polyurethane interior
Sunday, October 09, 2005 3:17 PM
Ok, i tried a search but i didnt get any results...maybe i spelled it wrong. But i am currently sanding my interior and i like the glassy look, but i like some of the "stock" but custom look you guys have so i was thinking...

can you buy the clear polyurethane stuff like what you buy at lowes and put a coat of it on your vinyl and plastic interior peices then paint over it or put the poly. coat over the paint?

My overall question is..would this give that glassy look? with or with out the "stock" texture look? i think since it dries hard and clear it would work...


...are you trolls that dumb that you cant realize mid 15s is slower then 14s?

Don't do it. It will eventually start to yellow and it will look like a dog pissed all over your interior. Even the good stuff that says it goes on clear and doesn't yellow will still yellow to an extent and will be noticible. Another problem you will run into is heat. If you have your car sitting out in the sun for too long beaming down on your interior you might get heat marks or ripples in the polyurethane coating. I used it on a speaker box that I painted yellow to math my car and when it was finished it looked great, but I left it out on the porch one day in the summer before I even put it in my car and the sun heated spots into it. Granted I put a crap load of coats on it because I really wanted a high gloss as I could get on it. It was smooth when I finished it and let it dry for several days at a time for each coat. When the sun beamed down on it it got very slight ripple marks in some areas. Almost as if you put a magnifying glass and heated one spot the whole time. I got pissed because of how long it took to finish that box that I scrapped it. No way I was gonna sand it down and do it again. The finish was perfect, smooth and a shiney as a grand piano, and bam... wave like ripples... I wouldn't recomend doing the interior with it unless you plan on only driving at night, lol.

hmmm...that kinda sucks...cuz i figured it would be a good way to get that shiny look. would it do the same even if you painted over the poly coating? or can you do that?

ok there is a couple of ways you can go about this and they all depend on time and money and how well you want the end product to look. you can do the urithane idea if you put about 4 heavy coats right over your interior let it dry ompletly then get lik 200 grit sandpaper and sand it smooth then go with a higher grit like around the 700 grit level sand it again till its flawless (any thing you can feel you will see it dont use your eyes when doin this use your fingers to feel any defects.) spray with a sandable primer then sand the primer till its flawless with the 700 grit paper then spray your actual color when that is dry and you got a few good coats sand it again with the 700 grit then lay your clear on top of the color and sand again with high high grit like 1000.
a better looking way is a bit more money and alot more time but in the end it looks better. fiberglass it a good glass for this is BONDOGLASS its like bondo but its fiberglass now this route takes hours upon hours to do i have 46hours per front door on my cavi and im still not done i still have the dash and rear panels to finsish but i promise you the end result is amazing.

goodluck

or you could just sand the plastic smooth and prime it with a high build primer, wet sand with 400 grit then paint it whatever color u want with automotive paint.

^^ yea sanding takes forever...i figured since the poly dries think and hard it wouldnt have to be sanded...im testing it out now but since it takes a while to dry i was only able to put one good coat....ill let you guys know

i couldnt find any polyurethane that wasnt for wood...so im trying the wood stuff...im using small/ easy to replace peices so dont worry

if your using a brush to put the urethayne on its not going to be smooth, it may look good but once its painted youlle find all sorts of high and low spots that will show up when its shiny. youlle still have allot of sanding with urethayne, problaby just as much since it will harder to tell when everything is perfectly smooth.
