kramttocs Posted May 25, 2022 Share Posted May 25, 2022 Bringing this one back up as I am looking to paint a couple faded plastic pieces (maybe all of them except the dash if they come out good). I spoke with SEM and was given these steps: 1. 39362 Sem Soap - grey scuff pad give it a good scruff then rinse off. Dry. Removes water based stuff 2. 38353 Plastic and leather prep. Spray on a wipe off in one direction with dry cloth. Removes solvent 3. Test with acetone on back. If melts then use promoter 38363. a. Spray and while wet apply a coat of color b. Apply color so it's wet c. As soon as it's dry (5 min), do another coat d. 2-3 coats is all that's needed (NO?) 4. If nothing happens to the plastic with acetone test then use 77723 a. Spray a wet coat but let it sit 5 minutes to flash b. Then apply color so it's wet c. As soon as it's dry (5 min), do another coat d. 2-3 coats is all that's needed (NO?) The (NO?) is in there because I called a shop that mixes SEM aerosol and they say 5-6 light coats which is much different than 2-3 wet coats. ? Big question is that I've seen mention of both promoters (77723 and 38363) on this forum. Has anyone done the acetone test and confirmed which one is needed for the trim plastics (doors, pillars, etc)? Scott, I painted my trucks entire interior, using their instructions and products, with fantastic results. I think I also did 3 wet coats. It's been awhile so I'm a bit foggy, but if you look at my Truck build in the projects section, I have pictured exactly what I used. Check that out and if you still have questions, shoot me a PM and I'll look more in depth for exactly what I did. Thanks John! Link to comment Share on other sites More sharing options...
Gary Lewis Posted May 25, 2022 Share Posted May 25, 2022 Thanks John! Scott - I know that you know this since I sent you the permalink to my post on Big Blue's Transformation thread about this. And it differs from what you were told - also by someone at SEM. So I don't know which is the most accurate. Link to comment Share on other sites More sharing options...

Yes, one can definitely get their head spinning with the various ways that are floating around. 77723 (acetone safe plastic) was used here: https://forum.garysgaragemahal.com/Interior-plastics-paint-prep-tp3402p3414.html but you used 3836 (acetone melts) based on SEM tech support SEM Doc I may grab a junk piece of trim and do the acetone test this evening Link to comment Share on other sites More sharing options...

I know I called the people at Vinylpro and spoke with them at least twice too.

BigBrother-84 Posted May 30, 2022 Share Posted May 30, 2022 Hi Matt, Little late to participate, sorry! On my side, I used the ColorBond LVP Refinisher «Light Prairie Tan 150». https://www.colorbondpaint.com/products/l-v-hp-refinisher-ford?variant=311564633 Very similar to the original colour, although not exactly identical. Anyway, I had to refresh all my mouldings, panels, armrests and dash, so I painted everything, no "colour match issue". I find this paint ok, nice smooth finish, fast drying, easy to apply. Maybe a little "fragile" about scratches, but it's probably me who acts too roughly. Link to comment Share on other sites More sharing options...
