hi, i visited my local spayer and he quoted me £200 for a full spray job aslong as i do the prep. i have started by removing the bonnet and boot and prep them off the car. i have done all my sanding and done a few coats of primer from a spray can.

is spray can primer suitable for priming the car? if yes, what is the best brand and if not what primer should i use? i can get hold of a compressor and a spray gun.

thanks all!!

we use aerosol primer at work (bodyshop) on small areas but for priming a whole car best bet is 2k primer and a spray gun. well thats what ive been taught.

hey, thanks for the quick reply. could you point me in the right direction for good value primer. also have you got any tips for the grit of paper to use etc..?

thanks again

well im not 100% on this as im still an aprentice, but at work we use upol highbuild primer, not sure on the price but it does the job. and in regard to sandpaper, i think wet flatting with p320 is a good enough finish for paint but im sure you can find a better guide to flatting paper on here in the bodywork section as like i said im still learning and im sure theres lots of people on here who know the subject better.

thanks again the info is great. i know you stated that you are an apprentice but do you know how much primer would i roughly need?

[Alex_B]

i honestly dont know how many cans you would need but to be on the safe side probs about a litre of high build primer and half a litre of etch primer, ( that is a safe guess so if anyone has a better idea feel free to share )

sorry for not stating, but i was asking about if i used a compressor lol. thanks.

yarr if using a spray gun probs about a litre of high build anf half a ltr of etch, thats airing on the side of caution

Hi mate. We've just sprayed our mini but prepped it with spray can primer. Will check the make of it when I get in because it's really good to use and has a very good spray radius and finish, didn't even have to flat it back after. We used about 12 cans in the end at 2 quid a can because Iv got a trade card, forget paying a tenner a can. We used 400 grade wet/dry to key the paint before spraying it on too. Hope this helps

acid etch prime the baremetal areas, then ideally spray the rest with 2k primer, them flat with 400 grit, thats what i done when i painted the front of my mini

hi thanks for the replies. benh, how have the spray job turned out and did you use celluose or 2pak top coat? also is acid etch primer the same as etch primer?

thanks again all

etch primer is acid etch, lol. 2k is tonnes better than cellulose.

cellulose is air drying, so the chances of reactions, etc due to humidity levels or temperature, etc is far greater.

2k is a chemical reaction, so the paint doesnt dry, it hardens, and theres less chance of reactions due to atmospheric conditions

would a professional sprayer use 2pak or cellulose?

[samsfern]

most would use 2k, although 2k is seriously dodgy stuff that you dont want to be breathing in, so if you do spray it, make sure you have all the right respiration gear!

im getting it sprayed by my local sprayer. would 2k need different primer from cellulose, vice versa?
