so i thought i'd share some of my tips/techniques with all you guys n everyone online that is interested!
this is a bmw e46 coupe interior trim out of a 2001 bmw m3 hardtop.
this is the tools you need:
heat gun, rubbing alcohol, squeegie, a 1/4 part of a squeegie(for smaller corners), exacto blade/hobby knife, some sort of pin popper/needle, large scissors, small sharp point scissors, small paint brush(for 3m primer #94), a shammy, and 3m primer #94(mainly for 3m di-noc, you can use it around edges/groves/ares that have dips in them. just remember once you lay the vinyl down on a area that has the 3m primer #94 on it is best if you do not lift it back up/reposition it.)
wrapping the front of your part is pretty straight forward, once you have found your corners, flip it over and start to make relief cuts around the corners of the backside. make sure your cuts don't go toooo close to the edges since sometimes you might cut tooo close and yes, you will see little spots where the material is short on the front side. once your done, it should look something like this.
flip it over and your piece should look something like this.
now use some primer #94 around the edges of the back, don't drench it, it does not need to be.
now heat up the primer #94 so it dries out, you will see it looks a bit tacky, the key here is to make sure it is dry, not still runny. use your brush to brush off any excess primer #94 that might be to heavy.
now heat up your little triangular flaps to make them nice and flat/smooth. the key here is to make sure the vinyl is somewhat warm/soft PRIOR to you just folding them down! i usually go in sections, don't try to heat up the whole thing and just fold all the pieces back at once, the vinyl doesn't stay warm/soft that long and you might not get a nice and smooth fold over the backside if you do this. this is the MAIN step that makes your work a 10 vs. sup par.
some other examples on a more curvy part
and the final results
sup sup, did this one this morning waiting for my 10am audi job. took like 30min. bmw 1-series steering wheel trim. pretty common for the rubberized finish to peel/chip off on the newer bmw's. dunno why they decided to use this type of material... as you can see once wrapped you can't even tell it was messed up. came out great! this is a out of town job, will be mailing this back & receiving the rest of the interior trim shortly. Wu! Wraps
1 wipe down with rubbing alcohol
2 cut your material
