BUFF OFF WITH A GOOD CUTTING COMPOUND WITH BUFFING MACHINE AND LAMBS WOOL PAD CHANGING IT REGULAR AND YOU MUST WATCH THE EDGES OF YOU JOB AFTER THIS YOU MAY WASH YOUR CAR BUT NOT WITH A HARSH DETERGENT AND WIPE IT DOWN CAREFULLY, AFTER SOMETIME WHEN THE PAINT HAS FULLY HARDEN YOU CAN APPLY TEFLON CLEAR OVER IT WITH UV PROTECTION IN IT ONLY USE THE BEST BRANDS NOT THE CHEAP ONES BEST OF LUCK Pedro the Painter [Report message to a moderator]
