Re: 1973 starcraft ss restore in progress
ya plenty of snow here! gonna be around awhile also as they are talking 25 below for a week coming. i did get a coat of rustoleum rusty metal primer on using the hvlp sprayer from HF. went pretty well, took awhile to figure it out and used more paint than should have probably by the time i got it right. used a full quart for all of trailer, but pretty hapy with coverage and looks real smooth. my procedure,was as follows. i air hosed it down, then sprayed it down with acetone using hvlp gun. dries very fast, so took a 1/2 hr to mix 16 ounces paint to 4 ounces acetone to thin it. ( this seemed like about right and sprayed well) stirring slowely whole time. sprayed all i could on trailer and then smaller parts, axel, and fenders. waited a day and had wife and daughter help flip trailer and then did the other 1/2 or so. real happy with how it turned out, and lessons learned with gun. it was real easy to use and adjust as needed i felt. a couple things i would do different is wear a light mask, as nose hairs filled up, annd practice a bit more so i did not waste so much paint in learning process. will post some pics tomorrow of it with primer on it.
now question time, looking for some advice. remember it is a trailer, so my thoughts are air hose off, spray acetone cleaner, spray 1st coat of topcoat.
question 1 - is 1 coat of primer followed by 2 coats topcoat sufficent?
question 2 - should i use hardener in both topcoat applications or just last one?
question 3 - really dont feel the need to sand or smooth out between primer and top coat or each top coat , its a trailer and really pretty smooth now after primer , thoughts or suggestions?
question 4 - how long between coats to cure? i waited 16 hrs to flip it and did not scratch or lose any primer, dried very fast, and some theories are to cover next coat before fully cured. ( have heard it helps one coat adhere to other ) or wait longer before each coat. thinking a coat a day would be my preference, using the rusto professional, keep in mind i gotta flip it for full coverage, so a total of 1 coat primer and 2 coats topcoat is actually 6 sprays for me.
thanks in advance, and any thoughts or advice is appreciatted.
