Re: single stage paint questions
If u are going single pot u have enamel or laquar, I dont think the old nitocellelose is avalable any more unless u buy lots of nail polish.
These paints dry rather than cure, which have there own quirks also
Any undercaoats, espec the last coats for fimal block down, should be left for a good week before blocking...this gives them a good chance to shink 1st
Enamel is not very forgiving, it runs/hangs easy and not suitable to sand out, means wiping off panel and respray....
1st coat thick enough to just see thru, 2nd coat goes on when u touch with the finger and it stretches, this holds the sec coat up...u then get the hell out, and leave for 12 hrs
It is slow dry and if mixed and put on correct at the right temps will flow out over night.
Enamels, if cut will loose a little of the orginal gloss, but still looks good.
After a month or so polish, and maintian a good polish as they do over period tend to chalk off.
Laquar is very forgivng, fast drying, nice finish but lot of finish work.
Again let undercoats dry like enamels, and final block down
1st coat again so can only just see thru, by the time u have finished the 1st dump, where u started will be dry to touch....hit in with a quite heavy coat, but dont go overboard, u have to be real agressive to get it to hang or run..Then hit with a ouple good coats of clear.
let dry for a week then light wet sand with 1200, and again heavier with 1600.
Then cut.. polish about a month later.
All systems should use the right type of undercoats and thinners, not doing so can end up with alsorts of issues from frying, paint cracking after couple summers, to paint going glug in the pot.
