Hi all just read through a few threads and they throw up a few queries im ready for my last coat of base colour tomorow and have the lacquer ready too was wandering what to key it back with im thinking a fine grey scothbrite to take the shine off before lacquering.

I have also read that some people say not to take the shine off and spray the lacquer straight on top while its still tacky just wandering how long it takes for it to get tacky .

many thanks lee

ideally you want to put your base down then the laquer straight on as it will bond better when its gone tacky. its called wet on wet and works with most paints now adays. if you do run out of time and you hve to let the base dry dnt fear as you can leave it for up to 24 before applying laquer but no more as give it few years and youll see why.lol
if this is the case and the base does dry.. yes use grey fine scotch pads to key it back and nib out any dust with sum 1200 wet and dry but only nib out not flat....

Apply your clearcoat as soon as your basecoat has dried, dont risk it not adhering by doing it the next day.

Basecoat can be nibbed to remove dust but you need to apply a fresh coat of basecoat over the area you nib before laquer or it will show.

Im not sure why your basecoat is shining as it is a matt or satin looking product. You may be applying it too heavy, the idea of basecoat is more even coverage, not a finish, that is what your clearcoat is for.

Hey Lee,
how come you did not lay the base coats all at the same time? (allowing for flash off times) Did you run out?!!
I'm assuming that it's 2k and not water based? I normally lay the laquer (if 2k basecoat used) around 30mins after the last basecoat. But that is only on the product I use. You could very lightly run over with a gold scotch (3m) which are really fine before you carry on laying down the basecoat.
The best answer though is to ask the supplier for the paint manufacturers spec on that product.
It's taken me years to learn to paint and it's not as easy as it looks! Good luck to you and don't be disheartened your'll get there in the end and be proud that you've done it yourself!

Thanks for the replies im going to have to let the final coat of base dry now as i have a run to sort out this is my first attempt at a full respray and i have learnt a great deal i will be using the grey scotch bright to key it back i presume it has to take the shine off again i will sort out the run as best as i can but im pretty happy with the rest of it . I think perhaps i did put it on thick as the thinner i tried to apply it just didnt cover and didnt really look right you learn from your mistakes !! the only worry i have now is keying it back will obviously create small scrathes to key it will these show through the lacquer

thanks again youve been very helpful and i will post pictures up very soon

ive just had a thought ive got enough paint for another coat im might nib out the run then apply another base coat let it flash off (30 mins) then apply the lacquer

good tip for showing of imperfectitons of flatting.. if you flat or nib something out. spray it with water ull see that most nibs dissapear unless your doing a dark colour, lighter colours you can apply laquer with no worries of it showing through, if you cnt see it throught the ater u wont see in throught the laquer.
what type of paint are you spaying for the colour anyways carcraft said about 2k?? if your spraying 2k colour theres no need to laquer it if its base it will be either synthetic or acrylic not which are all 1k. if its 2k it will be shiny when you it dries if its proper "base" it will dry matt like jack_marshall stated above.
